Product Information

Flushing your Mercury outboard shouldn’t feel like a wrestling match — but if you’ve ever struggled with that impossible factory flush port cap, you know it often does.

Even on brand-new engines, removing the OEM cap is frustrating. It's wedged in tight, and many owners end up damaging or stripping it while trying to pry it loose with tools. The Flush Port Quick Connect for Mercury Outboards eliminates all that hassle, permanently.

This easy-to-install upgrade replaces the factory cap system with a secure quick-connect fitting that’s simple to use. No more digging at stuck caps, threading and unthreading hoses, or fighting to wedge the cap back into place after flushing. Just snap on, flush, and snap off—it’s that easy.

Our design also improves on Mercury’s original cap with a larger, more visible weephole indicator. Like the OEM design, this small drainage port helps detect check valve issues — but ours is easier to monitor at a glance, giving you faster warning and greater peace of mind.

Built tough for saltwater environments and daily use, the Flush Port Quick Connect is the smarter, faster way to protect your Mercury outboard — whether you’re flushing at the dock, on a trailer, or in dry storage.

Use it with a standard reinforced hose, or pair it with a Flushmaster system for the ultimate convenience.

NOTE: The opening in the top of the Mercury Quick Connect cap serves as an indicator of check valve failure and is required by the OEM

FAQ

How strong are the suction mounts?

Our suction mounts are rated up to 50+lbs of pull strength. Plenty strong enough for most applications.

Will these work on non smooth surfaces like rough kayak plastic or nonskid boat paint?

Our suction mounts only work very well on smooth clean surfaces. If your desired mounting area is not smooth you can use our thin adhesive discs to stick to any rough surface and then you will be able to suction to that disc.

How long do the suction mounts last before they lose suction?

This time limit varies depending on a few factors. For indoor applications with moderate temperature and ideal smooth surfaces (glass, gelcoat, sheet metal, plastic), suction should last several weeks without any loss of suction.

Over longer periods of time the pvc suction cup may stretch out so we recommend re applying after every use or as often as you can to maintain 100% suction power.

For outdoor use in hotter temperatures suction power time limit may be less which is why we recommend re applying after every use or as often as you can. That being said, we have had several products in direct sunlight in the south Florida heat for a couple years and only re apply them every 30 days or so.

What size cup fits in your E-Sea Cup Holders?

You can fit slim cans all the way up to XL 32oz yeti tumblers. Unlike most 2 tier cupholders, ours actually holds your drinks upright so no angled tumblers.

Can I use these suction accessories on my inflatable paddle board?

Short answer, Yes! Our suction mounts will only work on smooth clean surfaces but adding an E-Sea Adhesive Disc to your board will allow you to mount all of our suction mounted products anywhere on your inflatable board.

Where are E-Sea Company products made?

We proudly make, assemble and package all of our products in the USA.

Will E-Sea Co. products deteriorate in the sun?

All of our plastic parts we manufacture are made with UV inhibitors which protect them from the suns harmful rays. No yellowing, no melting in the sun, no dry rot problems. As for the rest of our accessories; we only source the best quality with UV and Stainless Steel construction taking top priority.

Are these products saltwater safe?

Absolutely! We only use top quality stainless steel screws and material on our products. One of our best features is our suction mount construction not requiring any cheap metal parts; just heavy duty resin which will never rust.
