Routine Maintenance
Preventive maintenance saves money and keeps you on the water or trail longer. Our factory-certified technicians follow manufacturer-recommended intervals using genuine OEM parts.
Keep Your Machine Running Right
At Vallely Sport & Marine, we handle routine maintenance for everything we sell — and most other major brands too. Whether it's a Bennington pontoon, a Lund fishing boat, a Yamaha WaveRunner, a Polaris RZR, or a motorcycle, our Bismarck and Minot service departments are equipped to keep it running at peak performance.
Every service follows the manufacturer's recommended maintenance schedule using genuine OEM parts. We document each visit so you have a complete service history — which protects your warranty and boosts resale value when it's time to trade up.
Engine Oil & Fluid Service
Oil changes, gear lube, power steering fluid, coolant flushes, and hydraulic fluid checks. We use manufacturer-recommended lubricants and OEM filters on every job — boats, pontoons, PWC, ATVs, UTVs, motorcycles, and snowmobiles.
Belts, Impellers & Drive Components
Water pump impeller replacement, drive belt inspection and replacement, prop shaft service, and CVT belt changes. These wear items are critical to reliability — we catch them before they leave you stranded on the water or trail.
Battery & Electrical Service
Battery load testing, terminal cleaning, charging system diagnostics, and replacement. We stock marine and powersports batteries for most makes and models. Proper battery maintenance extends the life of your electronics and starting system.
Scheduled Tune-Ups & Inspections
Manufacturer-recommended service intervals including spark plug replacement, valve adjustments, fuel system cleaning, throttle body service, and full multi-point inspections. Keep your warranty intact and your machine running at peak performance.
We cover marine (boats, pontoons, PWC) and powersports (ATVs, UTVs, motorcycles, snowmobiles) at both locations. Don't wait until something breaks — regular maintenance is the cheapest repair you'll ever pay for.
