Gulfstream Prop Selection

[bls-fla]

I recently picked up a really nice 1990 232 Gulfstream and found a pair of 2001 Yamaha 150 HPDIs for it. The Yammies were on a 28' World Cat so I doubt they are a good match for my Grady. Anyone out there have this boat/power combination so I can narrow down the search for the right prop? ANy help will be appreciated.

15 x 17 seems to be the magic # for many combinations. Why not try what you have on them and see what she does?

I will try what is on it, they are now 15 1/4 dia/15 pitch. After speaking with the tech guy at the prop manufacturer I learned I'm not as far out of range as I thought. He said it was actually a good prop to start with for my setup. Thanks for the reply.

My OLD fict 225 had 15x15 and ran fine
