Cordless bilge pumps

[macojoe]

I have 4 pumps in my boat, in the rear I have 2 1500 gal pumps with their own floats built in, and one to each battery. One is a bit higher then the other,so if I get a leak one on the first battery will come on. When that battery dies and the water comes up a little higher the 2nd pump comes on till the 2nd battery dies. This should give me a good amount of time for someone or me to see something wrong before its at the bottom!
I have a 3rd 800 gal hooked to a float, and switch on the dash (this one came with the boat) This one is able to be turned on or off throughout the day if I am getting water from rain , waves, anchor rope, ect, ect ect.
The 4th pump is also on its own float, and dash, its a 500 gal in the front of the boat as some water sits up there. This is just to help get anything that might sit up there. (It also came with the boat)

With all pumps going at same time I could get 4300 gal per hour!! And going off shore I am still not sure its enough should something go really wrong??
