Re: stamas 310 tarpon c/c t-225 4-strokes or 250 hpdi any opinions?
What can I say...ya can't get much bigger motors. Unless you want to try three.

I have twin 2-stroke Evinrudes Ocean Pros, 175 HP, and it flies with six on board. 24' Boston Whaler Outrage with T-top. A T-top will knock off 2-3MPH, too. About 42-44 MPH in a three foot chop, WOT. It'll cruise at 32 MPH. All figures with six onboard. You're boats
a lot bigger and heavier than mine. What's does Stamas say...not the dealer, if you know what I mean? Stamas is a great boat, I'm sure they will be straight with you. My personal guess is that it would take more time than you would like to get up on plane with that load (don't forget fuel) and the top speed would be around 36-38 MPH. I think you have a ligitimate concern and should take your pals for a ride. Be sure the tanks are full. Often a dealer will not do this; intentionally.

Finally you'll want to have the quick power to run in a head sea, 5-6' plus. You need a test ride!
