"After having the engine coupler replaced on an 1989 Mercruiser 120HP 2.5L engine, I started hearing a light knocking or clicking sound coming from the engine block area. As the RPMs increased (whether engaged or not), the clicking sound would speed up. After 2 hours of use, the clicking got louder. After 4 hours of use the clicking got really loud until the engine just stopped. I could not turn over the engine. What could the issue be? Are there any issues that could come up from not lining up the engine properly when re-installing the engine that could produce this result?"
