The reason I ask is that I'm considering a Powerquest 280 that has a Precision Marine 502 that has been modified to run naturally aspirated with 540hp at the crank. I believe this is equivalent to a HP525's power. The power was made with Dart high flow aluminum head, ported and polished intake manifold, high flow exhaust manifold, and a different cam. ECM tuning as well of course.
Am I basically getting an HP525? If so, WOW!

A 525 makes about 500 at the prop. Most will dyno, as JC mentioned, at least 540ish hp at the crank. Been done many a time. Most loose about 10% hp once they make it to the prop via bravo. I dont think merc lists any motor at the prop b/c it doesnt tell anything. They make too many drives and motors that can be interchanged like a 525 with an XR, #6, and according to merc racing now an NXT. All those drives eat up different power.
