The factory cover is basically just a dust cover and won’t hold up to winter storage.
The enemy is snow and then water/ice pooling on the cover. The key is to have a heavy duty tarp with enough height and pitch to let snow slide all the way over the rail without pooling. The tarp needs to be supported the full length of the boat so no sagging can occur. Bow rips and those little mushroom things that sit in the seat sockets are absolutely worthless.
I have a solution the works really well and has done so for about 20 years. I built what I can only describe as a 17-foot long sawhorse. This “sawhorse” forms a ridge down the length of the entire boat from bow to stern and the peak of that ridge is a full 4.5 feet above the floor of the boat. The front legs of the sawhorse sit on the casting deck, rear legs sit in the well by the outboard. The “back” of the sawhorse is a 2×4 stood on edge for strength.
Then I just use a heavy duty tarp stretched over the sawhorse. There is enough pitch and the tarp is slippery so snow just slides right off and over the sides of the boat. Works perfect. I’ve sized my tarp so the whole boat is under the tarp and the tarp extends all the way down the sides of the boat so no paint is exposed.
The key is to get the pitch right so no pooling can occur. Guys always WAY underestimate how high the peak needs to be to get it right, on my little lund I needed to be over 4 feet above the floor to have enough pitch for snow and water to slide over the rail.
Heavy silver tarps last about 3 storage seasons. The whole solution is way cheaper than shrink wrap and reusable. Mice have never been an issue, in fact storing a boat in a garage is far worse for mice because the mice are trying to get into nice warm spaces, they don’t want to be out in the cold. I would put a couple of small containers of moth balls in and some dryer sheets and call it good.
In an ideal world, we’d all have 120 by 500 foot heated and air conditioned pole sheds so our boats adn all the other toys would never, ever be outside or get wet. Life is hard on boats here in the tunrda.
