Spring Prep
Get on the water first. Book your spring prep early — slots fill fast, and we'll make sure your boat, pontoon, PWC, or powersport machine is ready for opening day.
Ready for Opening Day
After months of North Dakota winter, your boat, pontoon, or powersport machine needs more than a key turn to be season-ready. At Vallely Sport & Marine, our spring prep service is a comprehensive de-winterization, inspection, and detailing package that covers everything — so your first day out is a good one.
We handle marine and powersport spring prep at both our Bismarck and Minot locations. Early bookings get priority scheduling — don't wait until the ice is off the lakes.
De-Winterization & Fluid Service
We reverse every winterization step — flush fogging oil, replace engine oil and gear lube, check coolant levels, and verify all fluid systems are ready for operation. Every unit gets a fresh start for the season.
Battery & Electrical Check
Full battery load test, terminal cleaning, and charging system verification. We check all lights, gauges, bilge pumps, and electronics to make sure everything powers up and operates correctly before your first outing.
Hull, Body & Safety Inspection
Visual hull inspection for cracks, gelcoat damage, and hardware integrity. We check steering, throttle cables, safety lanyards, fire extinguishers, and navigation lights. For powersport units, we inspect tires, brakes, suspension, and frame.
Water-Ready Detailing & Test Run
Full wash, interior cleaning, and detail to remove winter grime. Marine units get a test run to verify engine performance, water flow, and shift operation. Powersport units get a road or dyno test. You pick it up ready to ride.
