Last week, my gal friend was riding her GTI LE, was idling, then accelerated and a god-aweful noise came out of the thing...engine was still running but she did not move. I figured she sucked up a stick or? into the impeller. I towed her back to shore, checked and nothing was in the impeller. Maybe when I was towing her, it came out but now the engine runs and still a god-aweful noise when accelerating, no move the boat. Looks like the spline in the counter weight behind engine or the impeller shaft spine stripped out??!! how could that happen by a stick getting into the impeller?? ever heard of this happening? I have not torn it apart, but you can move the counter weight (?) on the back of the engine and the shaft does not move. I am a rookie to the Seadoo world, can this spline strip out? a Yamaha guy said he heard of a grease bladder blowing out, and could cause the loss of connection...true, the cover is plastered with grease. There is a zerk fitting there, so whats the deal? easy fix? Any ideas out there??
