The FLUSHMASTER is a marine-grade, portable 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.

Flush masterwith slight modifications

Works absolutely as promised… so easy even I can do it…. Works great and very efficient . Before I’d sometimes skip a flush to hit the pool. Now it a plug and go. Love it

Joe Kilman

Incredible product works better than I ever imagined! I have 4 outboards and this is so easy and quick. I had been looking for a quick and reliable flushing solution since I got this multi engined boat… I highly recommend this and getting the quick connectors.

Holy Sh**…. Amazing

Flush Master is a must have. Super easy! Clean your boat and flush your engines at the same time. It’s the easy button!

I bought the system to make it easy for my sons to flush the engines. They conveniently forget the boat needs to be cleaned after use. Problem solved.

Best flushing system ever!

Great product

Love the product, quick setup and engines are flushed while I’m washing down the boat without input from me. However, I wish it came with quick connectors at the control box end so I could remove hoses and store them in my dock box. This way they would be out of the way and protected from the elements.


Love m6 new unit and quick connects. Twin Yamaha 150’s. My wife hooks it upm after i clean the boat. Major time saver, works perfect and easy to use. Only thing I’d change is buying it years ago for all my boat motors in years past.
