OPERATION
49
Flush cooling system if in saltwater area.
Freezing Temperature Operation
IMPORTANT: If boat is operated in freezing temperatures, ensure
that closed coolant is rated for the temperature range in which it is
to be used. The seawater section of the engine must be drained
after use to prevent freezing. Damage caused by freezing is not
covered by Mercury Racing's Limited Warranty.
Drain Plug and Bilge Pump
The engine compartment in your boat is a natural place for water
to collect. For this reason, boats are normally equipped with a drain
plug and/or a bilge pump. It is very important to check these items
on a regular basis to ensure that the water level does not rise to
come in contact with your power package. Engine components will
be damaged if submerged. Damage caused by submersion is not
covered by the Mercury Racing Limited Warranty.
The bilge drain can be used to change crankcase oil. Refer to the
Maintenance
section.
Launching And Boat Operation Care
NOTICE
Some boating maneuvers can introduce water into the engine
through the exhaust system, causing severe engine damage. Be
careful when unloading a boat from its trailer, slowing down
rapidly, backing up rapidly, and stopping suddenly.
In any of the situations described in the preceding caution, water
entering the engine could cause severe damage to internal parts.
