Keep us updated with props you try. I've got a f115 on my 20 and will be trying new props as soon as money allows

115 2 stroke yammie on mine. Running a black diamond 13 3/4 x 15 aluminum prop. Cruise 25 mph at 4000, 27 mph at 4400, WOT I can stretch out to 34 mph at 5500.

That's with a moderate load. Thus far weight doesn't seem to affect my planing ability. 3 big men behind the console I can still plane out no problem. I'd like to really load her down and see what happens, just haven't had the need for it.
