@hayden, so what RPM are you running now while surfing? I was wondering the same thing when i was fully loaded (4k, +1k lead, +700 people) the other day and it was 3900-4100 rpm at 11.2-11.3 mph at 2500' same boat as yours

i have the oj 15.5x15 altitude prop from the factory.

And according to Drew Tinker, the lower pitch props are more for hole shot speed while wakeboarding and having a higher pitch prop pushes more water for surfing, hence why the moomba website has the higher speed/pitch prop listed a surf prop.

yet everything i read/research says lower pitch is needed for surfing.
