Protection against
electrochemical corrosion
It is important that components submerged in the wa-
ter such as through-hull fittings, swim ladders etc. are
protected from galvanic corrosion. Our recommenda-
tion is to bond all of them to a transom mounted, pro-
tective anode, normally made of zinc. Trim tabs may
have their own protection.
NOTE! This bonding system with its individual com-
ponents should normally have no contact with the
negative circuit of the boat’s electrical system.
Local recommendations, e.g. ABYC, may state that
the battery negative terminal should be connected to
the bonding galvanic circuit. If you decide to connect
the bonding galvanic circuit to the battery negative
(–) terminal, you must also connect the engine block
with a cable large enough to carry the cranking en-
gine current, as described in ABYC chapter E-.
