Let customers speak for us
Great product! Easy to install and piece of cake compared to the standard way of flushing out my engine. No more lost washers either!
Amazing product and easy to use flush system
Perfect product for my 2026 Yamaha F200’s. Very responsive when I had questions. Proud to buy and use this companies products due to their quality and commitment to clients. Keep up the great work, Flushmaster
GREAT PRODUCT WORKS WELL ONCE INSTALLED...WAS A BIT MORE DIFFICULT TO GET 1/2" HOSE THRU THE TUBE AS WE DID NOT HAVE YAMAHA TUBES ON MY DUAL 300 HP ENGINES..WE USED TUBING FROM HOME DEPOT AND WD 40 TO SLIDE IT IN. WOULD BE HELPFUL IF YAMAHA TUBES CAME WITH THE PRODUCT. TO BE HONEST..COULDNT BE HAPPIER WITH IT'S PERFORMANCE.
Works great, should have added this years ago.
amazing product
Amazing. Should have done this sooner. Saves so much time
Great product, the double o-rings are an excellent touch. I bought 2 thinking one for my Yamaha 150hp and one for my 9.9 Yamaha. Does not work on the 9.9 kicker as it hits the linkage. Thinking a Tee might work.
Because I have 2 engines and I use both this product doesn’t really make sense right now. Hopefully they will work on a system for the kicker engine.
Great Product!
A must have for ease of proper flushing...
Arrived quickly
Outstanding product makes the engine flush extremely easy and convenient. There is absolutely no excuse to not get one!
Makes flushing soooooo easy. Plug in hose while I’m putting the cover on the boat and by the time I’m done with the cover I disconnect and hop off the boat. Hassle free
Wow, what can I say, it was a great experience, service dept. went above and beyond! I'm telling all my boating friends about how you back up your product! I am also a yacht broker, and I'm spreading the word to my clients!
Much Appreciation,

BEFORE YOU BUY
A little more clarity.
Do I need every Flushmaster product?
No. The Controller adds automatic timing and sequential flushing. Quick Connects at the engine, a Reroute plate, and a Water Inlet are alternative connection options. Choose the path that fits your boat; you do not need all three for the same engine route.
Does the controller flush all engines at once?
No. It sends water through one selected outlet at a time, moves to the next programmed outlet, and shuts off water when the cycle finishes. Use the procedure and flush duration specified for your engine.
Does a controller need boat wiring or permanent mounting?
No boat wiring is needed. The controller is battery-powered and can be used as a portable setup or with suitable mounting accessories. Choose its location first, then measure the hose route to each engine or rerouted flush connection.
My boat already has rerouted flush ports. What do I need?
Start with the connections already on your boat. A Quick Connect Water Inlet can replace compatible individual water fittings; a Flush Port Reroute can replace a compatible panel or connection layout. Confirm mounting dimensions, hose size, rear clearance, and one separate flush line per engine with a qualified marine technician.
Can I install a Reroute myself?
Installation varies by engine and vessel. Review the Reroute Installation Guide before buying or cutting anything, and have a qualified marine technician confirm the connection method. Stop and seek professional help whenever a step or engine connection is unclear.
