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.

OK will do thanks much

If it's always been slow to plane, it should be easy to fix. If it's a recent problem, it's probably not the propeller.
