SERVICE MANUAL NUMBER 26
MAINTENANCE
Cold Weather or Extended Storage
Precautions
CAUTION
Sterndrive unit should be stored in full DOWN position. Universal Joint bellows may
develop a “set” if unit is stored in raised position and may fail when unit is returned
to service.
CAUTION
If Power Package will not be used for an extended period of time or will be exposed
to freezing temperatures, drain water from seawater section of cooling system. Wa-
ter MUST BE drained to prevent corrosion and freeze damage to engine.
CAUTION
If boat is to remain in water after draining, seawater inlet hose must be removed and
plugged. The plug will prevent a siphoning action that may occur, allowing seawater
to flow from the drain holes or removed hoses.
CAUTION
DO NOT operate engine without water flowing through seawater pickup pump, as
pump impeller may be damaged and subsequent overheating damage to engine or
sterndrive unit may result.
CAUTION
Seawater section of cooling system MUST BE COMPLETELY drained for winter
storage, or immediately after cold weather use, if the possibility of freezing temper-
atures exists. Failure to comply may result in trapped water causing freeze and/or
corrosion damage to engine.
IMPORTANT: Observe the following information to ensure complete draining of
cooling system:
•
•
Engine must be as level as possible.
A wire should be repeatedly inserted into all drain holes to ensure there are no
obstructions in passages. Remove petcock, if necessary, to insert wire complete-
ly into drain hole.
IMPORTANT: To prevent threads in manifolds, elbows and cylinder blocks from rust-
ing out during storage, reinstall plugs using Quicksilver Perfect Seal on threads.
Never leave drain plugs out during storage.
NOTE: If possible, place a container under drains and hoses to prevent water from draining
into boat.
CAUTION
If engine is equipped with Closed Cooling System, Closed Cooling section must be
kept filled with a solution of ethylene glycol antifreeze and water (mix antifreeze to
manufacturer’s recommended proportions to protect engine to lowest temperature
to which it will be exposed). DO NOT USE PROPYLENE GLYCOL antifreeze in closed
cooling section. Seawater section, however, must be drained completely.
