I put 2000hours on my old 1994 701 wave raider. I bought it in 1996 and sold it in 2004. I rebuilt the motor twice only put in new pistons and rings on the same crank. The only time it broke down was when the spline wore out , due to jumping to many waves and vibration from riding it hard. It was so reliable i hired it out to a friend of mine who use to hire skis, got a free trailer out ot it.
The reason i put 2000 hours on it was i had a hourly tiny tach on it. GREAT SKI.
