I spent hours as a kid with my friend Craig as his dad dragged us around the lake hanging on to a truck innertube tied to about 30 feet of rope behind one of those on a 12 foot Sears aluminum boat.
Went stronger than I expected. Idles so low too. Almost on the plane. Pee hole not standard. They spray straight down. Saw one on another video. Lovely little outboard. ❤
It supposed to piss out the exhaust but they route it to make sure the waterpump is working, we had two of them back in the 70s and that was the first thing dad did. Love them ole motors thanks
The factory tell-tale is a port on the fitting just behind and slightly below the idle mixture adjustment. When you spin the motor around for reverse, it dribbles on the top of the transom bracket and rolls off the back. Very little or nothing would drip in the boat. There’s also ports drilled in the shaft housing just above the trim adjustment wingnut and bolt, which is exhaust relief and water discharge. When the motor is running at mid to high speed there should be a good spray of water coming out those relief ports. Beautifully running engine. Mine is a TN-26 from 1950. I haven’t run it for 30 years, need to get it up and going again.
Nice Motor 0 seconds ago hey nice motor. I have question for you. I guy wants me to work his 1955 25 hp Johnson. His say it way low on power. I have never work on a 25hp. I was wondering what compression should be. I checked and its about 88 on both wondering if that the problem before I even start. It runs and has spark in both clys. Reply
Compression gauges vary unfortunately, but your 88psi on BOTH cylinders is sufficient for a good running engine. Did you do it after running to confirm that the head gasket is good? The 25 is really no different than any other twin two stroke. Make sure vitals are good and then work towards pin pointing the problem.

Sounds like something that I’d like to do!
SWEET! That baby is a good candidate for a "how slow will she go" club event! Thanks for sharing.
It surprised me!
Purdy and strong! You can't say that about many HD TD TN's!
It seems that way. 😂

Okay, thanks
This one is my favorite. It purrs like a cat from an almost standstill idle to its highest top end.🚤
I agree, it sure is smooth and quiet. If it only had a little more power it would be the cat’s meow. 😉

Great info, thanks
Had so much fun with one of these on a 14' StarCraft when I was a kid. Run all day on a couple bucks worth of gas.
Nice! It’s such a smooth running engine.
I think it's supposed to leak out of that fitting. I got one running for a friend. It was a pain.
👍
Sure runs nice

Back when built to last ment something

@@GearHeadJP ok thanks
Cool
Right!
Are you looking to see the Johnson Seahorse?
😂
czcams.com/users/shortsNsm_-RXxB-g This is the one I got running for a friend. I think the fitting got moved on the one you have.
Okay, thanks
If you like it you better put a safety chain on it!😢
