Hi, I need an opinion on what outdrive i should run. My boat is a 1986 searay seville 17' bowrider. I am doing a complete repower on it I am also installing a new floor and interior and need a little guidance on outdrive i should use. I currently have a 302 ford and a aq200 outdrive that is running. This unit does not have any power trim on it and am wondering if i shouldn't look for pre alpha or alpha as it does have power trim. Of the 3 of them which one would be the better choice, Strength and Feature wise. I realize i am talking about some old technology here but i don't have the cash to buy new so i will need something in my price range.
