"Gary, stablizer in the gas &#
"Gary, stablizer in the gas (and then run it for a few minutes to get it through the motor) is always a good practice - and doesn't hurt to run it with stablizer all year, all the time.
A shot of fogging oil in the cylinders would be wise as well - just to make sure no moisture goes to work on it during storage.
Other than that all should be good. At this time though I would take the time to do the "spring" tune-up. If your motor is due for an impeller change, gear oil (which is good to change anually) or new plugs, throw them in now. That way at your first chance to get the boat out in the spring, you aren't running around looking for parts......."
