Cleaner engines.
Longer life.
The Quantum 25 clears salt, sand and mineral buildup from your engine's full cooling circuit in one push-button cycle. No hose-holding. No ear muffs. No guesswork.
Protect your engine.
Protect your investment.
Saltwater quietly wears down every cooling passage in your outboard. FlushStar checks all the boxes.
✓Hassle-free
One-touch startup runs the full cycle automatically, so you're not stuck at the dock for an hour babysitting a garden hose.
✓Eliminates awkward engine access
FlushStar connects to a standard flush port — no climbing over the transom to reach a factory plug or line up a set of ear muffs.
✓Takes the guesswork out
Trackable progress. Built-in diagnostics log total runtime and completed flush cycles, so you know the job got done right. Every time.
Two steps. Then walk away.
The boat can be in the water or on the trailer. The engine never has to run — which means no noise, no emissions and no fuel burned to protect your motors.
Connect freshwater
Hook a standard garden hose to the FlushStar inlet. The system is already plumbed to each engine's flush port, so there is nothing to align and nothing to guess at.
Press start
One button. A controlled pressure build and release flushing sequence runs through every motor in the bank — one through six.
Walk away
The cycle runs unattended and shuts itself down. Diagnostics log the runtime and the completed cycle count so you have a record, not a hope.
Built around your engine bank.
Single outboard or a bank of six, the Quantum 25 flushes them all from one manifold on one cycle. Pick your setup below to see how the system is laid out.

Flush your motors, not your time.
One-touch startup
Press once. The full cycle runs start to finish without you.
Built-in diagnostics
Tracks total runtime and completed flush cycles on board.
Controlled pressure cycle
A build and release sequence that works the salt out of every passage.
No engine operation
No running motor. No noise, no emissions, no fuel burned.
1 to 6 engines
One manifold, one cycle, however many motors you run.
In or out of the water
Works on the trailer, in the slip, on the lift.
12VDC Plug n Play
Runs off boat power. No extra programming to set up.
Made in America
Designed, machined and assembled in the U.S.A.

Six minutes does the work of twenty.
Six minutes of flushing with FlushStar is equivalent to twenty minutes of running your engine in fresh water — without running the engine at all. A controlled pressure build and release sequence moves salt out of passages that idling never reaches.
