What is your WOT RPM? WOT RPM with a typical load, correct trim, and an engine in a proper state of tune, is the correct starting point of propeller selection. Post that and I can recommend a prop that will make you happier.

If you have a 3 blade aluminum prop, you will probably enjoy the upgrade of a 4 blade. V8s and 3 blade aluminum props are a bad mix in my opinion. Too much blade area and torque makes for a "mushy" feeling prop with excessive slip. Stainless steel props are a nice upgrade as well.

I just had the same scenario last week . had disscussion with my dealer. It seems when lake testing a new boat, that If it meets minium factory specs., WOT RPM thats good eneough for the dealer. changing the props on my 4 winns 258 cruiser to F-3s Improves that dramaticly. gets on plane much faster. overall performance Is much better.Down side is the props cost me $1200.00 Installed.
