Help with loud clunking sound under load. Only happens in forward, not reverse
This started after I rented the boat to a Airbnb guest. There’s a chance they used the wrong mixture of gas and oil. I took it to my mechanic. He had someone take the engine apart and replaced a sprocket for $1,900, possibly the front sprocket. The clunking didn’t go away, but it did change sound slightly. The engine has the same power, it can go for 15 minutes no problem. The sound doesn’t happen in reverse which makes me believe that it’s fixable. Please help me figure this out!!! I appreciate it.
