Took my 75 HP Mercury outboard four stroke in for a oil change. Decided to replace fuel sender at the same time. Marina keep it for about a week. It rained all week. Got boat back and within 1hr boat was dead. Bogged down. marina towed it back in. After about five day they accepted responsibility and repaired the the water filled engine. Now, I get my boat back and the engine vibrates and kinda clanks when I shift from neutral just into forward. So I took it back to marina. They said they put it back together wrong. They again fix it. (right). I picked the boat back up yesterday and again the same thing but worse. Shift from neutral to just in to the forward position and the motor shakes and vibrates the whole back of the boat. If any one can give me a idea of what might be going on so I can feel like I know what I am talking about. I would appreciate it. Thanks
