Default Newbie need prop size help!

Hello, just bought my first performance boat a 1990 Sunsation Rocket. I believe it has to big of prop on it. It has a rebuilt 454 with some head work and intake manifold so the horse power should be about 350-375 (and bravo 1 drive). It currently has a 26 pitch 4 blade mirage prop and I only get 4000rpm at WOT and 60mph (gps). Please help I'm a newbie! Thanks!

Not familiar with the boat, but I would guess a 3 blade Mirage plus would work better and probably a 23 pitch. What size is the boat and approximate weight?

I think that is a 24ft boat, and I agree with Sledge that a 23 mirage plus would be a good place to start. I've never had much luck with a 4 blade prop on smaller boats like that unless you want a killer tube puller. You could try a 24 Bravo1 4 blade if you can borrow one. You need to get rpm's up higher to get maximum performance.

Sorry guys left some info out, it is a 24 foot boat and is about 3000 pounds dry (i think). I had me and my buddy in it so add 350 pounds for us and my gas tank is 50 gallons.
