    1998 Mariner 200HP 2 Stroke Starting and Idling Issues

    Thanks y’all! So far, I rebuilt the fuel pump. Old one was leaking slightly, and in the process of looking at things I found a slightly loose clamp on the outlet hose from the fuel/water seperator as well. Fixed both. Started fine cold (albeit a bit sluggish), ran great at high speed, seemed to...

    1978 Johnson Javelin 85hp Sea Horse leaking fuel

    After not running for 8 months I ran some sea foam mixed in with the fuel and after the smoke cleared it runs great! However, after the first day of running fine with no leaks, I saw a rainbow pool in the water all around the boat. The primer bulb was stiff, and the motor was leaking fuel. On...

    1978 Johnson 85HP Javelin idles too high unless manually adjust throttle arm

    Hello all. When I start my motor it is already at a very high idle. I can manually push the throttle arm back at engine and it idles back down properly. When I put in gear and then back to neutral, idle speed does not decrease accordingly. Instead, the idle speed barely backs down and when I...

    tiny cracks in gel coat.

    This is a 1978 Chrysler BassRunner 85. I added the tape measure for size comparison in these pics. I am trying to decide the best way to repair these. Should I sand lightly and use tex? ...or should I just use 5200 to seal? I am not going for cosmetic value here, but I also am not a fan of...
