B. Galvanic Corrosion
Galvanic corrosion results from a potential electri cal
difference existing between dissimilar metals im-
mersed in a conductive solu tion (e.g., salt or brackish
water). If these metals touch or are otherwise electri-
cally connected, this potential difference produces an
electron flow between them. The attack on the more
active metal is usually in creased and the attack on the
less active metal is decreased, as compared to when
these metals are not touching.
C. Corrosion Prevention
Anti-corro sion an odes are attached to the bottom of
the gimbal housing to prevent corrosion to your stern
drive and underwa ter parts. These anodes will be
slowly eroded away by galvanic action and require
periodic inspection. Please refer to the section on
“Anti-Corrosion Anodes” or “Corrosion and Corrosion
Protection” in your engine manufacturer’s manual for
additional information. The engine manual is included
in the owner’s packet.
