Be sure that disconnected hoses will not become entangled in the
engine belt when the engine turns over. Failure to do so may result
in damage to the engine and/or critical boat systems.
Step 5
For boats equipped with an engine flush kit you must winterize the
engine flush fitting mounted to the transom of the boat:
• Remove the boat from the water.
• Drain the engine according to the Ilmor Engine Owner’s Manual
included with the Owner’s Manual Information Packet.
• Add one (1) gallon of marine grade antifreeze to a five (5)
gallon bucket.
• Attach a garden hose to the flush valve adapter mounted on the
transom. Place the other end of the hose in the bucket with the
antifreeze.
• Start the engine and allow the engine to draw the antifreeze into
the motor. DO NOT EXCEED 1100 engine RPM. Once all the anti-
freeze has been drawn out of the bucket and into the engine, turn
the engine off to prevent loss of antifreeze or overheating.
Step 6
Use duct tape to seal exhaust flaps to prevent dirt and nesting
rodents from entering the engine or exhaust system.
Step 7
On X26 boats equipped with a head, clean the tanks with a mild
cleaner or warm soapy water that will not harm the tank. Avoid all
petroleum-based household cleaners. Always clean and dry the
head before storage. Failure to do so may cause unnecessary odors
and damage to the tanks, which are not covered under warranty. If
using antifreeze in the head, drain the potable water tank and add
freshwater antifreeze to the potable water tank. Flush the antifreeze
and water mixture through the head and into the waste holding
tank. Then empty the holding tank. Never use automotive-type anti-
freeze in the freshwater system.
Step 8
Prepare the bow thruster (if applicable) for winterization by
removing the boat from the water and, with the battery switch on,
hold the bow thruster joystick to each side for approximately two
to three (2-3) seconds. This will pump water out of the thruster. A
small amount of water will remain in the thruster jet. Bow thrusters
should not be used if temperatures are near or below freezing as
a small amount of ice may have formed in the pump and could
potentially damage the pump if used before thawing.
Do not operate bow thrusters at or near freezing temperatures.
Failure to do so may result in ice damage to the thruster that may
not be covered under warranty.
