    Prop Size Recommendation? Bayliner 2450-gctid396937

    I have a 2450 Bayliner Command Bridge, and it either has a 14 x 21 L prop on it.

    THe boat has trouble getting on plane without moving weight to the front, and using trim tabs. Someone told me it is overpropped, and I need a 19 or 17P L prop.

    Any suggestions?

    I'm curious what other people are using.

    Stock was 15x17 on the low end, 15x19 on the high end. I'd go find a 15x17 and try it. I'd also make sure it was a genuine VP "big ear" or speed line prop. I was able to swing a 15x21 on my 2450 bowrider, but I also was running 800 lbs less weight since I didn't have the superstructure you do.

    You need to see 4200 - 4400 rpm wide open.

      Talk about LUCK. I found this prop on craigslist, and picked up the L rotation prop for 25.00.

        See my recent response to your other thread.

        Since you mentioned 21" pitch and/or 24" pitch, I'm thinking that you need to check your drive ratio before you start trying props.

        There is no substitute for the correct final drive ratio.

          Actually that's really good advice. Check your gear ratio too...no idea if someone has monkied with it or not.
