Keep your outboard or stern drive engine running at peak performance with the Attwood Universal Motor Flusher. Designed to make routine marine maintenance quick and hassle-free, this flusher allows you to run fresh water through your cooling system while the boat is out of the water. Featuring heavy-duty rubber cups that form a tight seal over side water intakes and a durable spring-steel frame that firmly holds them in place, it effectively clears out harmful salt, silt, sand, and mineral deposits. Whether you're flushing after a day on saltwater, tuning your motor on dry land, or preparing your vessel for seasonal winter storage, Attwood provides a reliable, tool-free solution to protect your investment against corrosion and costly overheating.
