•
At the end of each daily operation, completely drain the seawater section of the cooling system to protect against damage
by freezing.
•
At the end of each daily operation, drain the water from the water separator, if equipped. Fill the fuel tank at the end of daily
operation to prevent condensation.
•
Use the required permanent‑type antifreeze solution to protect components against damage by freezing.
•
Use proper cold weather lubrication oil; ensure that the crankcase contains a sufficient amount.
•
Make certain that the battery is of sufficient size and is fully charged. Check that all other electrical equipment is in
optimum condition.
•
At temperatures of –20° C (–4° F) and below, use a coolant heater and a marine application bilge air heater to improve cold
starting.

Protecting People In The Water
While You Are Cruising
It is very difficult for a person in the water to take quick action to avoid a boat heading in their direction, even at slow speeds.
Always slow down and exercise extreme caution any time you are boating in an area where there might be people in the water.
Whenever a boat is moving (even coasting) and the gear shift is in neutral, there is sufficient force by the water on the propeller
to cause the propeller to rotate. This neutral propeller rotation can cause serious injury.
While Boat Is Stationary
A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers.
Stop the engine immediately whenever anyone in the water is near your boat.
Shift into neutral and shut off the engine before allowing people to swim or be in the water near your boat.
High Speed and High Performance
If your boat is a high‑speed or high performance boat with which you are unfamiliar, we recommend that you never operate it at
its high‑speed capability without first requesting an initial orientation and demonstration ride with your dealer or an operator
experienced with your boat. For additional information, refer to the High Performance Boat Operation booklet
(90‑849250‑R2) from your authorized Mercury Diesel repair facility.
Passenger Safety In Pontoon Boats and Deck Boats
Whenever the boat is in motion, observe the location of all passengers. Do not allow any passengers to stand or use seats
other than those designated for traveling faster than idle speed. A sudden reduction in boat speed, such as plunging into a
large wave or wake, a sudden throttle reduction, or a sharp change of boat direction, could throw them over the front of boat.
Falling over the front of the boat between the two pontoons will position them to be run over.
Boats Having An Open Front Deck
No one should ever be on the deck in front of the rail while the boat is in motion. Keep all passengers behind the front rail or
enclosure.
