    i have an '86 johnson 25hp tiller longshaft that is way too long for the transom on my 15ft alumacraft. im wondering if it can be converted to a short-shaft, what all parts i would need to buy, and about what it would cost. im even up to trading parts or motor if anyone is intirested.

    My wife said no when I asked her about converting my johnson to a short shaft

    Do the jack plate. Buy it or build it, but if you can't get one that'll lift your engine at least 5", then build it

    I don;t know what you have access to,or what kind of boat you have.I have used a piece of SCAFFLE BOARD on a John boat.It is about as strong a board as you can get.Some one working construction can get you a 12-20 inch trimming,as they sometimes have to cut them off to fit in a place.You may have to plane off the end where the clamps fit,if they will not open wide enough.I had to do this to swap a 8 & 25 hp.long shaft on the same boat.I sometimes used the boat in a 10 hp.and under restriction area.Do all of your cutting,drilling and fitting.Then soak it in a good water seal.It will last many years.peewee-williams
