How best to route wires when mounting Xducer to electric motor?

5 posts in this topic

I moved my "skimmer" transducer from the stern of the boat (traditional mounting) to the bow mounted electric motor with the skimmer mount kit. I ended up using wire ties to fasten the cable loosely along the shaft of the electric motor (which is a Minn-Kota Auto-Pilot). I figured it would happen, but I ended up pinching the cable and semi-wrecking the cable (audible sparking). I was able to tape it up and I now get a ton of interference when the electric motor is on. I think there is a compromise in the shielding, and I'll look into it. I'll probably end up replacing the transducer.

My question is...how have people been successful in wiring their transducers on an electric motor? The challenge is the extend and retract needs of the motor and how to deal with that in the wiring (slack needed).

(My favorite option is replacing the electric motor with the integrated transducer, but that's not happenin'.)

Starting from the lower unit where your transducer is ..... cable tie the transducer wire to the bottom of the shaft, right above the lower unit.

Run the transducer wire through the handle you use to stow and deploy the motor.

Cable tie the transducer wire at the top of the shaft, leaving just a few inches of slack - enough for the motor to rotate around 1 time and maybe a tad more. You can leave this cable tie a little on the loose side until you get the right amount of slack figured out, then snug it up tight.

From there you just need to run the transducer wire to your unit.

Hope this makes sense and helps, good luck.

That makes perfect sense...thanks! I will give it a go.

Also the interferance may not be from your doing. My bow mount had issues. They have cables you can buy that you run from the trolling motor battery to the starting battery on the negative post I believe. It cleans up the interferance.

The system was working fine until I damaged the cable. I had heard others say then had problems, but I didn't have any interference until I crunched the cable.

      recommendation for first timers to northern Minnesota?  we need decent lodging, boat or sitontop kayak, smallmouth is our favorite but we will fish for anything that will bite artificial.  thanks in advance for any help.

      My Alaska trip fell through, so I'm thinking having never been to Minnesota that should be my destination. thinking a week in august. Probably start International Falls or Duluth. We need a resort with sit on top kayaks or aluminum boats, comfortable lodging without being plush and not ripping our heads off pricewise.  We will target Smallmouth, but if it will hit a lure I will fish for it. any recommendations would be greatly appreciated.

      Went out of Stoney Point sunday morning.  FYI Watch for deer almost smoked a few on the 20 mph section coming back into the access!  There is an ice heave forming off of the rocks going straight north.  If you want to fish Paris Trench people were crossing instantly using boards.  We weren't gutsy/brave/stupid enough to cross there since we were pulling a trailer behind a four wheeler and had 3 of us with all our gear.  The ice was sketchy from access to point at the point the ice heave goes a little further away from shore and it allows you some room to avoid the point's tip.  There is open water immediately around the point tip but ice looks great if you follow the tracks and avoid huging the tip.  We couldn't find a place to cross the ice heave to get to Paris Trench so we were going to try a few spots further north since we could see a few groups set up north a ways.  About 5.5 miles north of the access the ice heave quits and you can cross it without any worries.  Since we could cross the GPS spot we wanted to fish was only 2.5 miles away and we fished there.  Out in the middle we had 26-28" of ice and barely made it through.  While fishing a plane landed on the lake and a 1/2 ton extended cab pickup came from the NE some where, it was too foggy misty to see where and we didn't see him leave.  Coming back from Stoney Point's Tip to the access was very sketchy.  Made me nervous since there was a lot of slush and water but ice held us up.  If you plan on going out next weekend you may need to find a different access, or atleast I would!  Talked to a guy who came in behind us, they crossed the ice heave at the access using boards how they did and they said it was very slow and only got two.
