DC wiring a Hobie outback to run a watersnake trolling motor


I finally registered my kayak to be able to use the little Watersnake trolling motor I modified to fit into my mirage drive slot. So to make it easier it is time to wire through the hull so that I don’t have wires hanging all over that can get tangled up in a net or a fish. Which happened on my test trolling trip more then once.

Needed materials for the build

For this modification I wanted to make sure that when I am not using the motor that the system has plugs that have a waterproof cap on them. Or if I am using the motor in the rain or heavy swells that it has a tight connection. The best ones I could find were the SAE style of plugs and cables. This entire setup cost me less then $40 to order on Amazon.

My one word of warning on this is that before ever putting holes in a kayak for any reason always make sure that where you cut or drill is where you want them at. Once you cut the holes you cant change your mind to move it around unless you are good at hole patching. For my kayak I wanted a plug in the front that will keep the motor wires away from my feet.

For the first hole I put it up front just below the front hatch. This looked to be a good spot so that the connector from the motor went forward a short distance and should not be in the way to land any fish unless it was a salmon then nothing could be really be out of the way.

One huge thing to keep in mind on using the SAE plugs is to verify that the cord colors match. Going between the two in hull connectors will swap them unless you use an adaptor to swap it back. Which is actually included when you purchase the set of two socket ports.

The second hole that I needed I put just forward of the seat and pointed up. This plug will be used to plug the cable to my pulse modulator and then to my battery. For a watersnake motor it only comes in two speeds and both of those are to fast for trolling. For me high is about 4mph and low is 2mph. But by using a pulse modulator you can turn the motor into a variable speed motor. My original one I built works well, but with the sealed Plano box it is bulky and in the way. So I found one in a metal box that also has an amp meter on one side so you can see the draw coming through. This makes it handy to calculate how long your trolling battery can last. My only worry with the metal box is that it has the vents in the side to keep it cool but that also can let water in. The location I have it setup for is under my leg while fishing but it is something to keep in mind.

Next to find a day where the wind and rain are not to crazy to go out this fall.
