"These are well made, easy to use and sturdy muffs. My husband uses them to run his boat's outboards while flushing or testing the outboard motors. These are great because they are double sided and they grab and hold and seal very well to the motor while using. For the quality of the product, the price is a fantastic value." - Monica Better Boat® Customer

Top quality
"These work well, seem to be made of top quality materials. Time will tell but for now, very nice product."

Easy to use
"This is a quality set of boat motor muffs at a decent price. My old muffs had the garden hose screw-on attachment on one side only, so I like that this one has the fitting at the back, so each side gets the same amount of water.
This works great for supplying water to cool my inboard/outboard engine via the stern drive while I’m running it on the trailer. It would no doubt work great on an outboard engine as well."
— Dean. , Better Boat® customer

Heavy duty
"I have an old set of muffs for my boat that are probably 20 years old. I use them to test my Inboard/outboard motor each spring before we launch the boat for the season. I have noticed my old muffs only inject water on one side. thus why i got these as these inject on both sides. When I got these I was surprised how heavy duty they were. very study made and nice thick hoses. This is a Hugh improvement over my old set and will be using these for many years to come."
