I store mine up on the transom saver during late spring/summer/early fall, but I lower it to the full down position (skeg lightly resting on a block of wood) during the winter. I also put jack stands under the trailer frame during the winter. That way, if I climb up into the boat, the devastating effects of adding my weight to the boat won't damage the skeg. During the spring/summer/fall, I alway drain the propeller hub after I trailer the boat so very little/no water is left to evaporate.
