I was cruising in 2-3 foot waves when my ski stalled out. Then it seemed like every bump I hit it would do it. Then it seemed like the ski was "bogging out" and would stall. I checked my impeller and it is clear of debris. I was thinking maybe my fuel filter or fuel pump but I'm not sure. I also lost about 20mph. But when I rev up my RPM'S are the normal 7500rpms. Someone please help!!
