Boat vent
by Jeffrey from Sparta, New Jersey on September 30, 2015
The vent arrived on time and was exactly what I ordered. Unfortunately, the screw holes did not line up, so I will have to return it, but that is not iboats fault. I would definitely order from them again!

These are very pretty and sturdy, MUCH better than plastic. A drop-in replacement for the side vents on my '82 Cobalt.
