Many people think that the warranty on their outboard motor covers the engine at all times.
Your motor is only covered by the manufacturer during actual use. This may seem odd, but engine makers know that temperature and humidity changes that occur when a motor is in storage can cause corrosion of the internal engine parts, leading to failure when in operation. For this reason, we recommend that you 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. The fuel conditioner stabilizes 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.
