I bent 2 blades on my this my 3rd aluminum prop and will be changing to a stainless so I can tear something else up Any way I have a 2000, Merc 90 hp and am running a 21 pitch aluminum Mercury prop. The motor is on a 2000 BasStream Hydra Bass 1700. The boat is light and jumps up on plane really fast. It tops out at 43 mph at 5200 rpms regardless of the load that's in the boat. Full fuel tank, full live well, one or two people, it seems to run the same no matter what. I don't have a jack plate. The motor is actually supposed to turn 5500 rpms too.
My question is this....Do I go with a 21P stainless prop or do I need to change to a different pitch when going from aluminum to SS?
I would (and have) asked this question in the prop form but all the cool kids hang out here.
