Storage Preparation
The major consideration in preparing your outboard for storage is
to protect it from rust, corrosion, and damage caused by freezing
of trapped water.
The following storage procedures should be followed to prepare
your outboard for out of season storage or prolonged storage (two
months or longer).
NOTICE
Without sufficient cooling water, the engine, the water pump, and
other components will overheat and suffer damage. Provide a
sufficient supply of water to the water inlets during operation.
FUEL SYSTEM
IMPORTANT: Gasoline containing alcohol (ethanol or methanol)
can cause a formation of acid during storage and can damage the
fuel system. If the gasoline being used contains alcohol, it is
advisable to drain as much of the remaining gasoline as possible
from the fuel tank, remote fuel line, and engine fuel system.
