• Helps remove salt, sand, and mineral deposits from cooling passages
• Prevents corrosion and extends engine life through regular maintenance
• Connects to standard garden hose for convenient operation
• Compatible with most inboard gasoline and diesel marine engines

Regular flushing with this device is particularly important for boats operated in salt water, as it removes corrosive salt buildup from the cooling system. This simple maintenance step can significantly extend the service life of your engine's cooling components including heat exchangers, thermostats, and raw water pumps.
