Flush Your Motors, Not Your Time

BUILT FOR HONDA OUTBOARDS

Stop the two-handed wrestle of flushing your Honda. This permanent, secure quick-connect replaces the tedious factory fumble, preventing lost O-rings and protecting your engine's cooling seal. Just snap the line together—it's faster, easier, and built for the salt.

ONE-HANDED SIMPLICITY

Stop wrestling with your flush port. Our Quick Connect turns the cumbersome threading chore into a simple, one-handed snap so you can get the water flowing in seconds.

NO MORE O-RING DROPS

Stop the dreaded O-ring drop. Since our system stays connected as a permanent bridge, the factory gasket stays locked and seated right where it belongs—not at the bottom of the lake.

MARINE-GRADE INTERNALS

Equipped with a 316 Stainless Steel spring, our female adapter handles constant salt spray and UV exposure without seizing—ensuring a reliable snap-on connection every time.

FAQs

Does this design stay on my Honda while I'm running?

Yes. Since the Honda flush line must be secured back to the cowling deadhead for the engine to operate correctly, our Quick Connect acts as a permanent bridge. The adapters stay snapped together while you’re underway, keeping the line secure and the system sealed exactly like the factory intended.

Why should I use this instead of a Y-splitter?

Y-splitters divide your water volume, which can prevent a thorough flush at the top of the Honda engine block. Because our Quick Connect makes swapping the hose take only two seconds, you can easily flush each engine individually with 100% water pressure to ensure all salt is removed.

Will the internal spring rust in saltwater?

No. We specifically use 316 Stainless Steel for the internal spring on the Honda model. It is designed to be exposed to the elements and salt spray full-time without corroding or losing its tension.

Can I use this without the Flushmaster Controller?

Yes. It works as a standalone manual upgrade. You just click your garden hose in for an easy 15-minute flush. We recommend the Controller for the convenience of not having to get back on the boat to swap hoses.

Is there a risk of the engine pulling air through the connection?

Our design actually improves on the factory setup. By using a double O-ring on the male adapter and keeping the connection permanently bridged, we eliminate the risk of the factory O-ring falling out or getting pinched, which is the most common cause of air leaks in the flush system.
