Corrosion Control Anodes; Battery Inspection - Mercury 200 Sport-Jet Operation & Maintenance Manual

Corrosion Control Anodes

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.
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 their
metal to be slowly eroded instead of the Mercury Jet Drive metals.

All anodes require periodic inspection, especially in saltwater. 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.

Battery Inspection

The battery should be inspected periodically to ensure proper engine starting
capability.
IMPORTANT: Read the safety and maintenance instructions that accompany
your battery.
1. Turn off the engine before servicing the battery.
2. Ensure that the battery is secure against movement.
3. Battery cable terminals should be clean, tight, and correctly installed.
Battery cables must be connected with the correct polarity (positive to
positive and negative to negative).
4. Ensure that the battery is equipped with a nonconductive shield to prevent
accidental shorting of battery terminals.
