Well, I’ve been cleaning and getting ready for another great year of boating, I have been considering adding another bilge pump, I have one now, it’s a great pump and has never let me down. How many pumps does a 65’ Boat need, two/three? There were two engine driven pumps but they are inoperable, I had a 110v pump but I found out it was junk during my bilge cleaning fun. Well let the bullets fly
