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 operate your outboard (even momentarily) without water circulating through all the cooling water
intake holes in the gearcase 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.
The most effective method of storage preparation is to add the recommended amount of Mercury Precision Fuel
Stabilizer and Mercury Precision Quickleen products as described on the containers to the fuel tank before the last
operation of the boat. Adding fuel stabilizer will help prevent the formation of varnish and gum in the gasoline. The
Mercury Precision Quickleen product will help clean and lubricate the fuel injectors.
1. Portable Fuel Tank ‑ Pour the required amount of gasoline stabilizer and Quickleen (follow instructions on
containers) into fuel tank. Tip fuel tank back and forth to mix stabilizer and Quickleen with the fuel.
2. Permanently Installed Fuel Tank ‑ Pour the required amount of gasoline stabilizer and Quickleen (follow
instructions on containers) into a separate container and mix with approximately 1 liter (1 quart) of gasoline.
Pour this mixture into fuel tank.
3. Pull the drain hose off the right side fitting. Hold open end of the hose over a container.
4. Loosen drain screw and drain the fuel filter chamber.
