Flush Port Quick Connect for Mercury Outboards

The Flush Port Quick Connect for Mercury outboards makes flushing your Mercury outboards easier, faster, and more securely. Designed to replace factory flush ports, this kit installs in minutes and gives you a permanent, leak-free connection built to withstand the toughest marine environments.

Crafted from durable, corrosion-resistant materials, including 316 stainless steel and high-grade polymers, the Flush Port Quick Connect is built for life around saltwater. With the included 90-degree elbow fitting, you’ll avoid hose kinks and ensure maximum water flow for a more complete, effective flush every time.

Whether you're flushing with your Flushmaster system or a standard water hose, this upgrade means no more stripped threads, no more frustration, and no more excuses — just a faster, easier way to protect your engine and extend its life.

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

Features:

  • Replaces OEM Flush Port
  • Marine-Grade & 316 SS Construction
  • Leak-Free Performance
  • Easy To Install
  • Hassle-Free and Saves Time

What's Included?

  • (1) Mercury Male Quick Connect
  • (1) Female Hose Quick Connect (Black)
  • (1) 90-degree Elbow (goes inside the cowling to ensure no kinks are in the Mercury flush hose; use if necessary)
  • (1) Wrench for Tightening
  • (1) Stainless Steel Hose Clamp

Product Installation:

  • Remove the OEM Mercury flush port plug.
  • Unscrew the Mercury OEM plug from the 3/4" female hose outlet.
  • Remove the lanyard from the engine hose.
  • Thread your new Flushmaster Flush Port Quick Connect to the flush port.
  • Reinstall the Flushmaster Flush Port Quick Connect into the engine cowling.

Helpful Tip: Remove the cowling and inspect the flush hose for any kinks. If a kink exists, replace the Mercury 3/4" female hose outlet with the provided elbow. Orient the elbow inside the cowling to ensure no kinks are in the Mercury flush hose. (To help insert the 90-degree elbow, lube the barb or use a heat gun on the flush hose.)

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Size: 300 Milliliter, Size: 300 Milliliter
Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.

This stuff really works fast and improves mpg like you won’t believe
Size: 300 Milliliter
I’ve tried many other types of fuel injector cleaners but this brand is amazing. I ran my truck down to less than a quarter of a tank of gas and poured it into the tank. I then drove 30 miles to an appointment and spent an hour in the appointment on the way home I noticed my mpg had gone up significantly. My truck tells me how many miles per gallon. I’m getting as I drive. I had gotten a code and I replaced the mass air filter and found a slight crack in an air hose, which I replaced that help with my code a little bit, but cleaning the fuel injectors with this product made such a significant difference. I just simply had a hard time believing it, but it’s true. I’m done with all those other brands of fuel injector cleaners which never really seemed to help much if you really want an amazing experience give this product to try.
