My 1997 GSX fills with water in a matter of minutes while riding. Sitting in the water with engine off it is fine. I have tried filling the engine compartment with fresh water (not too high) to see if there is a shaft seal leak or even a breech in the hull. Results were negative. I am beginning to think the bilge drainage system is blowing water into the engine compartment while the impellor is spinning. Has this ever happened? Can I plug the bilge system for a few runs to see if that is the problem? In reading my shop manual it sure appears like it could be. Any thoughts Karl?
