[@jacquespoirier9071]

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

[@michaellicitra7632]

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.

[@rodcros]

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.

[@edwardsullivan5481]

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.

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.

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.

[@bobbygetsbanned6049]

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.

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.

[@jsteins]

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.

[@michaelmartinez1345]

@ 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...

[@IronHeadCycle]

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.

[@philbudne2095]

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

[@machew2009]

On a 2 stroke should really be doing a leak down test and not so much a compression test

[@michaelmartinez1345]

@@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...

Back in the 50's, my uncle from Houston would come down to the central Texas coast and go fishing in the bays with my Dad. My uncle had a 2 cylinder Johnson like this (?) and my Dad had the boat. One time, they launched the boat and could not get the Johnson started. Pulled and pulled on the rope. Thinking some jokesters had swapped the plug wires, they tried swapping them and the motor started right up. A-ha, so they thought. They set out for a reef to set trotlines for redfish. Made it there, set the lines and tried to head back to their camp. Motor would not start. After much cranking and cussing, they swapped the plug wires back to where they were originally and the motor started. Motor ran fine in the morning when they went to check the lines and on the return to camp. When they got to my Dad's home, Dad chewed my older brothers out for 'playing a trick' by switching the plug wires. Innocent of that, my brothers denied doing it. Eventually, the fact that the motor started once they swapped the wires and then had to be swapped again to get it started brought some logic back into the "discussion". Turns out, the shear pin on the flywhell had sheared and threw the timing off exactly 180 degrees TWICE and then remained in the correct spot to allow it to run for the rest of their fishing trip. Long story but quite a tale to hear my Dad tell it. R.I.P. Dad.

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!..

[@sldkjh]

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.

[@josephsfields]

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.

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...

[@CSkwirl]

@@f.h.9606 Yes, you have to make sure you're using the correct lubricant when extensively testing your Johnson

[@jackiehopson8334]

Impressed by the viewers diagnosis. They must have spent many hours in front of one of those outboards

Condenser is the old name for a capacitor. The motor industry seems like the only one that never changed.

[@terrydease5234]

I am not a mechanic but I really enjoyed both episodes. Great job.

[@waynebaird3539]

Although this video is almost a year ago, I must commend you on your skills and determination. Thanks.

[@woodsmn8047]

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

[@neutrino68]

Thanks for letting us watch while you work on your old Johnson.🙂

[@1DIYGuy]

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.

Its always gratifying to get a snap ring in place.

[@collinschubert6940]

LOL loved the echoing flashback complementing the spark plug wires. In my mind this tends to happen often.

My Father worked at the OMC Evinrude assembly plant for 34 years. OMC produced both Evinrude and Johnson Outboard motors there. He did many repairs for relatives, friends and neighbors at home. He taught my brothers and I how to do all of these basic repairs on motors from 1.1hp up to 55hp. My older brother and I also worked at the Milw, WI Plant 2(Assembly Plant) in the mid 70's- early 80's until they shut down. Fill from the top hole until oil comes out. A few drops more or less doesn't matter. My Father always used Brown, non-hardening Permatex on all of those gaskets and the Gear Housing cover. A good tip, always carry a couple extra shear pins, an extra cotter pin and a pair of pliers when you go out boating.

[@ruma7819]

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.

[@agurdel]

The leak is visible at around 49:00, spitting water.

[@reginalddentry7338]

Are you saying he could of corrected the problem and missed a step or is it a Pandora’s box

[@michaelwelsh798]

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!

[@rusty383]

Your dad would be so proud of you to fix his motor .Your Dad put the where and tear on it . I would leave it to Honor him and remember. Some things are just special. You know ❤

[@jaredpeterson380]

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!

[@camm668]

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.

[@greggdsciotto8952]

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!

[@jimwhall6609]

I have a couple uncles like that. Old auto industry guys who could hear an engine and tell you what was wrong with it. To me it was like magic.

[@robertdover2236]

Several years ago I bought a boat that had two engines similar to the one you were working on. I found a guy that could rebuild it but he said I would be wasting his time and my money. When those engines were built gas had lead in it and it would coat the valves as kind of a lubricant (or something like that). He said since they have taken the lead out the valves will burn up and they would need to be replaced. If I had him rebuild them I could only use 93 or higher octane without alcohol. He said any gas with alcohol would burn them out faster. He said he could rebuild it for $600 (that was back in 2004), but I wouldn't be happy for long. He suggested I take the money and put it toward a newer motor. Good luck.

[@testbenchdude]

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.

[@Rickbearcat]

I second this motion.

[@playnhrd]

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.

[@JoeMalovich]

I would approve of more Johnson content.

[@thomasgibson8025]

Here's an aggressive comment. Great job, your right about filling the gear case and I laughed out loud when you got plug bit. ❤ It happened to me way too many times. Duh, you would think I learned. No, double duh!! Thanks for the most excellent video.😊
