building power for my 10 meter prop help
 

i am building power for my 1985 10 meter
new power will be 575 hp with trs drives and hubber trans

boat ran low 70 with 440 hp stock with 25p 3 blades

any one have good idea on what p prop to run with new power ?

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 ?

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?

x2 that is what I had on mine when I sold it. ran into the 80's with 26 hydro's 580 hp .

575 hp 454

At what rpm???

machine shop is saying 5300

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.
