Is this Jerry McConells old boat Clifford?
I would say it's the 6 blade props. Very hard on the drivetrain and in that set up the upper gears in a 6 would be the weakest point. Just went through the same thing with 700 Nxt set up. Merc said get rid of the 6 blades to make the transmissions and drives live.

How deep in the water the drives/props are and the 6 blades are going to be the big killers. High X and 6 blades are hard on drives. Drive guardians may help depending how much the boat comes out of the water.

Yes this is Clifford. And that's what Russ was thinking about doing but just wanted to get a little more insite on it.
