Active Corrosion Protection System
Your boat may be equipped with a Volvo Penta active corrosion protection system (APCS). This system operates
with very little current drain from the boat’s electrical system. It keeps the voltage potential in the area around the
drive unit in a range that is not corrosive to aluminum. If you do not have an active corrosion protection system
already installed, you may purchase one from your authorized Volvo Penta dealer.
NOTICE!
ACPS is designed for salt water applications only; using the system in fresh water–while harmless–will
not protect your sterndrive from corrosion.

The protection system’s control box has both red and
green LED indicator lights
A
. The lights will indicate the
amount of protection that the unit is providing to protect
the sterndrive and transom shield.
NOTICE!
The active corrosion protection system is
designed to adequately protect one drive unit from gal-
vanic corrosion under normal operating conditions.
This system will not provide protection from stray cur-
rents emitted by a malfunctioning AC power source on
your boat, the pier, or other boats in close proximity to
yours. Although the sacrificial anodes will last much
longer with this system, they must still be cleaned and
checked for material condition periodically.

indicates the unit is adequately
protected.

If the green and red LEDs
2
are illuminated, the
drive is protected but the system is drawing power
(between 3 to 150 mA) to protect the drive unit.
Check the conditions and solutions listed below.
