Hi there , had my 21p mirage look over at the prop shop and check out fine he also put a more cupid in the blades too .. my rpms have dropped from 4500wot to 4100wot and picked up 3 mph . when i trim my 90 24 formula [ heavy] , it seems to have less upward trim before it begins to start to cavitate is this due to what was done ?? any advice thanks

I'm sure it is. Have you talked to the prop shop that did the work?
