Is there an anode that needs to be inspected and / or replaced on the seawater side of the cooling system. I have reviewed my engine operation manual, however, I cannot find an anode listed for periodic inspection. Yanmar 3YM30 thanks for your response

no-

Yanmar only used sacrificial anodes on raw water cooled engines-yours has a fresh water/antifreeze loop in the engine, the raw water only goes thru the impeller pump and the heat exchanger
