Has anyone had trouble with the Fiberglass supports where the motor mounts are bolted? I had trouble this year with water and algie in the diesel fuel. I changed the filters after siphoning off the water and crud from the bottom of the tank. The boat ran fine after that but had a lot more vibration than usual, I had the fuel pumped out run thru filters and back into the tank. After changing the filters one more time, I had my diesel machanic take a look at the engine. I thought maybeI had a clogged injector. He said the engine was running fine but he noticed the fiberglass where the motor mounts bolt down was cracked and loose, causing the vibration. He just called me today, I haven't had a chance to look at it yet. If anyone has had any simular experience, suggestions would be greatly appreciated. Thanks Rich
