Note: I added the comment about not needing to change the engine oil since this is a 2-stroke engine.

Stabilizer

Add stabilizer to the fuel. It is best to do this before your last outing so it mixes fully with the fuel in the tank, lines, and in the fuel injection system.

Fuel Line Part I

Disconnect the fuel line & pull fuel pump fuse.

Gas

Run until out of gas. Do this with the hose connected and water running. Never run a Mercury 2-stroke engine without first turning on the water!

Spark Plugs

Pull spark plugs & squirt 2-cycle oil in each cyl, put the plugs back in.

Lanyard

With lanyard DISCONNECTED, turn engine over for 1-2 sec.

Fuel Line Part II

Reconnect the fuel line & put fuse back in.

Battery

Pull battery and store inside.

Gear Lube

Change gear lube (both intake grate & stator).

Engine Oil

This is a 2-stroke engine. There is a separate oil reservoir and smaller fill reservoir near the engine. However, this oil is mixed with the gas, so it doesn’t need to be changed, just topped off regularly to make sure it has enough.

Cover

Put moth balls in each of the drink holders, cover & seal.
