I've got both a 1993, and a 1999 Starcraft SF14, both are short transoms with a 40hp rating. I run an older 35hp Johnson on the one, and a newer 9.9hp Mercury four stroke on the other. Both are open hull tiller type boats.
I just looked into repowering my one boat with a new motor after getting a sort of crazy offer for my 35hp two stroke, but found that if I sell my motor, the chances of finding a new one may be pretty slim. None were in stock anywhere. A tiller steer, shortshaft, Electric start, with tilt/trim seems to be hens teeth right now. A few dealers told me if I like my current motor, and it runs, stick with it because any they get in are are already sold for the foreseeable future.
