To minimize electrolytic corrosion of the metals on
your boat, zinc anode plates are provided to protect
underwater hardware. Zinc, being much less "noble"
than the copper-based alloys and aluminum used
in underwater fittings, will deteriorate first and protect
the other metals.
Stern drives are fitted with zinc anodes on their lower
units (refer to your Engine Owner's Manual for their
locations).
Zinc anodes require replacement about every six
months if the boat is operated in salt water. In fresh
water, the zinc anodes can be replaced about once
a year.
If the anodes deteriorate more rapidly than this, there
is probably a stray current problem within the boat
or at the slip or mooring.
If the anodes do not deteriorate, they are not
protecting the other metallic parts of your boat. This
can be caused by loose anodes or by low grade
zinc or by not having a solid electrical contact
between the anode and the metal it contacts, or by
paint on the anode.
If the anodes are deteriorating rapidly, or not at all,
contact your dealer.
NOTICE
DO NOT PAINT BETWEEN THE ZINC AND THE METAL
IT CONTACTS, AND DO NOT PAINT OVER THE ZINC.
