Exterior Care; Fuel System - Mercury 4 Manual

The anode requires periodic inspection especially in salt water which will accelerate the erosion. To maintain this
corrosion protection, always replace the anode before it is completely eroded. Never paint or apply a protective
coating on the anode as this will reduce effectiveness of the anode.

Exterior Care

Your outboard is protected with a durable baked enamel finish. Clean and wax often using marine cleaners and
waxes.

Fuel System

Avoid serious injury or death from gasoline fire or explosion. Carefully follow all fuel system service instructions.
Always stop the engine and do not smoke or allow open flames or sparks in the area while servicing any part
of the fuel system.
Before servicing any part of the fuel system, stop engine and disconnect the battery. Drain the fuel system
completely. Use an approved container to collect and store fuel. Wipe up any spillage immediately. Material used
to contain spillage must be disposed of in an approved receptacle. Any fuel system service must be performed in
a well ventilated area. Inspect any completed service work for sign of fuel leakage.
FUEL LINE FILTER
Inspect the fuel line filter. If the filter appears to be contaminated, remove and replace.
IMPORTANT: Visually inspect for fuel leakage from the filter connections by squeezing the primer bulb until firm,
forcing fuel into the filter.
FUEL LINE INSPECTION
Visually inspect the fuel line and primer bulb for cracks, swelling, leaks, hardness, or other signs of deterioration
or damage. If any of these conditions are found, the fuel line or primer bulb must be replaced.
