  • Works perfectly
Color: Suzuki Black
Easy to install. Just take out the old plug and screw in the new one. Quick couple makes rinsing out engine easy and fast. Downside is this seems way overpriced for two little pieces of plastic! But looks like they have a monopoly on the market.

  • It WORKS! but.....
Color: Mercury Black
dudes.... it's way too expensive for what it is all about. I know that someone had to design it, make prototypes, go to China to ask them to build it, ship it back to CONUS, and then pay for shipping, and then bust us $70+ for it, but you would get that extra 40% in sales of people who were holding back like myself because we balked at the price. and.... it works great for me. LOL. ... show more

  • Short term failure
Color: Yamaha & Honda Black
I bought two for twin Yamahas. They installed great and worked great when new. In only three months, the spring mechanism in both units failed to work smoothly. This meant that after flushing, the reconnect wasn’t reliable, leading to the hose end disconnecting while the boat is in operation. They do not have any dirt or debris plugged in the connection. The spring mechanism simply is failing to push the collar back and secure the hose. I do not recommend these. I am now looking for a higher quality unit. ... show more

  • Game changer !
Color: Yamaha & Honda Black
On behalf of my husband, an avid boating enthusiast, I must say this Outboard Quick Connect Flush Kit has completely exceeded expectations. From the moment he started using it, he raved about its seamless design and user-friendly setup. Flushing the engine has gone from being a chore to an effortless routine. He’s particularly impressed by how securely it connects and the peace of mind it provides in maintaining the engine’s performance. We were also incredibly pleased with the vendor’s exceptional service. The product arrived promptly, carefully packaged, and exactly as described. It’s clear they take pride in offering top-tier products for boating enthusiasts ... show more

  • Cover on water inlet
Color: Mercury Black
this was quite a bit more expensive, but it's well-made and it has a cover on the inlet so I like it

  • Bad purchase!
Color: Yamaha & Honda Black
Purchased this in March 2024. Spring broke today so I could not disconnect it to flush. No one to call, no warranty information. Great concept. Waste of money to buy it from these guys since I see others now have the same issue. Changed my rating to 3 stars. Once I found how to reach out to the company directly they responded immediately and send me a new one at no charge. Based on some other reviews, I am not sure how long it will last but their customer service is top notch ... show more

  • Works fantastic, just way overpriced
Color: Mercury Black
Mercury's fresh water flushing connector has to the worst design of any outboard motor manufacturer. An absolute PIA. This flush fitting solves the problem perfectly, but for a simple plastic fitting it should be priced about half the price. I hope it is UV resistant. If not for the price, I would give it 5 stars. ... show more
