Re: Electric Bilge Pumps
In Response To: Re: Pumps ()

Friend years ago had to idea to invent a pump using an off the shelf electric bilge pump and tool style lithium batteries to make an electric version of the basic bilge pump.

Electric bilge pumps in kayaks is a thing that has been done more than once. Lots of links via google out there. A friend had one for a while. It was great. Flick a switch, water comes gushing out. For a large kayak like a tandem they are particularly good idea.

But electricity and water, salt water especially, don't mix. Even the smallest amount of salty water will create galvanic corrosion that the presence of actual available electric power greatly accelerates. Broken wires, short circuits and failed switches quickly ensue.

Sealing out the water from the electronics is theoretically straightforward, but in practice it is really hard. If you want access to batteries, a mechanical switch, or wires running between a box and the pump, chances are you will get some small amounts of salt and humidity where current flows.

I'm not sure what happened to my friend's pump. All I know is he no longer uses it.
