Anodes
Sacrificial anodes are attached to the bottom of the
transom shield A and on the rear of the drive B.
A correctly working anode will slowly erode away. They
require frequent inspections to make sure there is
enough anode material left to protect the shield and
drive.
Anodes that are taken in and out of the water (e.g trailer
boats) will develop surface scale or oxidation. This
must be removed, with sandpaper, for the anode to
function.
Do not paint anodes, the paint will block the galvanic
action, preventing the anode from working correctly.
Anodes purchased from your Volvo Penta dealer meet
the highest specifications for material composition and
purity. Some aftermarket anodes may not meet these
quality specifications.
Inspecting Drive Anodes
Inspect anodes frequently, especially if the boat is
stored in the water. See Owners Checklist.
If an anode is half its original size replace it. The
amount of erosion on the drive anode is a good
indication of the condition of the shield anode.
If additional electronic or electrical equipment is
installed, each item should have an individual anode
or grounding device and all grounding devices must be
interconnected. Follow equipment manufacturers
recommendations.
Anode Replacement Information
NOTICE! Your Volvo Penta product has been shipped
with Aluminum anodes
Aluminum works best in salt or brackish water and is
also a good choice if the boat is used in different or
unknown salinity conditions.
Magnesium anodes are available for freshwater use.
Zinc anodes are available if the boat will only be used
in saltwater.
See your dealer for replacement anodes.
