Exterior Care; Fuel System - Mercury 4C Instruction Manual

The anode requires periodic inspection especially in saltwater
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

Fuel is flammable and explosive. Ensure that the key switch is
off and the lanyard is positioned so that the engine cannot
start. Do not smoke or allow sources of spark or open flame in
the area while servicing. Keep the work area well ventilated
and avoid prolonged exposure to vapors. Always check for
leaks before attempting to start the engine, and wipe up any
spilled fuel immediately.
Before servicing any part of the fuel system, stop the 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.
