Thanks, we have that transmission on it now. And we have optimized the prop, I think I am running a 13 X13. Boat is running great. The 72C i had a line on was rebuilt at $1,350.00. I know new would be a lot more. I am going to play around looking for a solution that has the same dimensions. I would just like to know the options. Cost is certainly a consideration. Boat does fine for my old bod skiing at 34 mph. I probably couldn't pull a strong skier at 36, but those guys are all skiing behind newer boats.
