Why you need this: Prevents buildup of salt, sand, and silt that cause corrosion, block cooling passages, and reduce motor life. Regular flushing with fresh water helps maintain performance and extends the service life of your outboard or stern drive. Effective flushing performance: Designed to direct fresh water into the engine’s cooling inlet to dislodge and remove salt, sand, and silt. Using a garden hose, you can flush deposits from cooling passages without running the engine in open water. Sturdy construction for reliable use: Built on a black coated spring steel frame that holds its shape and maintains a secure connection to the water inlet during flushing. The durable materials resist deformation and help ensure consistent performance over repeated uses. Easy connection and operation: Includes a hose connector that fits standard garden hoses for quick attachment. Simple to connect and start flushing in minutes — no special adapters required for most residential hoses. Broad compatibility: Designed to fit most outboard motors and stern drives that have side water inlets. Intended for use with engines featuring side-mounted cooling connections; confirm inlet orientation on your motor to ensure fit. Use scenarios Post-saltwater trips: Flush your motor after returning from saltwater to remove corrosive salt and prevent pitting and corrosion in cooling passages. Shallow-water or silt-prone areas: Rinse out sand and silt after operating in shallow or muddy water to reduce clogs and overheating risk. Seasonal maintenance and storage: Perform a thorough fresh-water rinse before winter storage or extended periods of inactivity to minimize deposits and corrosion. Practical notes Fits most side-inlet outboards and stern drives; confirm inlet location before use. Attaches to standard garden hoses for straightforward setup and operation. Robust spring steel frame provides secure, stable connections during flushing. This tool offers a simple, durable way to protect your motor by removing contaminants that cause wear and cooling problems, helping maintain performance and extend engine life.
