DRAINING CLOSED COOLING (COOLANT) MODELS
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 tow from the drain holes or
removed hoses.
IMPORTANT: Boat must be as level as possible to ensure com-
plete draining of cooling 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 temperatures exist. Failure to com-
ply may result in trapped water causing freeze and/or corrosion
damage to engine.
IMPORTANT: Closed cooling section must be kept filled year-
round with recommended coolant. If engine will be exposed to
freezing temperatures, make sure closed cooling section is
filled with an ethylene glycol antifreeze and water solution prop-
erly mixed to protect engine to lowest temperature to which it
will be exposed.
IMPORTANT: Do not use Propylene Glycol Antifreeze in the
closed cooling section of the engine.
1 Ensure engine is as level as possible to ensure complete draining
of cooling system.
2 Remove drain plug from heat exchanger.
3 Repeatedly clean out drain hole using a stiff piece of wire. Do this
until entire system is drained.
