Guys,
My family has finally invested into the real boat world. I've been around powerboats all my life (I grew up on a 21' Nordic with a blown 454 V-Drive that would excede 80 MPH and pull FIVE sloloms from a wet start), but this is my first boat of my own:
Details:
Rinker 236 Sport Cuddy (approx 3800 lbs.), Mercruiser 454, Bravo One Sterndrive, engine warmed over by a very reputable local engine tuner, putting out 436 HP and almost 500 ft/lb of torque (according to the dyno readout). 22" pitch Bravo One 4 blade prop. Runs about 60 MPH.
60 isn't bad, but it seems a bit short compared to what I see similar boats running with similar or less HP, so I'm thinking the prop might not be right.
I've looked all over the internet and can't find a prop selector that will let me detail the HP. They all limit your answers to OEM engine options.
Does anybody have any experience with prop selection, or have access to an application tool that will help me out?
Thanks. Brad.
