I have a 1978 18' Starcraft American fiberglass boat and I am looking for 2 bilge vents. They need to be at least 17 3/4" long and 3 3/4" wide to cover the screw holes left from the old ones. Can anyone help?
Probably available here through the Iboats Marine store or at your local marine supplier.
Different styles and sizes available...Hope this helps.
