Do not run the engine without supplying it with cooling water. Either the engine water pump will be damaged or the engine will be damaged from overheating. Before starting the engine, be sure to supply water to the cooling water passages.
1. Wash the outboard motor body using fresh water. NOTICE: Do not spray water into the air intake. For further information.
When storing your Yamaha outboard motor for prolonged periods of time (2 months or longer), several important procedures must be performed to prevent excessive damage. It is advisable to have your outboard motor serviced by an authorized Yamaha dealer prior to storage. However, you, the owner, with a minimum of tools, can perform the following procedures.
TIP:
The use of “Yamaha Fuel Conditioner and Stabilizer” eliminates the need to drain the fuel system. Consult your Yamaha dealer of other qualified mechanic if the fuel system is to be drained instead.
For extra protection, remove the spark plugs and spray fogging oil in the holes to assure the cylinders and rings are also well lubricated. Rotate the flywheel a few turns to spread the oil inside and then put the plugs back in. here
A good fuel conditioner that's approved by the manufacturer may help to stabilize the fuel that you have in your engine's system to ensure that the fuel is free of water and other foreign bodies when you restart the engine in the spring. Also, fuel tends to break down during long periods of storage, transforming itself into a gummy substance that clogs your carburetor and fuel lines. Better to take care of it before the clogging happens than face stripping down your fuel system.
Take extra care to make sure that your engine is properly protected, especially when storing. You'll need fuel conditioner, grease, gearbox lubricant, and storage fogging oil. This is only general guidance. Always follow the manufacturer's instructions and recommendations and if these are inconsistent with anything here, defer to the manufacturer.
Fogging oil is used to prevent damaging corrosion from forming inside the engine during winter storage. The oil comes in an aerosol with a micro straw that can direct the spray into the carburetor throat and spark plug holes. Follow recommendations for your engine, including the product to use.
You should also drain and refill your gearbox with fresh oil and lubricate all the lube points on your engine such as shift and throttle linkages. Leave your oil system connected, first making sure that your oil tank is full. This will reduce or prevent condensation forming in the tank during storage.

6. Run the engine at a fast idle for a few minutes in neutral position while supplying fresh water. here
5. Cooling system flushing is essential to prevent the cooling system from clogging up with salt, sand or dirt. In addition, fogging/lubricating of the engine is mandatory to prevent excessive engine damage due to rust. Perform the flushing and fogging at the same time. here
2. Fill the fuel tank with fresh fuel and add one ounce of “Yamaha Fuel Conditioner and Stabilizer” to each gallon of fuel.
Boats that are hauled out are far less likely to be damaged during a storm than those left in the water. Using straps is effective at keeping boats from toppling over or floating away.
Only those built fairly recently are designed to withstand real hurricane force winds. Most built in the last few years are, but ask your facility.
If your marina can't haul your boat (boats are nearly always safer ashore), you'll need to move your boat to another one, which may be hard to do when a storm threatens.
