Personally, I would install a bilge pump connected directly to the battery with a switch and fuse at minimum. When I installed mine, I bought weather pack connectors for the fuse panel, an on-none-on switch, and a 3 wire water proof connector. I used Sea Doo's bilge pump installation instructions for most of my install, bilge location, wiring to fuse panel, and fuse location. With the way Sea Doo does it you only have the pump running when the guage cluster is activated, so on switched power. I wanted to be able to run mine any time I wanted to. That is where the switch, connector, and some additional wiring comes in. I had the depth finder installed when I bought mine so I had the second "Accessory" fuse panel to use for an always hot feed for the pump. I ran a wire from the battery to the fuse panel, fuse panel to 3 wire connector, 3 wire connector to one switched leg of the switch. The other switched leg is the switched power from Sea Doo's installation instructions. The common leg of the switch goes to the positive connection of the pump. Ground from the pump is wired just like Sea Doo's installation instructions. All wires are going to/from the fuse panel's except for the "Always Hot" feed at the battery. Looks OEM, and all connections are waterproof.
