The FLUSHMASTER is a marine-grade plug-and-play device used to simplify the process of flushing your outboard motors- saving time, water, and ensuring proper maintenance.

With just the push of a button, your motors will flush one at a time for your set amount of time, shutting off after completion and blocking the flow of water. There is no need to return to the device, boat, or disconnect your hoses until your next boating adventure!

The FLUSHMASTER device can be connected directly to a water spigot, attached on the end of a water hose, or hung on a piling. We recommend connecting directly to a spigot nearest to your boat. Select the optimal hose length to accommodate your application.
