TIA for any help/suggestions.

There should be a name plate on the engine (in the area where the belts are), might need to wipe the area with rag to find it. The name plate should state model and serial number. There should be a name plate also on the transmission (oposite side from where belts are). 3GMD is a direct sea water cooled 3 cylinder Yanmar. Check the pic, name plate is hard to see but is the green/silver rectangle between the belts, just above the place where a hand crank would go.
