i do the following on my boat.

- add marine stabilizer to the fuel and run it through the whole system the last trip of the season
- flush engine
- fog engine through the carbs
- pull spark plugs and shoot fogging oil into cylinder (don't over do it, 2-3 squirts), bump the starter to distribute the oil, spread some fogging oil on plug threads and reinstall plugs
- lightly spray head with wd-40
- vacuum out all lines (live wells, bilge, pee hole, intake vents in lower unit, etc)
- vacuum out any standing water in the bilge (get all the water out!)
- change lower end oil
- grease fittings
- grease prop spindle
- remove items that will get damaged in freezing temps
- pull the batteries and store inside
- put dryer sheets inside hull and compartments to keep the vermin out
- cover it up, be sure to cover the prop so water doesn't collect and freeze

there might be extra things to do with a salt water boat (fuel filter?). i am sure others will chime in.
