After you've made the minor cosmetic repairs to your Sea Doo GTX Limited, you can begin the real work of preparing the vessel for winter storage. Winterization is generally aimed at protecting the vessel against the elements and the effects of the season. Because the Sea Doo is a vessel, its winterization parallels that of most boats.
Water Out, Anti-Freeze In
Part of winterization for any vessel is removing any water from the motor. In the case of the Sea Doo GTX, the water drains through a drain hose that's normally closed off. The hose must be free of anything that may clog it. Another place where water accumulates is the bilge. Clean the bilge with a bilge cleaner -- available at most boating supply houses -- and rinse it with fresh water. Drain the bilge by lifting the front end of the Sea Doo.
Fuel System and Cooling System
All storage preparation is aimed at avoiding corrosion. For the fuel system, this means mixing the last tankful of fuel of the season with 1 oz. fuel stabilizer for each gallon of gas in the tank. Protect the cooling system by closing off the motor drain hose with the hose pincher. Fit a short piece of hose to the engine water outlet and pour a mixture -- half anti-freeze and half water -- into the short hose until it comes out the drain hose.
Preparing the propulsion system -- the jet pump -- for storage requires that you drain and replace the lubricant in the jet pump reservoir. Bombardier Recreational Products recommends either their proprietary lubricant or 75W90 GL5 Type C gear oil for the replacement. Additionally, pull out the flywheel guard and lubricate the grease fitting on the shaft. While you have the grease gun handy, pump grease into the grease nipple of the through-hull fitting, until it comes back out of the seal.
Cover the Sea Doo with an opaque tarpaulin if you plan to store it outside on its trailer. The opaque tarp will prevent sun damage to the gel coat finish and keep dust and grime from accumulating on the vessel. Never leave the Sea Doo in direct sunlight and never make a mooring the Sea Doo's winter storage location.
