faulty DC wiring or from a marina pier, piling or dock carrying leaking
marina ground wiring such as a dockside cord partially submerged.
GALVANIC/STRAY CURRENT CORROSION
Cause/Observed Condition
Corrective Action
Sacrifi cial anodes consumed
Replace anodes when 30%
consumed
Sacrifi cial anodes not grounded
to drive
Remove anodes, clean contact
surface, reinstall, check for
continuity
Loss of continuity between
underwater parts & ground
Provide good ground connec-
tions
Nearby vessel with stray current
Contact appropriate personnel
Remove your vessel from water
Paint on drive heavily worn,
exposing more metal
Prime and repaint or install ad-
ditional anodes
Sacrifi cial anodes painted
Remove paint or replace anodes
Drive tilted/anodes out of

Corrosion in area of exhaust
outlets
Remove deposits
Corrosion occurring after vessel
is removed from saltwater
Wash exterior and fl ush interior
with freshwater
Stainless steel parts corroding
Clean parts, remove foreign
