Comments about Perko Chromed Zinc Cowl Vent:
Note on my one con: base has 4 screws vs 3. I purchased a Perko product because my boat's original vent covers were Perko. Would have been nice if the mounting was uniform to prevent drilling of additional holes.
Service and delivery comments:
West Marine's service was good, timely and as advertised.
