Let customers speak for us
Very happy with the system and look forward to using it more in the spring. I have to shout out to the customer service team. I initially purchased quick connects for my Yamahas. I didn't notice that it does not fit 450 engines. The gentleman I spoke to said the Suzuki connects will work with an additional rubber washer. He sent free of charge and told me to keep the other connect, which I'll probably give to a neighbor. Really appreciated the service.
The perfect accessory for the Flushmaster and can be easily modified to accept the sunshade.
Recently installed the Flushmaster, very pleased ! Installation is very easy and can be hooked to a hose or hard plumbed. Set your desired flush times and operation is literally pushing two buttons.
Customer service has been great, always responsive and helpful. Overall 100% satisfied !
Couldn't be happier with this company and product. I ordered the Flushmaster for my Mercs and love the ability to return to the dock, hook up my motors to the Flushmaster and walk inside without having to stand on the dock waiting for each motor to flush and then hook up the next engine. You don't even have to worry about getting back to the dock to turn the water off, the system holds the pressure from the hose until you are using it next time. The device is easy to use and gives you the ability to program the amount of time you wish to flush your engines.
I have called them with two different issues and without hesitation, they have puts the parts in the mail that day, standing behind their product. Such a relief of not having to debate who created the problem or what caused the problem. They are very customer orientated and will help you out if you experience any issues or just have questions.
Easy to install, easy to use! Just re-powered my boat and put this in for my quad Yamaha 300's. Makes it very easy to flush my engines and the customer service was outstanding when I called them to make sure I had everything I needed!
great investment hook it up with quick connections and walk away best purchase for the boat
Love the product!! No more forgetting the water is on while flushing!!
This is the best thing since sliced bread. So easy to use. This is the 2nd flushmaster I had to get. The first was replaced under warranty. Great service from a great company. Thank you Flushmaster
Saves a tremendous amount of time
I bought this product for my 2021 Mercury 250XL motor. The old, 'crappy', plug had gotten so bad I had to use pliers to get it open or close it.
This quick install has saved a huge amount of time when I pull back into my dock. I have one hose dedicated to the motor with the quick connect, and the other hose I start rinsing the boat down. 15 minutes later....all done.
Well done, Flushmaster!
Makes the worse part of clean up very easy.
