Replaced engine wiring, kill switch, plugs, points, set points & timing w/ dial indicator 180, timing @ .300 full throttle & max @ .360 btdc. carb jet .071, adjusted throttle cam/linkages, using 100 octane fuel w/ quick silver syn oil, engine starting & running perfect now.

    I guessing the long shaft is the problem. I run a 25 HD Merc with a 15" lower that sits on the transom. If I remember correctly the hub should be even with the sponsons. Go to little boats under 20 there are a lot of guys there posting there cubs .Mine is hanging from the rafters in my garage been 25 years since it seen water lol.
