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.
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
@pryan05p71 Awesome! This is one of the best idling engines I’ve ever experienced. If they only had just a little more power, they’d be the ultimate fishing engine.
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. ❤
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.
Looks backwards from portable motors. Designed to lay on the ground facing forward when loading? Unusual. Also, seems odd high speed and low speed carb control is so far apart. Must be one is linkage, the other is needle valve? Nice survivor. I have a 55 evenrude to restore.
@Dude1100110012 I agree whole heartedly. It depends on brand for when a FULLY integrated throttle was introduced. For example: The Elgin 16hp made by West Bend 1951, Johnson QD-14 10hp in 1953, Mercury KH7 Cruiser 10*hp 1952, Scott Atwater 7.5hp and 10hp Gold Pennant models 1953, etc…

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

Okay, thanks
I recently cobbled together a tn-26 out of three motors. I’m in love with it.

@GearHeadJP The problem with collecting old outboards is that I think they are all great!
@pryan05p71 😂 If you look harder you’ll find some duds. Unfortunately, you will have amassed a ton of good ones in the mean time.

Great info, thanks
I think it's supposed to leak out of that fitting. I got one running for a friend. It was a pain.

@@GearHeadJP ok thanks
Are you looking to see the Johnson Seahorse?
😂
Sure runs nice
👍
What an awesome time capsule. Just wondering why she seemed to be losing speed on full power, are they just not made to do it on long runs?
@jetstream454 It lost speed because I moved my weight around in the boat. It barely planed the boat if I moved way forward and the rpm’s were higher.
Back when built to last ment something

It’s definitely different if you’re use to their next generation engines. But what a sweet little fishing engine!
Cool
Right!
When did twist throttles become standard? This seems like a recipe for disaster

If you like it you better put a safety chain on it!😢
👍
ruclips.net/user/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
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. 😉
