Re: 1957 Big Twin 35hp questions oil, engine "Bucking"

[danblue]

I just had the lower unit rebuilt because my skeg was cracked, and I found a good unit from a 1957 Johnson Seahorse 35hp. My mechanic used the new gears as mine were a little worn, and the shift dog, etc. were all fine. He interchanged a few items..he used the best from both motors.

It doesn’t feel like hitting a submerged log, it’s as if the engine switched into reverse at high speed for 1/2 a second, then corrects it self..It actually feels like and sounds like an air pocket makes it’s way into the engine, hiccups, then catches the fuel and back to normal…the gears never slip at all…ever, and I can shift really smoothly (although I jerk it quickly at idle as I’m supposed to) but I notice I can push the lever into gear a lot easier than last season since the lower was rebuilt.
