Specs At A Glance

Good To Know

Q: How often should I inspect the anode? A: Inspect the anode during every oil change or at least every season, and replace it when it has corroded to about half its original size.

Q: Is this anode suitable for freshwater use? A: Zinc anodes are best for saltwater, but they can also be used in brackish water; for freshwater, a magnesium anode is often recommended.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
