I have to sink the slalom course on Lake Latonka today, tomorrow or Tuesday. My boat gets put away next weekend. Ordered new skins for the coaming pads, and engine cover. If they arrive in time they will be installed by spring, and the boat will look new again. You can spray fogging oil into the cylinders. I also take the tension out of the belts, remove the impeller from the water pump and store it in a small jar of antifreeze(pink RV type). I reassemble the water pump without the impeller in it, and reinstall it in the spring if it does not need to be replaced. If you see the beginnings of a crack or tear in the impeller, get a new one. I also remove the battery, and put it on the charger once a month during the winter. @Ajskier, you have all the bases covered..
