Does anyone know the recommended CCA for the Yanmar 2GM? The factory mechanic’s manual I have at home goes into more detail than I can understand but doesn’t give me anything that simple. The owner’s handbook is on board and I was hoping to bring the new battery with me the next time I visited the boat.
Torresen Marine (Marine Diesel Direct) advised me that the starter motor would draw about 90 amps on our Universal 32 hp diesel. It''s four cyclinders, and I think about 100 cubic inches.
We put in a Optima blue top 1,100 CCA battery and love it.
Amen on the Optima Blue top. They are great. One of the most rugged starting batteries made. You''ll find them in many military vehicles. The sprial technology makes them very popular becuase they are less prone to shock (as in G forces) damage.
