Long video, but I did a ton of work and it was a real challenge to condense it to under an hour! I hope everybody enjoys it! What do you think of the longer videos like this? I figure people can always watch it in 2 or 3 sittings if they don't like them that long. Have a great weekend everybody, and let me give another huge thank you to Pappyfromthekeys and Jacques Poirier!
I don't mind the long vids. My other 2 channels i keep up with have long vids: Andrew Camarata and Jesse Muller. Yall 3 are the only ones i have the bell notification enabled
As long as it's actually interesting, long vids are fine with me.
Is the ring job gonna lead to more dad jokes? because I could go for more dad jokes :D
Great vid, I prefer the longer vids no doubt. Yeah.
i'm good with long videos. now, take today's engine, let it sit as long as this one did... i don't think it COULD run again. just goes to show how new is never going to be as good as good old. love the work and effort. thank you
Am i the only one who finds it incredible that all these parts can still be sourced?
Right? Pretty wild.
I’m in need of parts for my 1953 JOHNSON TN-28 if you have a parts source.
It’s always a shame when your Johnson starts acting up with old age
lmao
...and then gets diagnosed by strangers online.

The first video I watched was the porch rebuild. Personally, I'll watch Your videos no matter how long they are. Your knowledge and single-handed jobs that You show us are awesome. Its amazing how much You know ,being a jack of all trades. Thanks for making these videos. Always worth watching, the longer the better.
Stumbled upon this video today. I repair a lot of stuff and although I'm not repairing a motor like this I LOVE how you zoom in and show detail. A lot of folks skip over the details but you do a great job showing how these things work and the order parts go on and off. Bravo sir!
Grate bit of entertainment.

before going deep in the engine block, try a gauge with a shorter hose, the cylinder capacity is so small in comparison with the hose volume that it can cause a false reading, a good idea is to do a wet test before shooting anything. usually, when the compressions becomes low due to wear or stuck rings, the readings differs from one cylinder to another, in your motor, they seems to be very even. If the cylinders are not scored, you can try a cleaning treatment as seafoam, sometimes, it can frees the rings so you don't have to open the short block very good video
More good tips from Jacques! Thanks again.
It’s the legend himself.
@@FarmCraft101 marvel mystery oil added to fuel mix with sea foam helps unstuck rings it worked for my 1956 McCullough Scott 25 And 19 57 mercury ... and you can tell by exhaust note when running dead on perfect ... on occasion with my older outboard engines For my fuel mix I use 100 octane racing fuel it really makes a difference even on smaller engines... my 50 Scott sea flash and Chrysler Outboard really wake up on race fuel mix ..... great video thanks for information... and taking time to share
Great job Jacques! It takes real skill to just listen to an engine... THROUGH THE INTERNET.... and diagnose an issue. You guys are the true heros of social media and the real reason why it should be around IMO. Thanks for sharing your wealth of knowledge with everyone else :)
Knowing to think of the length of tube for the compression test...where that is taking up a fairly significant volume of available air-space and giving a false reading...I call that brilliant. *Chef's Kiss* to you.
Very good video! I noticed that the engine after the work did not look like it was pumping as much water as it was before. The telltale was streaming very well before you disasembled the engine. I believe you are losing water internally in the end of the shaft area where the power head mates to the lower unit and here is how: The black carbon ring that was very brittle and broke is a sealing surface and seperates the pumped water from the shaft. It iis by design very hard and brittle and seats itself on the shaft seal. This is somehow part of a chamber where water seems to be accumulated and routed into the engine. Also, the spring is what keeps the carbon seal slightly loaded to effect the action of the seal. The design is not faulty as you think. I really suggest you look at the parts illustration and see how this works (I am guessing here) and your water pump output to the engine block will increase substantially. You did a really thorough job but cooling those engines is really critical.
I died laughing when he went to the old clip that said "I'm amazed these wires look good they don't need to be replaced" great editing 🤣🤣🤣
Wondering when my favorite farmer was gonna chuck a video up !
Longest video I've ever made. Took literal days editing, and just finished! Phew! ;-)
Yes, please - new rings. I wanna see what this Johnson will do when it's firing on all cylinders and full compression again!
Yeah , do the ring job !
