IMPORTANT: Cummins MerCruiser Diesel strongly recommends that this service
should be performed by an authorized Cummins MerCruiser Diesel dealer /
distributor. Damage caused by freezing IS NOT covered by the Mercury MerCruiser
Limited Warranty.
Seawater 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. Damage caused by freezing is NOT covered by
the Cummins MerCruiser Diesel Limited Warranty.
IMPORTANT: Cummins MerCruiser Diesel recommends that propylene glycol
antifreeze (a nontoxic and environmentally safe) antifreeze be used in the seawater
section of the cooling system for cold weather or extended storage. Ensure that the
propylene glycol antifreeze contains a rust inhibitor and is recommended for use in
marine engines. Follow the propylene glycol manufacturer's recommendations.
