CLOSED COOLED (COOLANT) MODELS
The following information outlines the procedures for draining the seawater section of the
closed cooling systems.
IMPORTANT: Drain seawater section
of closed cooling system only.
CAUTION
If boat is to remain in water after draining, seawater inlet hose must be removed and
plugged to prevent a siphoning action that may occur allowing seawater to flow
from the drain holes or removed hoses.
IMPORTANT: Boat must be as level as possible to ensure complete draining of cool-
ing system.
CAUTION
Seawater section of cooling system MUST BE COMPLETELY drained for winter
storage or immediately after cold weather use if the possibility of freezing tempera-
tures 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
Mercury MerCruiser Limited Warranty.
IMPORTANT: Closed cooling section must be kept filled year-round with recom-
mended coolant. If engine will be exposed to freezing temperatures, make sure
closed cooling section is filled with an ethylene glycol antifreeze and water solution
properly mixed to protect engine to lowest temperature to which it will be exposed.
Quicksilver Premixed Marine Engine Coolant is already mixed.
