The port side exhaust over heated and melted the rubber connector. As stated on a previous thread in here nothing else was hot. I checked the water pump flow and it is OK, I pulled the hose leading to that exhaust checked flow with my house hose and it seemed to be OK (water flowed out and over exhaust elbow). The exhaust elbow seems to be gnarly (all crudded up and i dont think the water is flowing correctly). Could this be the reason for the over heat? How should the water flow over elbow? Someone on here said i needed to replace both manifolds and elbows. If it is a problem with the exhaust elbow water flow can i just replace that one for now? Dont really have the cash right now to replace both sides but i would like to get the boat out some more this season. If it is critical that both sides be replaced i will park boat and look for next season. Any advise would be appreciated, Thank you.
