Hello everyone!
I have a 1957 Johnson Seahorse, as mentioned in the title. Carb rebuild last year, resealed lower unit, new impeller and some other random stuff. It has the lower unit shaft extension. It's in good condition for the age, runs well.
I know you can't give exact numbers not being...
Well, I started her up! As far as I can tell she runs SWEET. I didn't get the rpm's all the way up because there's no load, so I'm waiting until we can go to a lake. But I got it as high as it was having problems last time and it did great. It is pumping a lot more water since I fixed the broken...
So I finally got it all back together. I got some car door seal for the cowling off Amazon like @Crosbyman said, and that worked sweet. The last thing is I can't find that huge bolt that sandwiches the extension on the bottom back of the lower unit, so I'm gonna have to find that before I start...
Oh, I leak tested the gearcase AFTER using the rtv and it leaked. It was that propeller shaft seal, where there's metal on metal contact where it presses in. I was mad because there was rtv and already oil in it, but I got it apart and back together and now it doesn't leak a SINGLE air bubble.
Updates yes, fishing no. (But soon!) I haven't been working on it much because I've been waiting on parts, but the last one finally arrived yesterday. I started putting it back together but didn't get very far before I had to stop for the day. But tomorrow or the next day I should have more news...
I made a tool for pressure testing the gearcase. I drilled down the center of a bolt, clamped a piece of hose to it and clamped a pressure fitting to the other end of the hose. I hooked it to the air compressor set at 10 psi, and like I feared the gearcase leaks. It's at the front where the...
I got all the new seals in the gear case and I got it back together. It shifts and operates like it should. I don't have any special tools for leaktesting it, is there any way I can do that DIY? Other than putting it in a bucket of water then taking it out and seeing if there's water inside...
