1. Seaworks Winterizer Diy Motor Cleaner & Flusher Kit

The Seaworks Boat Winterizer is a comprehensive system designed to flush, prepare, and protect your boat engine for winter storage. It is compatible with both inboard and outboard engines, making it versatile and suitable for a wide range of boats.

This kit includes an antifreeze tank with an on/off valve, a T-Connector, a shutoff valve, a braided hose with fittings, and a flusher.
