NOTE: On some sea water cooled models the oil cooler and after cooler are fitted with sacrificial zinc anodes (pencils) that are located in the end bonnets of the coolers. These sacrificial zinc anodes should be checked after the first 50 hours of operation to determine if corrosive conditions exist. If satisfactory this interval may be extended to 500 hours.

Is sacrificial zinc anode 50% corroded?

Coastal/harbour waters can contain corrosive chemicals from pollution and may reduce anode/cooler life.

Effects of corrosion or erosion are specifically excluded from warranty considerations.
