"I have a 3.0 merc alpha 1. J
"I have a 3.0 merc alpha 1. Just replaced the engine with a running used one. After installing we started and timed. Engine sounded good. Installed outdrive yesterday and took to boat ramp and started on trailer. Engine vibrated violently and is making a clanking noise in the rear of the engine, I believe. What could this be? It just makes no sense, it sounded good without the outdrive on??? Please Help! Boat is sold and I want it to run properly before PU. Thanks for any suggestions?"
