Better holeshot

[fireblade929]

Hi all, I have a 1985 Yamaha 140 on the back of a magnum 1600 ski boat. I am currently running a 21" yamaha 3 blade painted stainless prop. The boat does 55mph@5700rpm with this prop setup, without a skier which I am relatively happy with. With a skier onboard the top end is still good but lacks out of the hole punch with a heavier skier starting on a slalom ski. I'ts like the prop isn't grabbing the water all that well. I'd like to stay with a 21" setup as I've played around with 17" etc to get out of the hole better but the thing revs like crazy. Even with the 17" standard yamaha prop it still seems to lack good grab. I'm after a good 21" or even 19" polished stainless setup which has good "out of the hole" qualities. I'm thinking a 4 blade system may be the way to go. Any suggestions?

Re: Better holeshot

Merc High5 gives great results for watersports.
Merc Revolution 4 is also good along with Stilleto's Bay Pro II.
Careful with the pitch of the Rev 4 though as its somewhat aggressive.

Merc has a good prop selector website giving recomendations as to type and pitch.
