3.6 Bonding System
Your boat is equipped with a comprehensive metallic bonding system
that interconnects all underwater equipment and thru-hull fittings. The
bonding system ensures that the “cases” of all metallic equipment
onboard your boat, including the fittings, are at the same electrical
potential. This minimizes corrosion of the underwater fittings caused by
stray electrical currents.
Included within this bonding system are sacrificial zinc anodes that have
been installed on each of the boat’s propeller shafts and onto the under-
water portion of the boat’s transom. These anodes corrode and deterio-
rate before the boat’s underwater fittings and provide a visual reference
to the level of stray current to which your boat is being exposed.
Your boat’s 12-volt DC electrical system, AC electrical system, and the
batteries’ negative leads are all connected to the bonding system through
buss bars. The buss bars are located in the engine room and bilge area
and are connected to the transom-mounted zinc plate.
Do not tamper with or modify the boat’s bonding system. Doing so could
threaten the integrity of the system.
Monitor the condition of your boat’s zinc anodes. Replace the zinc an-
odes when they have deteriorated to 50% of their original size. Do not
allow the zinc anodes to completely deteriorate. Refer to “7.1 Mainte-
nance Schedule” for recommended inspection intervals.
NOTE: Damage resulting from stray current or galvanic corrosion is NOT
covered under the Carver limited warranty.
