"I have a 22 seasport, the main bilge pump is a 2000 GPH pump, I just put in a 2nd 1500 GPH pump which is just hooked up to a push pull switch/no auto float. That one is just for emerg backup...the boat used to have a masturator pump which I never used..it stopped working..the plumbing was still there so I made use of it with the 2nd pump. Think of your pump capcity in terms of how much water you could take on board in the waters you operate in. Big water and big open cockpit means potential for a big greeny filling her up. The longer your boats sits low in the water while water is pumped increases the likelyhood the engines get submerged and your problem gets worse. I personally think that there should be some cosmetically ok larger scuppers made for smaller boats with large open cockpits so that water can be dumped almost immediatly. Scuppers that could be locked closed in good water or at the dock and opened in bad water."
