It is the boat owner’s responsibility to check for and replace damaged
parts due to galvanic deterioration. Refer to your Chaparral dealer to
investigate the source of stray corrosive currents.
Sacrificial anodes are installed on the outdrive and trim tabs to protect
underwater hardware on your boat. Metals used in sacrificial anodes are
less noble than the copper‐based alloys and aluminum used in
underwater fittings; therefore, the anodes will deteriorate first and
protect the more noble parts. Metals commonly used in sacrificial
anodes include aluminum, magnesium, and zinc.
The type of metal needed for your boat’s sacrificial anodes will depend
on your use of the boat. For instance, the type of water where you
commonly go boating is a major factor in determining your need.
Chaparral recommends you consult your dealer and your engine
manufacturer’s owner’s manual to determine the proper metal needed
in your sacrificial anodes.
Zinc anodes generally require replacement about once a year, but may
need to be replaced every six months in salt water areas. The need to
replace anodes more frequently may indicate a stray current problem
within the boat or at the slip or mooring. If zinc anodes are not replaced
annually, they may not be providing the necessary protection.
Note: Do not paint between the zinc and any metal it touches. Do
not paint over the zinc.
Placing a zinc in the water bonded to the metal outlet box on the dock
will reduce zinc loss on the boat. Do not connect this zinc to the boat’s
ground system.
Important: All electrically operated DC equipment and accessories
must be wired so that the ground
polarity of each device is the same
as that of the battery. Chaparral boats have a negative ground sys ‐
tem, which is recommended practice throughout the marine
industry. All metal items (fuel tanks, underwater hardware) in the
boat are connected to the zinc anode by the green bonding wire.


Verify the integrity of the boat’s entire AC shore power
grounding system, including the connection to the DC system
negative.

Verify that any galvanic isolators (if installed on your boat) meet
current American Boat and Yacht Council (ABYC) standards and
are fully functional.

Inspect shore power cords, adapters and boat receptacles for any
signs of deterioration, including cord wear, loose connections,
and signs of sparking or overheating and bent or pitted blades. If
there are any such signs, examine, correct, and test the
equipment or replace it.

Operate the boat’s electrical system at full load (everything on)
and check for AC system leakage or voltage between the boat’s
underwater fittings (bonded system, if equipped) and the shore
side AC system ground.
CAUTION: Replace sacrificial anodes if they are corroded 50% or more.
Galvanic Isolator
A galvanic isolator is installed in your boat and electrically connected
between the boat’s AC panel ground and the dockside AC ground wire.
The galvanic isolator is designed to permit AC ground currents to pass
safely between the boat and the dockside but to block the small DC
currents that flow in seawater between boats in a marina because of
different metals on the boats that are in the water. When the shore
power cord is connected to the boat and breaker, the green light on the
panel should be on.
