MoellerDUAL Water Feed UNIV MTRFLSH

Works as advertised. Because the perforations in the lower unit on my boat run vertically I was afraid I may not be able to cover them all since the rubber cups on this one appear to run horizontally but I bought it anyway assuming that I would be able to rotate the cups so that they are oriented vertically and I was able to do so. The clamp is strong and the rubber cups are heavy duty. When you put this puppy in place and turn the water on, she don't budge at all. Stays in place perfectly. Great product!

Bought this item for a using with a new etec 130. My mechanic prefers to use fresh water through the intakes. So I researched a bit and found the dual feed works well. Found this unit on Amazon and thought it to be a fair price. Can't be easier as a Prime buyer to one click and it's done. Item came quick and in good shape. It works as advertised. I added a couple of plastic wire ties to keep the hose attachment supported behind the motor and I am very happy with the way it works.

Moeller makes fairly high quality products and this is no different. Excellent quality and the dual flush ensurs you're getting water into both sides of the lower unit. The muffs themselves are made from very thick heavy duty rubber and the connecting spring is very strong too. So much so that the muffs are pressed onto the sides of the lower unit so tight that they barely leak out any water. Excellent!

Works great for flushing out my boat motor. The only problem I see is the hose fitting end is not very good, it seem to want to come off the flusher. I had another one like it, and had to throw it away, for the same reason, I had hoped they would have improved it, not the case.

Just bought this for our 1983 mercruiser 120 on a Searay Seville boat. We're having overheat problems so we needed this to run some diagnostics. We have vertical "vents" and this works really well, it just slips over them and it's held in place by tension. Great price, fast prime shipping. *I was not given this item for free nor did I receive a discount for an un-biased review.

I have to test my engine from time to time and this is a proven tool that works well. Just make sure you have it on as tight as possible over the inlets and keep an eye out for the motor expelling water when you turn it on. Works like a charm!

The unit is well constructed and seems to be of good quality. The problem s that I experienced was the cups are NOT easy to rotate and are extremely tight to the point that it seems they could brake if I forced them. The second point is the spring tension that holds the cups on to the motor seems to be so tight that I need help to put it on to the motor.

Good quality muffs. Love the dual-feed. The muffs twist (quite stiffly I might add... but I consider that a good thing - more sturdy). Fit on my Volvo Penta SX lower unit and was very snug. Had to put them on from the rear though right above the prop since they wouldn't reach the water intake ports from the front.... So I just avoided putting the boat in gear once it was running;)
