*Tech Tip* If you are going to suck antifreeze from a bucket by using a piece of garden hose you must tape off the water inlet on the bottom of the boat in order to have an airtight suction.
HOW IT WORKS Flush Pro permanently installs in-line with the hose leading to your boat’s impeller pump. When you want to flush your boat, simply remove the Flush Pro cap, attach a garden hose, turn on the water and start the engine. Flush Pro automatically responds to the water pressure from the hose. The double valve system closes the hull intake and allows the hose water to circulate. When you’re finished, remove the hose and replace the cap. It’s that easy! And don’t worry, Flush Pro also closes automatically when the garden hose is removed to prevent water from entering your boat if you forget to replace the cap!
