ok last year on my last trip o
ok last year on my last trip out i started to hear a clacking noise from the back of my inboard 120hp motor i think it is a 4.3L merc. I have not had a chance to get to it since I went to winterize it. When i was running the motor with just the hose i could not hear the sound. But i remember distinctly the sound it was making on the lake. From what i have read here it could be the exhaust flapper...could it be anything else? Also it is ok to run without changing the exhaust flapper?
Thanks in advance
