Freezing Temperature And Cold Weather Operation
IMPORTANT: If boat is operated during periods of freezing temperature, precautions
must be taken to prevent freezing damage to power package. Damage caused by
freezing IS NOT covered by Cummins MerCruiser Diesel Limited Warranty.
CAUTION
Seawater (raw water)
section of cooling system MUST BE COMPLETELY drained for
winter storage or immediately after cold weather use, if the possibility of freezing
temperatures exist. Failure to comply may result in trapped water causing freeze
and/or corrosion damage to engine.
In order to operate the engine in temperatures of 0 degrees C (32 degrees F) or lower,
observe the following instructions:
•
At the end of each daily operation, COMPLETELY drain seawater section of cooling
system to protect against damage by freezing.
•
At the end of each daily operation, drain water from water separator, if equipped. Fill fuel
tank at end of daily operation to prevent condensation.
•
Use required permanent-type antifreeze solution to protect components against
damage by freezing.
•
Be sure to use proper cold weather lubrication oil, and be sure 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 degrees C (–4 degrees F) and below, it is recommended that
you use a coolant heater to improve cold starting.
•
If operating in arctic temperatures of – 29 degrees C (–20 degrees F) or lower, consult
your Cummins MerCruiser Diesel dealer / distributor for information about special cold
weather equipment and precautions.
Refer to
Section 6
for Cold Weather or Extended Storage related information and draining
instructions.

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 Cummins MerCruiser
Diesel Limited Warranty.
