Anyone out there have this model boat. I've been having some performance issues and I'm curious to get some comps. from an owner who has the same boat. I've just recently put on a 13 x 12.5 oj 3 blade.

Post some pics of your engine?? I had a factory 454 in a previous boat.

Was that the prop OJ recommended?

What specifically are the performance issues you have been experiencing.?

Eric recommended this prop after I told him I was looking for a strong hole shot with the boat pretty well loaded. Took her out the other day with about 800 lbs worth of passengers and gear and boat didn't seem to plane. Top end about 31 mph wot. I'm having a tach problem that needs attention so I don't have an accurate reading there. From dead stop to 20 mph was 7 second.

Maybe you've got some engine issues? Did you check spark plugs, cap, rotor, ignition timing, secondaries on carburetor, fuel pump pressure?

Alot of things could cause your boat to have bad performance, not just the prop.
