Storage & Winterization
Protect your investment from North Dakota winters. Full winterization services at both Bismarck and Minot locations.
Beat the Freeze
North Dakota winters are brutal — and skipping winterization can mean cracked blocks, corroded fuel systems, and dead batteries come spring. At Vallely Sport & Marine, we handle full winterization and storage for boats, pontoons, PWC, ATVs, UTVs, motorcycles, and snowmobiles.
Storage spots fill up fast every year. Book early to secure your space at our Bismarck facility.
Full Engine Winterization
Engine fogging, fuel stabilization, coolant protection, and anti-freeze treatment. We follow manufacturer-specific procedures for every engine type — outboard, inboard, sterndrive, PWC, ATV, UTV, motorcycle, and snowmobile.
Shrink Wrap & Cover Service
Professional shrink wrapping protects your boat or pontoon from snow, ice, wind, and UV damage through the long North Dakota winter. We also install and fit custom covers for powersport units.
Battery & Electrical Prep
Battery removal, terminal cleaning, and trickle charge setup. Cold kills batteries faster than anything — proper winter storage keeps your battery healthy and ready for spring. We store removed batteries in a climate-controlled area.
Secured Outdoor Storage
Secured winter storage is also available at our Bismarck Location. Book early — storage spots fill fast before freeze-up. We'll keep your investment safe through the harshest North Dakota winters.
