I'm new to boating and learning about trimming my outboard also. Have a

pull skiers out of the water. Has a 17 pitch prop. Was told that a stainless
steel prop will have a better hot shot, with same pitch. Is that true?

Probably. The stainless will "flex" less than an aluminum prop.
A better idea is to find out what pitch prop is the "right" one for
your engine and load. You'll need to know your WOT rpm's under normal
load.

I used to use a 21" pitch for general boating, and switch to a 19" for
water skiing. Both props gave proper rpm under the given load, and
the 19" gave good acceleration for skiing.

Good luck,

A friend had a new 19 pitch and with that one on, checked the tach and
speed. Boat topped out at 37 mph with a rpm of 4300. Then the tach quit
before checking with the 17. The rpm I'm told should be around 5000 to 5200.

Thanks,
