Hay bill just got back I was out sailing all last week .But no I did not do the vent instole my self.But no big deal.Allyou do is by a Nicro day& night 2000 vent from west marine 4" stainless 4 3/4" Model# 386193 N icro #n20504S $139.99 Take the vent to home depot and get a hole cutter the right size .Cut hole in deck ,seal deck core with epoxy filler,seal deck ring in place with 4200 sealer pre drill 4 holes and run the screws in snug,when sealer hardens run screws down tight. clean extra sealer off .slide vent in hole put in bug screen and screw in vent from bottom . no big deal I instoled one last weekend to replace my old soler only vent.
