If you use to store the boat during summer outdoors, definately she won't get any more wear during winter. Take care of the engine though, cause if you leave it raised (trim all the way up), if might remain rain water in the exhaust, which may freeze during the night and crack the crankcase.
Besides the pistons of the trim remain exposed and might get rusty.
Having the trim all the down toy can avoid those 2 above mentioned.
