Muskrat Guards . . .
Hurley Muskrat Guards are 316 stainless steel, adjustable, and install inside the exhaust ports.
Any boat that has a wet exhaust with a discharge opening of about three inches or larger is at risk. A Muskrat, Water Rat, Otter or other vermins can and will swim up the exhaust to chew through a coupling hose to the inside of the boat or make a den. That also includes boats with underwater exhausts as these rodents & vermins usually look for underwater entrances leading upwards to hollowed out chambers. This is how many boats sink, even while tied to the dock.
This Exhaust Guard is also known as an Exhaust Mixer for when backing down on fish to mix the exhaust with water to keep the fumes from entering the cockpit or to just minimize the diesel soot on the stern of your boat.
Did you know: Marine insurance policies exclude damage caused by “vermins” which includes muskrats & otters. Protect your investment!
