Yep, Johnson Cartridge Pumps are the only way to fly. Put some sort of waterproof quick disconnect on the ends of your power source wires, have a spare wired up with the proper ends to match and a swap out is <2min. I'd swap out the bilge pump and perhaps add a float enabled auto bilge pump as well, all Johnson cartridges, that way, in a pinch you can swap out one for the other. In fact, I had it happen to me the last day I fished DL, livewell pump died. Open the hatch, spin out the livewell pump, spin in the bilge pump and back in business, just need to remember to turn on the bilge when I want livewell. Made it through the day, swapped them back and installed a new livewell pump, now also have a spare wired up to go where ever it might be needed.
