Great product! Easy to install and piece of cake compared to the standard way of flushing out my engine. No more lost washers either!
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
The boat is on a lift. While pulling the flushing cap off, it came detached and fell into the water and sank, never to see again. There needs to be a floating cap or a stronger attachment device.
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.
It doesn’t work on my Yamaha 115’s
2026 Year Model. I’ll need to return the set.
Please advise on that process.
The O rings on these are trash. Leaking on all fronts. Not happy.
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.
A must have for ease of proper flushing...
Product worked as expected, however QC needs to inspect better. Ordered 2 separate systems for 2 different motors. One did not have the required O-ring so it leaked. Had to purchase an O-ring to make it work.
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,

It leaked a little and forced the hose into a pinch on my yamaha 150
Great product. Easy to install. You may need to trim your water line to prevent kinking but it’s a five minute job with clips and a new wire tie.
Really great item. It sure makes flushing easier.
