Zinc Anode for AquaThruster
Weeders Digest recommends replacement of the Aqua Thruster's zinc anodes every year - or sooner if anode is more than 50% depleted.
A zinc anode is easy to replace on the shaft of all Aqua Thruster motors.
This Zinc Anodes works with all 1/2 hp - 3/4 hp - 1 hp Aqua Thrusters
AquaThruster Zinc Anodes are necessary for protection from corrosion due to electrolysis. The zinc anode should be inspected regularly and replaced if reduced to half of its original size or if white in color.
Corrosion from electrolysis is more commonly associated with saltwater or brackish water, but as a matter of precaution it is important to periodically check the zinc anode in all installations (at least every two to three months)
