Powerhead Long Term Storage

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).

CAUTION

Never start or run your outboard (even momentarily) without water

circulating through all the cooling water intake holes in the gear case to

prevent damage to the water pump (running dry) or overheating of the

engine.

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.

Fill the fuel system (tank, hoses, fuel pumps, and fuel injection systems) with

treated (stabilized) fuel to help prevent formation of varnish and gum. Proceed

with following instructions.

1) Portable Fuel Tank – Pour the required amount of Quicksilver Gasoline

Stabilizer (follow instructions on container) into fuel tank. Tip fuel tank

back and forth to mix stabilizer with the fuel.

2) Permanently Installed Fuel Tank – Pour the required amount of

Quicksilver Gasoline Stabilizer (follow instructions on container) into a

separate container and mix with approximately one quart (one liter) of

gasoline. Pour this mixture into fuel tank.

3) Place the outboard in water or connect flushing attachment for circulating

cooling water. Run the engine at 2000 rpm for 25 minutes to allow treated

fuel to fill the fuel system.

PROTECTING INTERNAL ENGINE COMPONENTS

NOTE: Make sure the fuel system has been prepared for storage.

1) Remove the spark plugs and add approximately one ounce (30ml) of

engine oil into each spark plug hole. Rotate the flywheel manually several

times to distribute the oil in the cylinders. Reinstall spark plugs.

2) Remove the water separating fuel filter and empty contents into a suitable

container. Refer to Maintenance Section for removal and installation of

filter. Replace fuel filter annually, or every 100 Hours of operation, or if

large amount of fuel contamination is present.