As a backyard mechanic I leared a lot and especially liked the way you admitted mistakes or omissions like putting parts backtogether again. if there are no bolts left on the bench then rebuilding is a success. Many times I find one bolt left on the bench so to me that's success to me. Ha Ha Ha....thanks for the video on the Johnson and the tactor back hoe hydraulics. Dan, Mishawaka, IN.
I hear Johnson rings improve performance.
ONLY IF IT TRULY NEEDS RINGS
Compression test first
That flashback about not needing to change the spark plug wire had me 🤣🤣🤣.
Great video. I actually worked on these back in the day. I was an outboard motor mechanic at an Evinrude Dealer - on the water marina from 1959 to 1963 while in high school. My uncle actually owned that exact Johnson and took me fishing with in Lake Chetek WI when I was 12 years old. Never had to work on his though. By the time 1959 rolled around most every one upgraded to 5hp motors with both Fwd and Reverse gear shifts. OMC recyled that clutch design in the early 60's with separate electromagnets to engage Fwd and Reverse. Good memories for me, thanks.
i had one 2
You make good videos
Yes please on continuing the work. Since This Old Tony is on hiatus, we need more creators who can make and fix things.
This old Tony has just put a new video out 😁👌and it was good Tony from Western Australia 🇦🇺
Mustie1 is where I get my fix at, when needed.
Btw. I love long videos.
This is a GREAT video. We viewers had a good camera angle to see things well. You did a hell of a job on this engine figuring things out. Now you need to go fishing.
When it's running on one cylinder you can hear it carrying the other cylinder, it has a distinctive sound that's hard to mistake once you recognize it. I was an auto tech for 30 years, I did run-ability, fuel injection and electrical. You can pick this sound up even if it's a 12 cylinder...
Ngl, hearing you say "lemme get a pointer" brought me back to the bad bitch that came to watch me and my brother who taught me anything from how to revarnish a table to fixing cars and small motors. Thank you for the blast from one of the best parts of my past and may she rest in peace.
"Torque specs? HA!" was pretty much the answer when I asked about that for so much of the mid-century machinery on my father's dairy farm.
My gosh so many of those old boat motors look like mechanical Art ....just beautiful
Coming from an electrical engineer, a condenser isn't "similar to" a capacitor, it is a capacitor. We just don't call them that anymore outside of audio equipment, for some reason.
They both can knock you on your but.
@@brentmcmahon8188 i mean, it's a bulk accumulation of charge in a confined space, what else would it do other than discharge or occaisionally explode?
Good job Jac and Pappy!
Back when things were meant to be serviceable and repaired when necessary.
We could do humanity a big favour by going back to those days.
@@eddiehawkins7049 We need to pair that old mentality with modern technology and materials.
Exactly. It's sad that few people seem interested in fixing old equipment. As I get older it's getting harder and harder to get my Johnson serviced.
My dad bought a 5 hp Johnson for me when I was 10 in 1960. Stayed at a resort on Leech lake MN. For the summer. Hearing that motor running out on the lake was like music to me. Thank you!
nothing better than when the old johnson is working properly... (
When my outboard ran on one cylinder, it was wobbling a lot. Last video I thougth this is just how old engines sound, but it sounds much better now!
So that's how you tune up your Johnson, I'm going to try that on mine---
The oil from bottom is a hold over from many marine engines from WW II! Then, the gear boxes were filled with grease, like a grease gun. It was always added from the bottom to push all the air out of gears. Your Chinese finger thingy is a device to keep engine from running backwards as 2 stroke engines are capable of, especially at low speeds
Really like your approach to problems and the patience you have. Thank you for taking the time to edit and post quality content.. This is the same engine my grandfather had and I still have it. I'm now inspired to see if we can destroy it or either get it running! Hopefully running.. Not destroyed. Thanks again, enjoyed the series of vids on this engine. 👍
Some people would see the top port on the gear box marked FILL and the bottom marked DRAIN. And still argue that the manufacturer was wrong.
Glad to see you cleaned up all those fluids after your Johnson exploded.... This series has been great btw :D
It is a lot of fun to repair older stuff. You can see what is going on with each part and replace it if necessary. Modern stuff is huge wiring harneses with black boxes that cost hundreds and no way to tell if they are the problem!. I love it when it cranks after we get the covers back in place.. My dad had a 12 HP Johnson that we used for years. Thanks for the great video!
