Hello! I'm looking for some guidance on a new prop for my old mans boat. It's a 19' Maxum (approx 2400#) with a fresh rebuilt 4 bbl 4.3 Merc and a 1.84 ratio Alpha One. It currently has a 4 blade 17 pitch Trophy Plus Stainless prop. The boat runs good but over revs, going 39 MPH at 5300 RPM. This works out to about 16% slip. I'm thinking that going to a 19P 4 blade should get it back into it's power band, but any advice would be appreciated.
