CHAPTER 7

The vessel should be tested every couple of weeks to determine the

integrity of the anode protection system. If not installed, Volvo and

Mercury offer an optional corrosion protection system that utilizes

the anode/cathode theory to assist in offsetting galvanic corrosion.

Another way to test the system is to measure the hull potential. This

is accomplished by immersing a reference electrode, usually a silver/

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 speciﬁ cations for the water

body type. See the owner’s information vendor packet for more infor-

mation 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. Raise the outdrive

and inspect anodes/parts for signs of galvanic corrosion, stray cur-

rent corrosion or loose fasteners. Contact your closest Regal dealer/marine

professional where signs of galvanic corrosion exist.

2. Never paint over anodes as they will become inoperative. Always

leave at least one inch between bottom paint and any underwater ﬁ t-

ting 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 wa-

ter that it is moored. See the engine/drive manufacturer information

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. They will

provide overprotection.
