One routine. Different jobs.

Flushmaster. One system. Multiple ways to connect.

Simplifying boat ownership, one connection at a time. Understand what each Flushmaster product does, choose the connection that fits your boat, and add automatic timing if you want it.

Step 1 · Connection

First, choose your connection.

These are three different ways to connect for flushing. Choose the one that serves your installation—you do not need all three for the same engine route. The Flushmaster Controller works with any of the three.

Flush Port Quick Connects

A · Connect at the engine

Flush Port Quick Connects

Upgrade a compatible factory connection at the engine. Use a garden hose for manual flushing, or connect an optional Controller.

Choose your engine brand
Flush Port Reroutes

B · Move the connection inside

Flush Port Reroutes

Relocate engine flush connections to an accessible plate on the boat. Each engine keeps its own hose route and port; add a Controller only if you want automated timing.

C · Choose solid 316 stainless steel

Quick Connect Water Inlet

A premium direct replacement or quick-connect option made from solid 316 stainless steel. Confirm mounting and plumbing for your application. Works with the Flushmaster Controller.

Check Water Inlet fit

HOW THE REROUTE WORKS

When the connection moves inside the boat.

A Reroute brings each engine’s flush connection to an accessible plate. Explore the separate hose routes, then compare manual flushing with an optional Controller. Quick Connects and Water Inlets are alternative connection choices—not extra products required for a Reroute.

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.

  • 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.

SEE THE SEQUENCE

One water supply.
One engine at a time.

Add a Flushmaster Controller to automate timing. Choose an engine count, then play the sequence. Engine-side connections are shown here; the same timed sequence works with a Reroute or compatible Water Inlets.

How many engines?

Accelerated illustration. Set actual flush times and follow the procedure specified by your engine manufacturer.

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.

4-Outlet model shown. Choose capacity and included hose length for your boat.

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.

Step 3 · 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.

See how the Controller and connection options work on a boat. Choose the connection path that fits your setup; add a Controller when you want automatic timing.

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.
