Hiya!!

For your motor, the few things I would do are these

1. Dump the correct amount of fuel stabilizer in your tank, then run your motor long enough for the stabilized fuel to reach the motor. If you have a canister fuel filter, you may want to empty that first, then reprime the system to save a bit of time and fuel.
2. Once stabilized fuel is running through your engine, shut it down and let it cool. I don't know how many people do this...I do it just to coat the cylinder walls...remove each plug and spray a little fogging oil in each cylinder, then turn the engine over by hand to help coat the rings, and piston chamber.
3. Button everything back up. Engine done.

If the boat is in a garage, I will always stuff a couple of dryer sheets into the exhaust housing of the engine just to deter any potential furry critter from trying to find a nice place to snuggle for the winter... I

Depending on time of use, Drain and refill the lower unit oil. If you are due for a regular oil change do it as well.

When spring comes, fire away and you will good to go...

Steve
