Cosmetic Care & Maintenance
e vessel should be tested every couple of weeks to determine the
integrity of the anode protection system. If not installed, Volvo and
Mercury o er an optional corrosion protection system that utilizes
the anode/cathode theory to assist in o setting galvanic corrosion.
Another way to test the system is to measure the hull potential. is
is accomplished by immersing a reference electrode, usually a sil-
ver/silver chloride into the water about six inches behind the drive.
With leads attached to a digital multi-meter the hull potential is read
on the DC scale and compared to recommended speci cations for
the water body type. See the owner's information vendor packet for
more information or contact your nearest authorized Regal dealer.
Tips To Aid In Maintaining Galvanic Integrity
1. Test the galvanic integrity of your vessel every 2 weeks. Trim the
stern drive/outboard and inspect anodes/parts for signs of galvanic
corrosion, stray current corrosion or loose fasteners. Contact your
closest Regal dealer/marine professional for further information.
2. Never paint over anodes as they will become inoperative. Always
leave at least one inch between bottom paint and any underwater
tting such as seacocks, swim platform stanchions and all drive and
propulsion related underwater parts.
3. Periodically remove vessel from water and clean/pressure wash
all outdrive, anode and hull bottom areas to remove growth.
4. Ensure vessel is using the correct anode metal for the body of
water that it is moored. See the engine/drive manufacturer informa-
tion packets for more information or contact an authorized dealer.
5. Ensure that the drive is completely "in" down to provide more
complete anode protection when vessel is moored.
6. Do not attempt to use magnesium anodes in saltwater. ey will
provide overprotection.
