Flush motor well if used in salt water.Fill your tanks with gas. Add gas stabilizer liberally (more is better than less). Do this whether you keep your tanks in or out of the boat. Definitely do it if you have permanently mounted tanks. Stabilized gas will be pretty much the same as fresh gas out of the pump when you start her up in the spring. Full tanks mean no water condensation (water in gas) plus less air to lose componets of gas to evaporation (less vanishing).
Fill oil tanks up (2 stroke VRO or DFI) - to get as much air out as possible. Change oil on 4 stroke.
Follow mfg recommendations on winterizing tempered with local knowledge.
Drain and refill lower unit with lube. I then will also drain this and refill again in the spring to make sure that if any condesation occurred it has been removed. If you don't refill (some don't) then tie a tag on the sterring wheel and trailer tongue - you don't want to be going out without lube in the lower unit.
clean and remove any waterline stains.
Open covered area in stern to observe blind bolt heads. Make sure no water is trapped.
Cover the boat.
Remove any electronics that you can. Temp cycling can be tough on solder joints. If your temp doesn't change to much, don't sweat it. (I live here in Minnesota - lots of serious swings in temp).
Remove batteries. Charge fully and then at least monthly from then on over the winter. Keep them above freezing if you can. Make sure you have a good trickle capable charger. Check water monthly.
