OFF-SEASON STORAGE You must protect against natural environmental conditions that can be damaging to an outboard motor. Temperature and humidity changes while your outboard motor is not in use can cause corrosion of internal engine parts when they are not protected. Fuel remaining in your fuel tank and in the engine will oxidize and weather which can result in loss of octane and can cause gum deposits in the fuel system. Your warranty does not cover engine failure caused by these conditions. We strongly recommend that you have your DEALER prepare your outboard for the off-season. To do the off-season storage preparations yourself, gather the supplies and perform the steps that follow: 2+4 fuel conditioner Triple-Guard grease Ultra-HPF gearcase lubricant Storage Fogging Oil spray can Stabilize the engine’s fuel supply with 2+4 fuel conditioner during the last hours of operation to ensure proper stabilization, following instructions on the container for mixture. Be sure to run the engine long enough for the treated fuel to reach the engine.
WARNING Prevent injury from moving engine components. Before starting the engine: Shift it to NEUTRAL.
Storage Fogging Oil — Following instructions on the can, fog the engine by spraying through the holes in the throttle plates in the throttle bodies.
Ignition, oil, and fuel systems — Check for misplaced leads and damaged or deteriorated parts. Be sure starter solenoid terminal boot and all connectors are in place. Screws, bolts, nuts — Tighten loose.

Propeller — Remove and examine. If damaged, see your DEALER. Clean the propeller shaft and lubricate it. Refer to Propeller. Gearcase speedometer pickup, if equipped — Disconnect the speedometer hose at the upper connection. With air pressure no more than 25 psi (167 kPa), blow all water from the gearcase speedometer pickup system. Reconnect speedometer pickup after all the water has been removed.
Keep hands, clothes, hair clear of powerhead. Remove the propeller if you use a flushing device. IMPORTANT: Provide a water supply to the engine and start it — run it at idle only. To run the engine on a flusher, refer to Flushing. To avoid difficulty when restarting, never run the engine with the fuel hose disconnected or run the engine out of fuel.
