Vallely Sport & Marine

Bismarck & Minot, ND

Service & Parts

Factory-certified technicians servicing boats, pontoons, PWC, ATVs, side-by-sides, motorcycles, and snowmobiles. We service what we sell — and most other major brands too.

What We Do

From routine oil changes to complete engine rebuilds — our certified technicians handle it all at both locations.

Factory Certified Technicians

Factory Certified Technicians

Factory-trained and certified across every brand we carry — Bennington, Lund, MasterCraft, Sea Ray, Yamaha, Polaris, and more. Our technicians hold manufacturer certifications and attend ongoing training to stay current with the latest diagnostics, repair techniques, and model updates. The expertise to diagnose, repair, and maintain your investment the right way.

Routine Maintenance

Routine Maintenance

Oil changes, fluid checks, belt and impeller replacement, battery service, and scheduled tune-ups to keep your machine running at peak performance. We follow manufacturer-recommended service intervals and use genuine OEM parts on every job. Preventive maintenance saves money and keeps you on the water or trail longer.

Parts & Accessory Install

Parts & Accessory Install

Electronics, trolling motors, fish finders, tops, covers, wheels, tires, and more. We stock genuine OEM parts and install everything we sell. Our parts department carries a deep inventory across all brands — and if we don't have it, we can get it fast through our manufacturer-direct supply chain.

Warranty & Insurance Repair

Authorized warranty service for all brands we carry, including Yamaha, Mercury, Polaris, and Brunswick. We handle insurance claims and warranty paperwork so you can focus on getting back on the water or trail. Our service writers work directly with manufacturers and insurance adjusters to expedite the process.

Storage & Winterization

Storage & Winterization

Heated indoor and outdoor storage at both Bismarck and Minot locations. Full winterization service includes shrink wrap, engine fogging, fuel stabilization, battery maintenance, and fluid protection. Book early — storage spots fill fast before freeze-up. We'll keep your investment safe through the harshest North Dakota winters.

Spring Prep

Spring Prep

De-winterization, fluid checks, battery service, hull inspection, and water-ready detailing. Get on the water first — book your spring prep appointment early because slots fill fast. We'll make sure your boat, pontoon, or PWC is ready for opening day. Includes full systems check and test run.
