Prop Selection

[willie d]

Hey everyone, I have a 25' Donzi Ragazza with a 5.7L Cobra OMC with a Cobra outdrive. Right now the prop is a 15-1/2 x 15. I was wondering if I should go back with same prop or is there a better one to run on this make and model?

whats wrong with the one you have?

The hub finally gave out. Before it went the boat only ran about 37 mph and some where in the ballpark of 5200 rpms. Not familar with these boats and engine, but I didn't want to run at that high rpm. Also if a higher pitch would give me better gas milage or more performance?

That is pretty high rpm for that engine.