My mechanic made me promise that I would never again try to change a water pump impeller. He spent a long time getting that shaft back up in. Fine video.
Enthralled, immersed and impressed for an evening's viewing - DoB 1950 - UK
My favorite thing about these old engines and other machines are the mechanical solutions to electrical problems. Life before logic gates and microchips took a lot of creativity
I never get these comments. As if throwing microchips on something magically resolves problems. You just introduce a boatload of new problems that need their own kind of inginuity and creativity. Always the same "mechanics good, informatics bad" ape-like mindset. Take a look at ben eater to really get used to what kind of problems you get with informatics and how inhumanly complicated it really is to solve something with informatics. You need both mechanics and informatics to build the real crazy machines. I mean hadron-collider-class of crazy. Where nearly everthing is machined and programed to absolute perfection.
No kidding. Used to be that,usually, if you had a spare plug and shear pin you could probably get your outboard home..
I am amazed at the 1950s engineering that went into designing the components to fit into a compact outboard motor.
Jack of all trades is a master of none But then oftentimes better than a master of one
When I was a kid, I with my granddad fished with one of these. Hearing it in the video, it did not sound like I remembered. I just figured time had overcome my fond memories. BUT maybe I was right to feel something was not right. THANKS fellows for helping me feel good that my childhood memories are some of the time true .
I am not a mechanic but I really enjoyed both episodes. Great job.
Only catching up with this video now (2 years later). Thanks for taking the time to make a very satisfying and informative video.
Although this video is almost a year ago, I must commend you on your skills and determination. Thanks.
Pro Tip: The reason you put the gear oil in the bottom is because water and greasy water floats, so if your just doing maintenance it pushes out any lighter than 90 weight contaminants. You don't need any special equipment just the lube in a tube.
Wtf no, water does NOT FLOAT in oil! These types of cases are known to get bubbles trapped if you don't fill from the bottom, the bubbles will float to the top instead of getting trapped if you fill from the bottom. Any good marine gear oil will have dispersants that keeps the water suspended in the oil anyways, so you can't get rid of the water without fully draining the oil. If your oil looks milky it has water in it which means you have a leak.
Nice brass remake for the broken seal rung under engine mount. At 27:29 when putting the lower end together, your 3-bolt backing plate is off center, and clockwise about 8-degrees; but should not matter, since the force when tightening bolts still distributes evenly on snap ring. It is also visible on your "pleasing snap install" repeated at the end. As for changing the rings... 2-stroke engines are pulling fuel/oil/air mix in from carb through lower case *under* pistons (giving lubrication) then mix goes through side intake port. This means blow-by past rings mixes some exhaust with intake, reducing power. BTW: see if your compression test goes back toward 80psi with throttle wide open, and after you spin engine 5 seconds with plug wires off, to add some oil mix to cylinder walls. Another trick to check for cylinder wear, and blow-by past rings: (1) Attach socket+breaker bar to nut on top of crank and *hold*. (2) Turn regulator down below 50psi on compressor, and attach line directly to pressure test hose going into spark plug hole. (fittings are the same). This will try to toss wrench, so hold first. (3) Slowly turn wrench+crank 2/3 of stroke until starting to reach exhaust port. Listen for changes to sound of blow-by air hiss and you should be able to tell if ring seal is even for different parts of cylinder or worn near TDC. (4) Repeat for 2nd piston, using different TDC position. Some air going past rings is normal; but you don't want excessive smoke going back in lower case while running. Also check for worn seals where crank shaft comes out of case. Leak around crank seals on 2-stroke can suck air, causing you to run lean/hot at high RPM.
@ Joseph Steinhauser, good observation of the replacements that are required of the Upper and Lower crankshaft seals... This alone could really bring that little 2-stroke twin back to life... I like using the 'cranking type' of dynamic compression testers on engines, which will tell if excessive leakage is taking place, Anywhere between the cylinders, Pistons & Rings...
Wow! The sound of the engine running take me back to the late 60's and early 70's with my dad. I would be so tired from getting up early and fishing all day that I would fall asleep in the bow propped up on a couple life jackets. I look at his 1943 Johnson Sea Horse 5hp almost everyday in my basement. I wish I had half your talent to rebuild his.
