500 vs 750 vs 1000 gph bilge and livewell pumps

[Jeff Porter]

I am the original owner of a 2002 basscat pantera classic and was wondering if I can replace those yellow Mayfair 500gph (I think)cartridges with the 1000 gph that basscat sells today? The replacement cartridges look identical but wanted to make sure.  The bilge area has 5 pumps and I thought I would replace them all while I am in there.

Some dash circuitry will not handle larger pumps. If you have single bilge, then yes you can go 1000 gallons. If you have dual bilges you can go to 750. Individual switches should handle 1000 GPH.

Looks like a only have one bilge because this is what I see.

1. 2 pumps connected directly to livewell (recirc?)

2. 2 pumps connected each to a gray tube that looks like it is going to and from the livewell and one connected to bilge float also

3. 1 pump connected to gray tube with on/off valve

4. the bilge float wire has a separate brown and black wire that is just loose which I assume would have been 2nd budge pump?

if it matter for the switches, I do now have the A10 dash panel

 

I attached pics

What I see from your pictures is “Two pumps on your livewell-one is recirculate and other is pumpout”

One pump closest to transom is the “pump in”.  The next pump from that one is the “bilge pump”. The next pump up from that one is the “aerator” pump.

So you have a single bilge pump and since your “float switch” wire is disconnected, it probably is bad. That wire goes directly to the A10 panel as an input.  It would not go to an additional bilge pump.

Hard to say what you’ve got in work as there’s lots of tape and zip ties we didn’t use.

[Jeff Porter]

Yeah, I did tape connections and zip tie some out of the way.   I think JEH in La answered my last question.  Thanks to both of you!
