Inspecting and Replacing the Anode
To prevent corrosion of the Sail-Drive body by sea or lake water, replace the anode every 100 hours of operation, once every six months or when it has reduced to half of the original volume (size). NOTICE: The anode of the Sail-Drive is only calculated for the Sail-Drive. Changing the material of the propeller may require additional anodes to be installed on the saildrive. SD20 (4) (2)
