I need help. I have a 1996 Sea doo GTX. The rubber connection hose between the muffler and the exhaust manifold has split twice on me. I am thinking there is a blockage in the muffler or the 3 inch rubber exhaust hose to to the stern of the boat. Is the muffler hollow or is it baffled? How much back pressure should there be? Is there a way to check it? Is there something else that can cause this problem. The ski has no cooling issues and the pump appears clear. The way I found the problem was the engine was running ruff and would not get up to top RPM. The engine was sucking in exhaust fumes. Any suggestions would be helpful.
Thanks... Tim
