I have about 1500lbs of ballast in my boat. The OJ is a 13x13 4b prop. It was a bit slow out of the hole and did/does not hold speed very well.
The Acme is a 13x11.5 3b. Better holeshot and better speed holding.
Top end is about the same with the two, the Acme is actually a bit faster. The OJ is a good prop, I think that it's pitched to high for my boat and load (Cal-Air, 1500lbs plus people)
I'm thinking about seeing if I can get the OJ pitched down to 12 instead of 13 to see if works better.
