Proper lay-up techniques can reduce start up hassles next spring. Any ethanol blended fuels can phase separate, introducing water into the fuel system. Injectors sitting static also have the potential to stick. Use a good fuel additive recommended by your engine manufacturer in the fuel system to help prevent fuel related issues.
Prior to winter lay-up, also be sure your battery is fully charged and that there is no draw on the battery. Some equipment may still drain the battery with switches off, so keep a battery charger running on the system or disconnect the battery if practical. Next, remove the vent plug at the top. Once the top plug is removed, the gear oil should freely flow out the bottom drain hole. As the oil drains out, observe its color and clarity. Gear oil in good condition should be translucent with a greenish cast, whereas a milky appearance indicates that water has made its way into gear box.
If this is the case, seek the advice of a service professional. New gear oil is always pumped upward from the bottom hole until it overflows at the top.
The reason it is filled from the bottom up is to eliminate the possibility of trapped air and ensure that the entire gear box casing fills with oil. There are two ways to pump in the oil. For very small outboards, one way is to press the nozzle of a tube of gear oil into the bottom hole and to slowly squeeze the gear oil into the casing until it overflows out the top hole.
For larger outboards, the other way is to use a gear oil pump. In either case, when the oil overflows out the top hole, replace the top plug, then remove the pump nozzle from the drain hole and quickly replace the plug. Gasoline fuel stabilizers help to prevent the formation of gum and varnish buildup and protect metal surfaces from corrosion during winter layup.
Next, you need to circulate the stabilized fuel through the entire fuel system. To do this, reattach the flushing muffs, turn on the water, restart the motor and allow it to run for five to ten minutes and then shut it off. To prevent freeze damage, prior to winter storage, many owners simply drain the cooling water out of their outboards. This will prevent residual water from turning into ice and causing damage during a hard freeze.
Dosing your motors cylinders with fogging oil prior to winter storage will prevent the formation of rust within the cylinders—which obviously is a good thing!

Hook up a garden hose to a motor flush attachment, which will cover the water intake on the lower unit of the motor. Turn on the water and then start the motor. Move the motor back and forth to help get all the water out. If you leave moisture in the motor and it freezes, you could crack it, which would cost you quite a bit to repair or possibly replace the motor next season.
Some experts recommend that you use antifreeze instead of water. The antifreeze will not freeze up inside the motor over the winter. Disconnect the fuel line from the outboard motor and keep spraying the fogging oil into the air intakes.
