Replacement zinc anode
Sacrificial zinc anodes are mandatory when using a Kasco motor in salted, brackish or highly conductive water. Sold individually.
Each Kasco unit includes a sacrificial anode to help prevent corrosion and electrolysis. Kasco recommends that you replace the anode every year or sooner if it is more than 50% depleted or white in color.
Sacrificial anodes are available for 1/2 in. and 5/8 in. motor shafts.
Kasco recommends checking the anode at least every two to three months.
