Re: 16ft ss what size bilge pump
i'd go with the biggest pump that will still work with your existing hull outlet. Mayfair (johnson pump) makes a 1000gph that will hook up to a 3/4" fitting, which is probably what you have. i'm assuming that you'll be boating at Lk Whitney or other local lakes, rather than takin her to the Gulf? this will make a difference. for ocean boating, i wouldn't go with less than 1200gph (=20 gal per miinute) for my "large" pump and maybe 600-1000 for the secondary
