I use to always take the spark plugs out of the engine and spray fogging oil into the holes and inside the cylinders for winter storage.

I also unhooked the gas line form the engine and ran it at the ramp until the engine stopped. I think that still leaves some gas inside the carburetor bowl.

I keep my boat ready to go fishing and inside an unheated attached garage. I could take all the fishing stuff out of the boat and put a cover on it and leave it in the driveway next to the garage but I'd the last 7 to 10 years I've been keeping it in the garage and parking my truck outside in the driveway.

I have a load of fishing gear that I keep in the boat. Many of my rods/reels are left in the boat along with tackle boxes and other fishing gear that I don't want sitting outside in the cold. I even leave the Humminbird on the boat now. I probably should disconnect that and bring it in the house but I don't.

I don't always fog the engine anymore either. And I don't run the motor until it runs out of gas anymore either. I did that for the first 20 years of the boat's life.

I do however use sea foam in the gas and put some stablil in the gas tank which I think helps keep the boat running better.

I probably should fog the motor and run the gas out until the engine stops.

Oh, And I charge up the Optima Batteries before I put the boat away. I would charge them every month to top them off but the Optimas retain their charge unlike the other batteries that I used in the past. Optimas are made differently and will hold their charge for almost a whole year. So it's not much of a problem leaving them in the garage for a few months. I 'll charge them back up to full capacity next spring before I use the boat again.
