Next prop size?

[v1_0]

Hello,

I have a 20' Galaxy with a Mercruiser 4.3L, alpha i/o. My current prop is a Michigan Wheel 031025, 14 x 19. I ran into some 'treetops' (reservoir created by damming a river) and should probably replace the prop. (Bent up the tips of the prop a bit...)

I did a bit of tuning on the motor and WOT seems to run a bit high 5K (recommended is 44-48k) with a normal load (3 kids, wife, cooler, dog, full gas tank).

Should I go to a 15 x 19, 14 x 20 - or just go with a new 14 x 19? I do plan on pulling skier/tuber when the kids are a little older, and occasionally have a couple more adults on board.

Thanks,
-V

Re: Next prop size?

Keeping in mind I'm not an expert; I would stick with the size you have.You may be able to have it repaired and have them add a little cup.
Cupping should bring you to right around 4,800.If it presists in over reving
check that tach is accurate and throttle back to keep out of an over rev situation.
