My question relates to a 1989 Chevrolet OMC 4.3l King Cobra. The drive is OMC.

I am currently winterizing both engines. While running the Starboard engine I noticed for the first time a rattle coming from the front of the engine.

It seems to be either the Alternator bearing, the water pump or (I hope not) the centre of the engine closer to the front.

Any advice would be appreciated.
