Galvanic Isolator
The galvanic isolator is located in the cabin, behind the
AC/DC panel.
Stray, low voltage current flowing between the AC safety
ground and DC bonding system is a principal cause of
“galvanic” action. This type of stray current will normally
overload your zinc anodes as they try to protect your boat
from other near by boats and/or metal objects of the
marina. Sacrificial zincs corrode away as they protect
metal thru hulls, shafts and props from damaging galvanic
corrosion and electrolysis.
Installing the galvanic isolator between the AC safety ground and DC bonding system interrupts the galvanic
circuit with other boats and the dock when your boat is plugged into a shore power system. It also maintains
an AC safety ground and solves the most common cause of corrosion. Corrosive action on your zincs is
significantly reduced while the integrity of the critical safety ground path is maintained. This means a
significant savings in boat haul out fees and zinc replacement costs.
The sacrificial zincs are located on the trim tabs and engines. The zincs should be checked periodically
and changed when needed.
Bonding System
All metal components that have water either going through them or touching them are bonded to the zinc
anodes on the transom of the boat. The zinc anodes should be checked periodically and changed when
needed.
