I have the OJ 14.25 x 14 wakeboard prop on my '08 Supra with the 340 CAT ETX motor, this combo works very well for maximum torque. I can get on plain very quickly with a load of people and 1200-1900 lbs of ballast. Only downfall is the max speed is about 40 mph, but I rarely go over 30 anyway.... would rather have the holeshot and torque.
Thumbs up from me for this prop.... IMO well worh the $$$. They are having a group buy through June at Nettle Props, I believe you can pick up the ACME Edge 14.25 x 14 for around $440 which is a great price. I just picked a spare Edge up with the ACME prop pulling kit/case, very nice set up. Call JT at Nettle Props, he is great to deal with, they will take care of you.
