    1981 Starcraft transom question.

    I have a 1981 Starcraft SS16 I pulled out of a barn last year. For the most part everything is original on it and has seen minimal use before I purchased it. The floor and more importantly the transom is original and in solid condition. I want to make sure they stay that way and I was...

    Noon Rectifier question

    I ordered a new CDI rectifier/Regulator for my Johnson 70hp. It has a short ground wire on it. I realize I am overthinking this but would it be better to ground it where the power pack ground is or just ground it to its own mounting bolt?

    Working on 1981 Johnson 70hp water pump. After breaking everything down, I have a few discrepancies. One, the old Impeller has a metal key. New impeller takes plastic. New impeller is larger(thicker) than the old impeller and the housing is taller to accommodate the thicker impeller. Everything...

    1981 Johnson 70hp idle?

    I just got a cheap barn find. It has a 1981 Johnson 70hp on board. It has an electric choke and a high idle start bar. The motor starts up with the start bar engaged and will continue to run as long as the start bar is engaged. The problem is the bar will not go down all the way without...
