ypvs servo motor question 1300r
i need to know what are the probable causes of the servo not opening the valves completed when operating the ski on the water at full throttle.
when we star and immediately stop the engine it will cycle perfectly. we mark the servo closed and fully open , to keep track on the rotation.
also we notice as we ride that the minimum bounce will make the servo cycle .it closes and reopen about a quarter of turn..
as we ride with the servo connected the engine only gets around 6k rpms. if we disconnect the servo and opened manually the engine rpms gets up in the 7k.

Check you electrical circuit and cabling, that open-close cycle should not occur during slow speeds.
Place wave-eater clips and connectors to make sure all 3 valves open fully.
You can adjust the PV cables. check if the servo pulls it completely open.

cables out of adjustment will cause the PV motor to keep cycling and usually stop. If you have slug and carbon buildup on the power valves causing them not to fully open or close can result in the same.
