Fill tank full with gasoline and a liquid gas stablizer.
Remove plugs and spray in Engine Fogging Oil (2-3 seconds each) and also spray the exterior of the engine. Run engine for 10 seconds.
Put a trickle charger on the battery.
If the storage area will get below freezing, tip the jetski to ensure any water flows out.
Put the trailer on two jack stands to lift the tires off the ground.
Done... and much cheaper than paying someone $150+
