    Johnson 30HP Needle Bearing

    I'm cleaning the carb on my 1987 Johnson 30HP and have found that there is such a thing as a "needle bearing" located inside the shaft where the tip of the needle valve is. Some parts diagrams do not show this little plastic part but the carb kit I got has it inside and shows it on a diagram...

    GUNK tm Carb Dunk Shelf Life

    Having several boats and a very limited budget, I decided years ago that I was going to have to learn the ways of the outboard motor and fix things myself rather than pay for someone to do it. Looking back, I think the moment I seriously began repairing my own outboards was when I bought my...

    1987 Johnson 30HP Carb rebuild J30ELCUB

    Hello all, I've just completed "cleaning" my carb and was glad to see how well the motor ran afterwards. One problem though. The slow speed needle valve is so loose it turns itself in from the motor vibrating. On the carb diagram there is a part #17 (retainer, friction) that it would appear...

    Troubleshooting 1985 Johnson 15 HP

    Bought a motor. I did my best to check it out good. No obvious visual problems. Checked compression, after a 5 minute warm up 90# on both cylinders after 2 pulls, 100+ after 4 pulls. Started up on 2nd pull. Ran smooth, reved nice, in and out of gear smoothly, reved nice in gear. Peehole pumping...

    Checking RPM's

    I'll put the question first. Is there an easy way to check the RPM's of a 5hp Honda 4 stroke? Did I mention easy? I'm not a mechanic. I have a 5hp honda 4 stroke, 2002 model. The motor runs fine, is great on gas but short on power. When I open it up, full throttle, it sounds like it's only...

    Hello, Not sure if I have this in the right forum, hope I do. I want to build a simple ways to slide a light, 12' aluminum boat into the water from the bank of my canal. I don't want to reinvent the wheel but could not find anything searching this forum or the web in general. What I...
