Boat Winterization in Missouri:Boat Winterization Services

The inevitable Missouri winter poses the single greatest threat to your inboard towboat. Water trapped in the engine block, exhaust manifolds, or ballast lines will freeze, expand, and crack, resulting in thousands of dollars in repairs and months of lost time. Protecting your MasterCraft, Supra, Moomba or other Towboat Brands is not optional; it’s essential.

At Performance Marine Watersports in Osage Beach, MO, we provide a meticulous, factory-certified boat winterization service that guarantees total freeze protection for your high-performance vessel. Don’t gamble your engine’s safety; trust the experts who know these systems inside and out.

The Certified Winterization Checklist: Inboard Expertise

Inboard Boat Winterization Missouri, Certified Freeze Protection

Inboard towboats, with their complex V-drives and integrated ballast systems, require specialized care far beyond a simple flush. Our factory-certified technicians follow a multi-point process to ensure no water is left behind.

Engine & Cooling System Protection:

Anti-Freeze Flush: Draining all raw water from the engine block, manifolds, and cooling system, then circulating marine-grade, non-toxic anti-freeze (propylene glycol) to prevent freezing in critical areas.
Fuel System Preservation: Treating your fuel tank with a professional-grade stabilizer and running the engine briefly to circulate the stabilizer through the entire system, preventing gum deposits and corrosion.
Oil Change: Performing an annual oil change before storage to remove corrosive contaminants that accumulate during the season.
Engine Fogging: Applying fogging oil to the engine cylinders to protect internal components from rust and corrosion over the long winter months.

System & Component Protection:

Ballast System: Thoroughly draining and flushing all ballast tanks, pumps, and hoses, which are highly susceptible to freeze damage.
Freshwater & Head Systems: Draining all onboard plumbing, sinks, water tanks, and head systems, and treating them with plumbing-safe anti-freeze.
Battery Maintenance: Disconnecting, testing, and charging batteries for storage, often recommending removal for indoor storage or continuous trickle charging.
