After two years of wrenching on this pig I'm finally getting a little bit of run time on it. The boat supposedly weights 5k dry, and I lightened it up quite a bit by using aluminum heads manifolds and exhaust. Engines are SBC strokers making a little over 400hp in front of BorgWarner/TRS drivetrain. Over the past few years, Ive scrounged every corner of the net trying to find a starting point for props and decided to start with 25 mirage+. Running the boat last night trimmed to the moon and stretching the throttle cables I managed to see 4200 RPMs. Am I way off base here, or should this setup have no problem hitting 5k rpms?