I'm 69. Lived on the Rogue river in Grants Pass Oregon as a young man, 11-16. My dad had an old wooden boat with with aluminum skin and that same Johnson engine. Our river bank was difficult to navigate without hitting rocks and shearing that propeller pin. I cut some nails up to make a bunch of shear pins so I would be able to head out and be able to change the pin every time I hit a rock. I got used to the rock locations and rarely hit them. My dad not so much. He'd head out with a buddy of his and hit a rock every time. I had to coach him. Every exterior part of that engine and the cotter pin/nut/prop/pin assembly brings back great memories. Took it apart 50 times at least. I could go up river through a couple small rapids till one matched the engine power and the boat would stop advancing. I recently thought about going back there and boating up through that minor rapids. One of those things.
Regrind your lathe parting blade. Grind the end so that the right side cuts off your newly turned part 1st. This allows parting bade to advance a couple of thousands and remove what is left. Great patience ... or good editing. Thanks for the mechanic lesson.
Come on, we all know that you want rings for your Johnson.... Actually, I like the idea of a complete rebuild of that engine - I think it deserves it.
I gotta say, the design of this little motor is quite elegant
This is why i love mechanical shit. Peolle keep telling me about "advancing the spark with the ecu." I'm gonna go show every one of them this video because THIS is what made it click for me.
Make sure the throttle plate is wide open when you check the compression, it makes a difference. If there is no air to compress (closed throttle) the compression will read low.
Throttle position shouldn't matter on a two-stroke and the engine out of water exhaust port is another path for air to get in
On a 2 stroke should really be doing a leak down test and not so much a compression test
@@philbudne2095 the exhaust is not a path for air to enter an engine (2-stroke spark ignition engines included) while it is cranking... Intake air & fuel goes through the induction system then through the reeds/or rotary valves/ or the piston ports & into the crankcase, where it is compressed, then forced through the transfer ports and into the cylinder while the exhaust from the previous cycle is forced out by this incoming air flow, from the transfer ports, then compress's & ignites the incoming charge... The throttle & choke must remain open for an accurate compression test...
@@michaelmartinez1345 In a compression test the gauge is screwed in in place of spark plug and no ignition takes place, so there is no exhaust, and air can enter via the exhaust port. kzhead.info/sun/dMureZegiYOwgnk/bejne.html
thats actually what I wanted to say, but not mechanical enough put my two cents in Thank you ironhead cycle..
Suggestion to add a random part number to future video titles. It will confuse the hell out of new subscribers, some won't get it, but a few of us will know the ridiculousness of no part numbers on hydrolics
That spoony screwdriver is your real secret weapon, I'm going to steal that idea. And thanks for showing us your Johnson.
LOL loved the echoing flashback complementing the spark plug wires. In my mind this tends to happen often.
I vote for the rings. I learn a lot from watching another man work on his Johnson even if it's much smaller than my own. Mine's a 1978 Johnson SeaHorse 120 HP. It's a two hander but still all the same principals. Other than that, I'm not surprised that the country is divided over how to fill a lower unit. Anyone that shares the way they do it is a friend and anyone that tries to tell you how you got to do it is should be dismissed as a Karen.
And seals
the size of your Johnson only matters if it is getting wet regularly

Well , my johnson needs an overhaul too . couldn't resist
Thanks for letting us watch while you work on your old Johnson.🙂
One of the best videos I've seen in a while, very enjoyable. Your video editing and humor are great. And, Johnson jokes are always appreciated!
Hi from the UK. Just for your info condensers and capacitors are one of the same. Capacitor is the modern name for condenser.🙂
I think you are remarkable! I have fixed a lot of things in the last 80 years but you didn’t give up. Antiques really need to be remembered.
Not a single one of us that watches KZhead does not use KZhead for learning purposes. I am one that is always learning. That is why I spend as much as 4 to 5 hours every day of my life watching videos. That may sound excessive but I am retired and still learning. To me I would go nuts without my iMac 27 inch computer with good sound hooked to it. Love to watch music too.
10:40 lmao I'm loving the echoey-voice flashbacks from the previous video 😂
Your 100% correct in filling this model from the top as it has a kind of an open chamber large oil cavity. Later models designs was changed to a smaller closed chamber system requiring filling from the bottom. Most people dont know this and say fill from the bottom understandably. Nice Work with the machining lathes are always handy .That bottom ring that broke is made from carbon possibly so it is very brittle. These TN models were big sellers in the early 50S for Johnson they sold thousands of them and there still around today, great little kickers. The proof is in how nice it ran on one cylinder. Which is how they were designed if a problem with one occurred ,so you got back to the dock instead of rowing and cursing, LOL!..
