Seaworks Boat Winterizer Gravity Motor Cleaning Kit with Antifreeze – Deluxe System with Antifreeze Tank, Flusher, Hoses & 1 Gallon -50°F Marine Antifreeze for Inboard & Outboard Boat Engines

Complete gravity-fed winterizing system includes antifreeze tank with on/off valve, T-connector, shutoff valve, braided hose with fittings, flusher, and 1 gallon of premium -50°F marine antifreeze

Antifreeze circulates through inboard and outboard engines to flush out impurities, prevent freeze damage, and protect pumps, lines, and cooling systems during winter storage

Simple gravity flow design provides uninterrupted antifreeze delivery to your boat engine, ensuring thorough winterization without complicated equipment

Ready-to-use marine antifreeze is non-toxic, safe for the environment, and specifically formulated for boats — protects engines to -50°F during the coldest conditions

Please check with your engine manufacturer to confirm if the system should be drained before filling with antifreeze and whether antifreeze should remain in the engine or be drained before spring startup
