I have a 1999 23'' Ultra mid cuddy with a 509 Magnum EFI with high flowing exhaust and a 1.65 Bravo one. I tried this Five blade Mercury Maximus 28 pitch prop with a reduced diffuser. The boat ran great very responsive great top end 74mph @ 4900 Rpm. Prop is a little more trim sensitive then my 28 pitch Bravo 1 prop. Anyway as long as I don't romp on it out of the hole. Will this prop hurt my Drive? sphss

it seems to chatter the lower gears more than the 4 blade its bigger and grabs more water so it has to be a little harder on the whole drive as well
