Freezing Temperature Operation
IMPORTANT: If the boat is operated during periods of freezing temperature, precautions
must be taken to prevent freeze damage to the power package. Damage caused by
freezing is not covered by Mercury MerCruiser 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 come into
contact with your power package. Components on your engine will be damaged if
submerged. Damage caused by submersion is not covered by the Mercury MerCruiser
Limited Warranty.
Basic Boat Operation (DTS Models)
Launching and Boat Operation
IMPORTANT: Install bilge drain plug prior to launching boat.
!
CAUTION
To avoid possible ingestion of water that can damage engine components, do not turn
the ignition key off when the engine is above idle speed. When launching your boat from
a steep ramp, enter the water slowly. Do not use the lanyard stop switch to shut off the
engine above idle speed. When coming off plane, if a large following wave may roll over
the boat's transom, apply a short, light burst of throttle to minimize the wave action against
the stern of the boat. Do not come off plane quickly and then shut off the engine. Also
avoid shifting into reverse while on plane.
