    pre-power steering

    I have a 1894 mercruiser 3.0L. This is my first I/O boat. I took it out on the lake last weekend for the first time since I bought it and finished the rebuild. As I was driving it in a marina at idle speed it was fine. But then once I put the throttle down a bit I noticed the steering was VERY...

    I think my Shifter is bad?

    I have a 1984 Larson with a 3.0L mercruiser engine. I have been battling a problem for almost 1 year now where my boat will shift into forward, but not reverse. If I tune the cable, I can get it to go into reverse but not forward. The other posts that I put on here over a year ago everyone was...

    mercarb idle keeps changing.

    I took it down to the water today and while it was on the trailer I started the engine checked the dwell. Once the engine was running, the dwell was 24, so I made the adjustments and set the dwell at 31. I reset the timing to 6* BTDC. The engine actually ran much much much better while it was on...
