Draining Instructions

DRAINING SEAWATER (RAW-WATER) COOLED MODELS
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 com-
plete draining of cooling system.
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 corro-
sion damage to engine.