Nice to know how they were designed. I found out my Evinrude 15 hp was running on one cylinder after I left it at my uncles place. Sometimes it would have 15 hp, sometimes it would have about 6 and guzzle gas... The ignition lead just had to be replaced and it would have been ok again. It probably still is at my uncles place but I can't use it anymore in the city because it is a 2 stroke. I would love to be able to use it again because it was a kicker when it ran on both cylinders and it sounded very nice.
Dude my fucking chest hurts from laughing.... "a 1 cyclinder mower sounds good too" *finds out one cyclinder is dead* im crying and subbed
There was something hilariously comic in looking at the poor guy getting shocked multiple times while checking for spark on the wire that wasn't working before 😂
Its always gratifying to get a snap ring in place.
great video, great machining. But you forgot to put on a parts-number (on the machined bushing)
Hahaha! Darn it, that would've been a great addition to the video!!
@@FarmCraft101 ...If you are going to tear it apart to do the rings, might as well remove that bushing and stamp a few numbers on it.
Fritch's corollary to Murphy's Law is that, "Murphy was a damned optimist!!"
love these old Johnson's remember them fondly from my youth ... no not quite like that ....but from fishing on Henrey's lake two Johnson's engines one for power ..a thirty five horse .. and another like this one for trolling
Thanks for the detailed video. I have a 1950 Johnson TN 26 that is very similar, but it has the older style coils and points. After cleaning the points, I have good spark, so I'm leaving the magneto alone. I put a new impeller in the water pump, and it ran okay when I started it up several years ago. This year, I decided to get it out again, but the carburetor needs to be rebuilt, so I am thankful for your explanation. Keep up the great work!
Just the " 5 Sea horse" decal is worth the work on this old Johnson ! PS: Rubber O rings should be rather lubricated using Glycerin or a water soluble lube not grease .
Awesome video. When I was a kid in the 90's, I had a '67 Johnson 6 horse on a small aluminum boat that I had lots of fun with going around the lake at my grandparents summer cottage. I would agree that a new head gasket and rings would help to bring the compression back up to new and give it its full power.
HEY ,you made a great video.This was good to see that there are people that still enjoy old stuff and have a ability and ingenuity to fix and sometimes improve valuable motors like this.Everything you were doing was stuff I've done myself in the past and it's just so much fun.When it back fired after you started it the first time i said OH SHIT!!! I'm sure so did a bunch of us. BUT you showed that remaining calm and using your noodle you CAN COME UP with a solution. So thanks
Really loving the long form videos. I'm having a bit of a stressful beginning to the weekend so it was super nice to come down to my home office after everyone else had gone to bed and just tune out the rest of the world for almost an hour. Many thanks, man.
I second this motion.
Thank you! This helped me understand how my old lawn boy mowers without solid state works!
I saw what you did there. It's Putt putt putting up a fight. Doh !! 😂
I stayed through the entire video. What a fight! What a series! Can't wait to see the epic conclusion. Awesome to see your various skills at work to create parts on the lathe.
Commenting for the “engagement” I love your videos and the long ones are especially a treat. It’s fun to watch someone go through through the thinking process and solve problems as they arise. Keep up the good work!
My first outboard was a 1966 Johnson 3 horse, brings back some memories!
John, you got a big-nosed happy-faced Johnson behind that snap ring… this was fun to watch!
I love your willingness to learn and temper control. I can tell you, this Christian man would have had some asking for forgiveness after some of those encounters. :P But thankfully a little grace goes a long way. Also That was a genius move to fabricate that part as a whole. Great replacement idea.
Heard a little AvE in your presentation. I truly enjoyed your efforts and your commentary, measured and thoughtful, thanks for the video. I suppose it was a blast from the past that my first outboard experience was as a young teen with a Johnson 20 in the 60s. I agree with you, the length is perhaps an issue, but those that wish to see every step will appreciate it, and those uninterested have the opportunity to fast forward to the finish to see if you were successful. Thanks again.
