VI ANODE REPLACEMENT
To minimize galvanic corrosion, the SD-10 system has a sacrificial anode placed on the foot of
the sail drive.
However, in particularly adverse conditions we recommend the use of additional anti-
corrosion anode kit, to be installed separately.
The anodes provide protection against corrosion under normal use.
Remove propeller.
