"I purchased a 1965 33 Hp Evinrude Ski Twin last summer and used it several times before winter set in. The motor runs GREAT! The only problem I have is when running wide open or nearly wide open the outboard "jumps" every so often.
Hard to describe other than that. It doesn't seam like a miss, more like a hard slip. Someone told me it could be the clutch dog, but another person on this site said he'd be surperised if that is what it is.
Please, any help would be appreciated. Need to get ready for fishing season.
Thanks in Advance,
