Stabilize the fuel and run through the motor.
Change the Lower Unit lube EVERY fall when you put it up. If it does happen to get any water in the oil it could freeze and crack your lower unit. Better safe than sorry and Lower unit lube is cheap. While your doing that, pick up replacement washer/seals for the screws that fill and drain the lower unit. They are about a $.80 apiece, again good cheap preventative maintenance.
If you have a water pressure guage disconect the hose from the back of the gauge and drain of water, this could also freeze and wreck your gauge.
Replace the fuel filter and plugs now, that way your boat is ready to go in the spring when your ready to go.
If your storing outside, place moth balls in the boat and compartments to keep rodents out. They will chew up your wires and cause all kinds of electrical headaches.
If you can't keep your batteries charged, take them out or they could freeze or at least shorten the battery life span.
Grease all fittings to get out any water that may be in the bearings and other areas, again the freezing thing.
Check all nuts, bolts and screws to make sure they are tight. Check electrical connections for corrosion.
If you store outside, make sure its covered good and tight, bow tilted up and drain plug out.
Finally fog your motor cylinders and piston. Just shoot it through the spark plug holes for each cylinder and rotate the crank shaft manually and spray cyclinders again. This is to make sure you have covered all the metal areas.
Come spring just fill up your tank, add some fuel treatment like injector cleaner or the like and your good to go.
Good luck, its really a whole lot easier and quicker than it sounds once you've done it a time or two. Its also a whole lot cheaper than having the dealer do it.
