Anti-Corrosion Protection
If the exhaust pressure readings are not as
described, clean or replace exhaust pressure fit-
tings.
Cleaning
Cleaning with

can dissolve carbon build-up.

through the fitting and allow it
to soak for four to six hours.
Use compressed air to blow through the fitting.
Limit the air pressure to 25 psi (170 kPa). Confirm
movement of air through fitting.
IMPORTANT:
Fitting does restrict air movement.
Replace exhaust pressure fittings that are
blocked and cannot be decarbonized.
Anti-Corrosion Protec-
tion
Sacrificial Anodes
Galvanic
corrosion occurs in fresh or salt water.
Salt, brackish, and polluted water can accelerate
corrosion. “Sacrificial” anodes are intended to pro-
tect the underwater metal components of the out-
board from galvanic corrosion.
Outboards are equipped with three sacrificial
anodes.
Visually inspect anodes and metal components
below water level. Erosion of anodes is normal
and indicates the anodes are functioning properly.
IMPORTANT:
Anodes that are not eroding may
not be properly grounded. Anodes and the mount-
ing screws must be clean and tight for effective
corrosion protection.
For best anode performance:
•
Replace all anodes that have eroded or disinte-
grated to two-thirds of their original size
•
Do not paint or apply protective coatings to
anodes or anode fasteners
•
Avoid using metal-based antifouling paint on the
boat or outboard.
