My Craz came with the OJ 945 as the upgraded Surf Prop. I never really loved it then i hit something and bent it. I decided to replace it (still havent had it repaired) with an Acme 1235. Lost a marginal amount of hole shot, surfs about 200-300 RPM lower (quieter) and picked up 2mph up top, but runs MUCH smoother and quieter in my opinion. I've had a bunch of Acme props and only one OJ, and I'll stick with Acme for my money!
