88 Bass Hawk 196XL
My bilge pump has to be replaced and not sure if it is the original one or not. What is an average gpm size for a bilge pump? I have seen them from 450 gpm and up, so, what normal/average/a good gpm? I was in Cabela's yesterday and saw Attwoods 750, good bad or indifferent?
Thanks
Title says cfm...........I meant gpm.....thanks sconcon.

I believe you mean gpm. The bigger the better!
Yes...dang it, gpm.
Thanks
Go BIG- with built in float switch. Atwood makes a 1750 GPM, I think.
I went to the biggest I could without swapping hose size - 1000 gph.
Rule makes a 2000 GPM !!
If you ever get caught in a bad way.... You can't get enough GPM.
Done, I will heed your thoughts and go big.
thanks to all.
No one has ever said "I wish my bilge pumps were smaller".
I run 2 800gph pumps in both my boats. Depending on the length of hoses and height the water is getting lifted, bilge pumps May only pump 50% of their rated volume.
You can only push so much water through a 3/4 inch hose... No benefit running a 1000+ gph pump unless you swap to a larger hose and hull fitting.

My 1000 is still 3/4 rated.Originally Posted by 21XDC
Pumps are rated without any resistance...

They might have to refigure there head and hose length for most bass boats.
I have a 500gpm and I didn't put in the drain plug, got about 50 yards from doc and was looking at back of boat thinking why is it so low in the water. I turned on bilge and I knew right away I turned around got back to Dock climbed in water and got the plug in. Jumped in truck and back in trailer and got boat on. I didn't sink. But it worried me. Btw I usually keep plug in. But washed out bilge area and left it out to dry. Moral of story is I switched to bigger one got me worried.
I figure anyone who has boated very much has forgot the plug at least once.
Another thing that scared the chit from me... Years ago at Fork there were places where the timber had rotted off at the water line, but if the water level was up there were ACRES of stumps that were just under the surface. We were idling out of one of those areas one day....When I noticed there was water coming out of the floor vent and getting deeper by the second.. One of those stumps we idled over had yanked the plug.... We still had 100 yrds or so before we got to open water. by the time we did get to open water the boat was so heavy it would not plane out.. At least we could get going fast enough to drain the water.
I learned several things that day-- carry a spare plug... do NOT use the ones that cam over to tighten. If your boat does not have an Auto bilge switch GET ONE !!
Mine had a auto switch I disconnected it cause it got stuck. And was running all the time
ok, sooooooo, I am reading mixed on auto or switched. I guess there is good to both.
Thoughts on that?
I'd do the auto switch. Mine was just old got something in it made the float stick up. Just make sure when you get home to listen make sure it's not running.
Mine used to stick every now and then.. Every time it's because something was stuck under the float so it can't go back down. Simple fix was to place a screen around the float.
The benefits of having a working auto bilge are too many for me to be without one. The main reason is knowing within seconds of the bilge kicking on that for whatever reason you are taking on water..
More than once in the last 20 + years I have had the bilge kick on before I got the motor started to back off the trailer because SOMEONE forgot the plug.

Most bass boats today have two 750gph pumps, one with a float switch. I belive for the most part when you go above 750gph the hose size increases. Good luck.
Trash the float switches and get a contact switch, they will never jam on or off. Something like this:
