A good friend of mine owns an '85 10 Meter as well with approx 550hp on each side. He swings 26p Hydros and the boat seems to like them a lot.

what kind of mph is he doing ?

Griswald

77-80 depending on conditions at around 5400 rpm

The question is how many RPMs do your engines need? Are these 575HP 540's that only need 5200RPM, or 575HP 454's that need 5800RPM?

Bblades has the test program which will let you try a few different props. I'd throw the 26s on there and let it eat.
