Got tired cowl vents? What did you do to restore or replace yours? Below is what my PVC cowls looked like after just 16 months so rather than paint or replace them In-kind I went with these reasonable Buchan Marine 4" oval stainless cowl vents. They came with 6 screw hole deck plate that had the same OD and screw holes closely matched the original PVC deck plate screw holes. Took about an hour to replace with butyl bedding tape.
