Hi David, I have the same engine and transmission. Back in 2008, I felt a lot of vibration through the cockpit floor when the engine was on. It actually made the cockpit floor panel rattle if I wasn't standing on it. I ordered new engine mounts at the advice of a diesel expert, but the real cause turned out to be the exhaust hose resting on the stringer running across the boat at the rear of the engine. It was a simple fix to loosen the clamps holding the exhaust hose and slide it and the lift muffler aft enough so the hose no longer touched the rib. I probably moved it an inch. (I never installed the new mounts but keep them at home.) I'd suggest checking your engine's exhaust hose is not resting on that rib
