What Customers
are Saying

I have a process when I wash down, and this device simplifies that process.
Chad Norris
The Flushmaster is an affordable solution that takes the hassle out of waiting to change over and end the flushing process.
Bobby Redmond | OneWater Fixed Operations
Convenient and easy-to-use device that saves me a lot of time at the end of the day. I have mine portable on the end of the hose, so I can bring it with me when we travel.
Daryl Cooperrider | Service Manager of Tom George Yachts
Using the Flushmaster has truly simplified the flushing process. Connect, start, and I am free to do anything besides waiting to switch over and turn off."
Kevin Carlan | CEO of Mastry Engine Center
My boat has to bow in. I use Flushmaster on the end of my hose and flush the engines as I pick up loose stuff and unload the boat. It's done, and I'm ready to wash down.
Bill Herlong | Owner of Herlong Yacht Service
I got your system installed this weekend and it worked great! It saves me an hour going back and forth to my boat switching hoses. Perfect solution!

What length
hoses do I need?

All Flushmasters come with 3-ft hoses as standard, with longer hoses available to meet each customer’s application.

3-ft hoses are the recommended length if you will be connecting to a hose and placing the device in the transom of your boat.

Longer hoses are meant for fixed mount applications, for example when the device is connected directly to a spigot nearest to your boat. Furthermore, depending on the beam of your boat, longer hoses may be necessary.

Look at the applications below to see what hose length best fits your setup:

CONNECTED
DIRECTLY TO WATER SPIGOT
MOUNTED TO
A PILING
PLACED IN
THE TRANSOM

Take a look at the recommended applications to determine how you want to use your Flushmaster.

We recommend connecting directly to a water spigot and leaving the water on 100% of the time. Once you have chosen your preferred application, measure the distance from the device to your motors.

Hose lengths available are 3 FT, 5FT, 7 FT, 9 FT, and 12 FT.

How does
it work?

The Flushmaster is a true “plug and play” device.


After installation, the customer will simply press ON, and then START to begin the flushing process. After pressing start, the device will send water out of the first outlet for your set amount of time (pre programmed for 15 minutes), and then switch to the second outlet, and so on.

When the device has completed flushing all outboards, a completion sound will be audible, and the device will shut off blocking the flow of water. There is no need to return to the device, disconnect hoses, or shut the water off until your next boating adventure!

Extend your
outboard motor’s
service life

Many boaters often forget, or altogether skip flushing their outboard motors simply because the process requires too much time and effort; especially with multiple engines.

This then results in poor motor maintenance and a shortened lifespan. With our outboard flushing device, it makes the process so much easier and convenient, that boat owners are more inclined to flush their outboard motors after every use.

“I don’t normally write reviews, but I had to for this product. It is hands down one of the best investments I’ve made for my boat. Thanks, Flushmaster!”
