so I have a 1996 glastron 195 sx. I took boat out and it overheated. And fried exhaust bellows. I took Sea Water pump apart...impeller was shot. I replaced. Now I hook earmuffs up and get no flow. I then took thermostat apart...made sure it was working...I push the springs flapper was stuck but it moves now. Put thermostat back in. Hooked it up to hose and earmuffs again...ran boat up above 200... No water flow out of exhaust. Where do I start? :redface:
