    18' starcraft supersport hp rating ?'s

    I was wondering, what year starcraft raised the hp rating to 150hp on the 18' supersport and what year did they change from one bow rail to two. Also thanks for all of you guys posting the details of your rebuilds. I'm sure they will come in handy when I redo the floors on my 16' sylvan sportster.

    Tired of bouncing off waves! Aluminum boats?

    I have a 1982 sylvan sportster 16' aluminum deep-v and I'm happy with it when the water is calm but it will beat your back to death if there is anything over a slight chop. My question is are there any aluminum boats in the 16'-20' range that ride well in choppy water? I would prefer a deep-v...
