01 · Directly at the engine
Engine Quick Connects
Controller → Quick Connect → engine.
Connect the Controller’s outlet hose to a compatible Quick Connect at the engine’s factory flush port. A simple choice when those ports are easy to reach.
Automatic timing. Your choice of connection.
One Controller. Three ways to connect.
The Flushmaster Controller sends water to one engine at a time, handles the timing, then moves to the next engine and shuts off when the cycle is complete.
Connect it through Engine Quick Connects, a Reroute, or compatible Water Inlets. The connection gets water to the engine. The Controller manages the routine.
SEE THE SEQUENCE
How the Controller works.
One engine at a time.
Connect one fresh-water supply to the Controller and a separate outlet hose to each engine’s connection. Select the engines, set the required flush duration and press Start. The Controller opens one outlet, completes its timed flush, then advances and shuts off after the last engine. Try the sequence below.
Accelerated illustration. Set actual flush times and follow the procedure specified by your engine manufacturer.

The same Controller works with all three.
Choose the connection that fits your boat. Each engine needs its own separate route. These are three alternatives for that route—not three products you need to buy together.

02 · Connections within reach
Flush Port Reroute
Controller → Reroute plate → engine.
Permanent hoses bring each engine’s flush connection to an accessible plate inside the boat. Connect one Controller outlet hose to each plate port.
03 · Individual onboard inlets
Quick Connect Water Inlet
Controller → Water Inlet → engine.
A solid 316 stainless steel Quick Connect Water Inlet connects to compatible onboard flushing plumbing. Use a separate approved line to each engine and confirm mounting and fit.
HOW THE REROUTE WORKS
How the Reroute works.
Bring the connections to you.
The Reroute changes where you connect: permanent hoses run from each engine to its own quick connection on an accessible plate. It does not split one port between engines. Flush manually at the plate, or connect a Controller to automate each separate line. Switch modes below to see how they work together.

Garden Hose
Ready to Connect
Connect your garden hose at the plate using the included female adapter. Turn the water off before disconnecting and moving to the next outlet.
Ready to Connect
- Blue = water to one selected engine
- Dark hose = attached, no water flowing
- Dashed = concealed engine hose route
Demo is sped up. Set your actual flush time and follow engine position and engine-off requirements in your engine manufacturer’s instructions.

Why one engine at a time matters
Sequence the engines. Don’t split the water.
Multiple engines still need adequate water for the full flush duration. The Controller sends your available supply through one active outlet at a time, instead of sharing it across several engines at once.
One supply shared across open branches
SIMULTANEOUS FLOW
Splitting shares the supply
Opening several branches from one hose divides the available supply. Each engine may receive less water than it needs. More outlets do not create more water.
One active engine; the others wait their turn
FLUSHMASTER CONTROLLER
Sequential flushing dedicates the supply
One outlet opens while the others stay closed. Each selected engine gets its own timed turn before the Controller advances, so the active flush is not competing with the other engines for that supply.
Choose the Controller for your boat
Right capacity. Right hose reach.
Manual flushing remains an option with a compatible connection. Add a Controller when you want it to handle timing and move through your selected engines.
One Controller. The right capacity.
One or two engines: choose the 2-Outlet Controller. Three or four engines: choose the 4-Outlet Controller.
Retail Controller packages include outlet hoses. Choose the length after measuring the route to every connection; you do not need to add a replacement Hose Kit for a new standard package.
The Controller manages flow from your supply. It is not a pump and does not increase supply pressure.
Mount, protect or store
Complete the setup you will actually use.
Choose accessories for a specific job. A fixed dock may benefit from a Cradle and Suncover. A setup that travels may benefit from a Storage Bag or suitable removable mount. Check what comes with each product before buying more adapters or hoses.

For installation, use the product-specific instructions in Guides & Videos and follow your engine manufacturer’s flushing procedure.
Choose one improvement, then complete it.
Start with the product that solves your main issue. Confirm compatibility, choose the right quantity and hose reach, then add mounting, storage or protection only if it helps your setup.
