      Comments about Flexible PVC Cowl:

      I use this vent to ventilate the anchor rode locker on my 30 foot sailboat. The original identical vent lasted 37 years on a boat that averages a race or short cruise once a week.

              We lost our 30+ year old Nicro Marine snorkel and found the replacement to fit perfectly in place of the old. The replacement snapped right into the old mounting bracket and with the securement tab we will be sure not to loose the new one.

              UV eventually destroys plastic

              The plastic becomes soft, sticky and spongy after a year's exposure to sunlight. Then it absorbs dust and turns black. I've replaced the vent twice now. None of the surface treatments I've tried (one recommended by WM) have helped. Since it's flexible, painting the plastic isn't an option. I've seen severa other boats with the same grey to black discoloration on the top of the vent surface.

                Comments about Flexible PVC Cowl:

                Easy to install and matched up screw holes with the manufactures original.

                Product was good, but West Marine erroneously ship one correct vent and one dock bumper instead of two cowl vents.
