Just bought a new boat for the wife. 16 ft Key Largo w/ 50 2 stroke yammy. Completeing the break in phase. It calls for WOT for a few minutes at a time. The RPM's max out at 2500. The manual says WOT should be between 4500 - 5000. The boat flies. It has an aluminum prop so I don't know if a stainless would make a difference. Any suggesstions
