Author Topic:   stern light post adapter

I plan to install a portable 30 gal "rubbermaid" baitwell in the portside stern corner of my 16' Katama (not much space anywhere else).

Is it possible to wire a 500 gph bilge pump to the 2-prong stern light base (using the base like a cig lighter), or is the light wiring too weak to support a pump? Also, where could I find such an adapter that fits the standard Perco/Attwood stern light base? I couldn't find anything in the West Marine or Defender catalogues....
The pump is mounted on my transom but is removable, so it would be very convenient if I could plug it in near the stern when needed.

no answer, so I thought I'd ask again:

has anyone considered using the stern light-post adapter to run a small pump? Can the Attwood/Perko light posts be modified so they are used like a cigarette lighter?

This would only be for occasional use, I don't want to run wire from the console back to the stern if I don't have to.

If memory serves me correctly, the wire on my 500 GPH bilge pump is about the same gauge as what's on the stern light. So, my guess is there wouldn't be any problems. I don't think those pumps consume very much current, especially when you compare it to a light bulb where most of the energy consumed is converted into heat.

On sev'ral Montauks we've owned over the years, we always ran a Bait-Saver brand live well off the stern light wire. Even spliced in another wire tail on the later couple rigs to run two appliances at the same time and never had a problem. Never ran a 500 gph pump back there, but reckon that's not much more amp draw than the live-well aerator motor, so give it a try. Just re-wire you a little Perko connector onto the end of your pump lead that matches the two-prong connector that Whaler supplied on the end of their light leads, and you should be in bid'ness. As an alternative, inside the junction box (should be near the aft port corner of the hull, prob'ly tan/brown in color) there's a small block on which you could wire you a new hot lead altogether. Good luck.

So my question is, where can I get a short Perko adapter to plug into the stern light post? I could not find anything in the West Marine or other catalogues I have.... thanks, RV

I have never seen such an adaptor. I would find an old light pole and cut it off to desired length. Buy a nice plug and get ceative with attaching it to the light pole.
As for the size of the wire I would check it for heat build up after runing the pump for a while.

Good Luck

thanks for the suggestions. I cannibalized an old light post (cut about 6" from the base), reconnecting the wires to the bilgepump mounted on the rear transom, and plugged it in. The new 40 gal "rubbermaid" livewell works great. Total cost: about $25
