NOTICE
Water trapped in the seawater section of the cooling system can cause corrosion or freeze damage. Drain the seawater section
of the cooling system immediately after operation or before any length of storage in freezing temperatures. If the boat is in the
water, keep the seacock closed until restarting the engine to prevent water from flowing back into the cooling system. If the boat
is not fitted with a seacock, leave the water inlet hose disconnected and plugged.
NOTE: As a precautionary measure, attach a tag to the key switch or steering wheel of the boat reminding the operator to open
the seacock or unplug and reconnect the water inlet hose before starting the engine.
In order to operate the engine in temperatures of 0° C (32° F) or lower, observe the following instructions:
•
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 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 to improve cold starting.
• If operating in arctic temperatures of –29° C (–20° F) or lower, consult your Cummins MerCruiser Diesel Authorized Repair
Facility for information about special cold weather equipment and precautions.
See
Section 6
for cold weather or extended storage related information.
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, a bilge pump, or both a drain plug and a bilge pump. Install the drain plug and check the operation of the bilge pump,
if equipped, before putting the boat in the water.
Check these items on a regular basis to ensure that the level of water 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 Cummins MerCruiser Diesel Limited Warranty.
Protecting People in the Water
While the Boat is Moving
A person in the water may find it very difficult to take quick action to avoid a boat heading in their direction, even at slow speeds.
21604
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 the Boat is Stationary
!
WARNING
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 engines before allowing people to swim or be in the water near your boat.
Do not allow people to swim around the boat with the Skyhook Electronic Anchor engaged. The Skyhook Electronic Anchor causes
the drives to move and the propellers to turn without notice. Having the engines in neutral does not protect the swimmers.
Swimmers in the area of the propellers are at risk of getting injured.
