I recently de-winterized my 2006 VX 110. Everything worked fine for about an hour of running time. When I next went to ski, the throttle wouldn't power the ski above about 1/3 of normal speed. The sound of the engine is normal but subdued. With the boat on a lift, I cannot see anything blocking the intake area or propeller. If I squeeze the throttle while on the lift and running water through the cooling system, everything seems fine and the engine revs as it always has. The reving on the lift is significantly faster and more 'whiney' than when in the water. Can anyone suggest what more I can check before getting out the trailer and taking it in to be serviced. I've also tried fresh gas and a bottle of STP injector and carb cleaner.
Thanks.
Thanks.
