I'll never have another bass boat without a pump out. Once you have one you'll wonder how you did without it!

My current boat has a 750GPH fill and a 1000 GPH recirc if I am not mistaken. I can turn them both on at the same time and fill it up in min's. I get ready to drain it to cull (SELDOM ) or get my one fish out at weigh in (OFTEN ) it's over quick. While fishing in hot weather you can really move some water with the big recirc pump. You can only overflow water so fast on incoming water, that would be what limits your fill pump.

As to bildge pumps, my last Champion had two pumps. One 750 GPH manual, one 1000 GPH auto. I had to custom order it that way. I never needed both pumps.

My current boat has one pump that has an auto switch. I can use it on auto or manual. If I had ordered the boat I'd have the two pump system again. Either way if you really get in trouble you cannot pump water out fast enough to stay up. All it takes is a couple over the bow and you're full, two pumps just may get you back in case one fails.

My 2 cents worth.
