Corrosion Control Anodes
NOTICE
Anodes made of insufficiently pure aluminum alloys may not adequately protect critical drive components from corrosion. We
recommend using anodes sold through Mercury Precision Parts only.
Anodes help protect the power package against galvanic corrosion by sacrificing its metal to be slowly eroded instead of other
metals.
This model has three corrosion control anodes: One on the bottom of the nozzle, one on the reverse gate, and one under the
rudder. Anodes help protect the Mercury Jet Drive against galvanic corrosion by sacrificing its metal to be slowly eroded instead
of the Mercury Jet Drive metals.
a - Anodes
All anodes require periodic inspection, especially in saltwater. Inspect anodes periodically (refer to the Inspection and
Maintenance Schedule). Replace any anodes before they are 50% corroded. Never paint or apply protective coating on the
anode, as effectiveness of the anode will be reduced.
Bilge Siphon Inspection
Inspect the bilge siphon system at periodic intervals to ensure maximum performance.
a - Siphon break
b - Bilge hose
c - Bilge water pickup screen
1. Inspect the pickup screen for foreign material. Clean if necessary.
2. Inspect the hole in the siphon break for blockage. Clean with a small wire if necessary.
3. Ensure that the siphon break is secured above the waterline.
