My 420AC has a drain box for the kitchen sink and shower but what a gross maintenance item to clean out. The kitchen sink is high enough to drain overboard so thought is to put a thru hull drain in my cored hull. What is the procedure to do this? Thinking right diameter hole on outside and then larger hole to remove coring from the inside. Re-glass the inside and re-drill the hole. Or is it possible to use a dental pic to pull out the coring and pack the opening with chopped glass and resin?
