    First off,
    can anyone tell me how much HP and top speed a boat with a 305 v8 might have? (boat is 19')

    I've heard that 4cyl's have around 145hp and can pull a ski/wakeboarder just fine, but I've also heard that with 4 adults onboard the boat will basically just drag the person because there isnt enough torque. So I'm thinking 19'+ must have a 6cyl or greater...

    Opinions? :dunno:

    Our boat has a 350 in it and puts out around 315HP I believe. Top speed is about 65-68 MPH.

    I've skied behind a 4 cyl 175 outboard before and got up just fine with the boat loaded down with 6 people. It was a 18 footer.

    Torque will pull them up, HP will keep them going.

    Thanks aCab!
    A bud of mine has a new boat with a 350 and that thing hauls ass. He's the one thats telling me DONT buy a 4cyl.

    I just got back from looking at a 305 chevy v8 with a cobra outboard. He could only run the engine with a hose today because we didnt have time to go to the lake. (his first start failed). If my buddy looks at it and gives me a thumbs-up I'll take it to a mechanic before signing the check. The boat is an '88 Bayliner and has its share of exterior flaws (worst being the hull has a few chips in it). He wants $5k, so its a good starter for me I think.