I have the same Johnson Seahorse I bought years ago, used and had set for years. I was in my early 20's when me and my great uncle started working on it and got it running, not good but running. After watching your videos I believe it's time to bring it back to life again with the help of my son. This will be a great opportunity for him to learn just like I did how great things used to be built back in the day.
I really enjoyed this series on the johnson motor, you're perseverance is remarkable, of course having the right tools really helps, good job!
Regarding the compression, i recently fixed an old chainsaw for a guy, he'd been running it on cheap 2 stroke oil and it had very little compression. I did not remove the cylinder (so nothing was upset) and put in some good mix with full synthetic 2 stroke (Motul 800) and the compression about doubled, completely different saw Also the piston had a LOT of wear, looking through the exhaust port it was polished shiny and the ring was well worn, whole lot was due for replacement but got it running good enough for him
I'm behind this. Your Johnson seems to be pretty strong the way it is. No need to fool around. Like Skwirl said, just use some good oil and give him some time. Otherwise, if you have too much time on your hands ... fooling around with your Johnson is always a good way to spend your time...
@@f.h.9606 Yes, you have to make sure you're using the correct lubricant when extensively testing your Johnson
Great video and series. You have fought and got it running pretty good. I would absolutely put new piston rings in it, do an air leak test on the engine to make sure the seals are still good and fix it up to its full capability. It would be a hard kick to the Johnson to leave it under its full potential. You are so darn close to 100%. Come on man you can do it 💪
It looked as rewarding to do as it was enjoyable to watch! There is nothing like fixing and learning. Congratulations! Dave
Hah when i was a kid,my sister was able to get me water skiing on 2 ski's.Dingy fiberglass,she would move to front then magically all the sudden i was able to pop up out of the water.Took alot of try's but we amazed the other lake folk that laughed and said it could not be done.My old Johnson 5 really had it's work out in those past summer day's.Thank's for vids .Longer vids i say ok !
I love your videos man, I'm just a teenage city boy but seeing you find out creative solutions and use a lot of patience and dedication is really cool and entertaining. ill probably never have to repair any Johnsons (I hope not at least lol) but its very educational watching your channel. keep it up!
Might as well and do the rings, then you will have a complete rebuild.
Do it, you will be so happy with it afterwards! That Seahorse is such a good motor! 👍
I enjoyed this series... I like seeing old stuff being restored and made useful again! Good work!
Great videos! One thing I noticed is you put the impeller in and didn’t see and lubrication on it. On Sailboat diesels we always put some Vaseline in the pump so the impeller has some lube before water pressure would be the lube. Not sure about 50 year old Johnsons, but thought I’d comment. Thx!!
Some lube is a good idea if you want it to last a little longer.
I knew that guy who's Johnson was only firing on one cylinder
gotta give him props for fixing his johnson
Nice work .. takes me back to the really good old days working on all kinds of engines .. car and outboards… you could keep them going with paper clips !!!!!
This series has been fun to watch. It has inspired me to get my old outboard going. Similar story to yours, I inherited an old 1958 Evinrude Fleetwin 7.5. It's in really good shape but it hasn't been started since the late 90s. Im sure I'll need to do some of the same repairs that you did in this series. It'll bring back so many great memories of when I was a kid tooling around West Twin lake in Lewiston MI. Once I get it running I'll put it on my grandpa's old Lone Star Little Fisherman just like a did so many times as a kid.
I think you messed up the adjustments on one of the points. The crank lobe wasn't aligned with it and the backfiring could possibly have something to do with that. It also seems like you have an exhaust leak on the stem. Probably a broken rubber seal there too. Well, old rubber you know. If you're going to take apart the head I would definitely change the crank shaft seals in the same process.
The leak is visible at around 49:00, spitting water.
Are you saying he could of corrected the problem and missed a step or is it a Pandora’s box
You are so patient and handy! Congrats!
I'm not paying for the overhaul so DO It! You will have a new engine and your Gramps will be so proud 👏 😊
Always measure compression with open throttle, might give you a slightly better result. Regarding the new alu/bronze seal, between the leg and power unit. The old stainless washer looked as if it had been "rotating" on the o-ring, by making it one piece you loose this flexibility. I wonder if that was going to cause problem over time, that the alu/bronze now sitting directly at the bushing on the shaft being the sliding point instead of the washer and the o-ring.
