Help - have a high pitched whine with vibration on front casing on my 1993 GPX Seadoo, 3 seater.  I was stranded on the lake yesterday. The engine was rebuilt about 8 years ago. Also. does anyone know if the outpost driveshaft at rear engine turns at the same speed  as the engine crankshaft or is there a clutch. I am not mechanically inclined but I have a nephew who is.  Any help or suggestions would be greatly appreciated. DF
