Hello Dennis1022
I have a 24 volt and seperate the batts to charge.
As for the transducer cable, put your motor in its lock down position and see how much clearance you have between the shaft and the bracket.
Zip ties or hose clamps have been used in most case's.

Assuming that you are charging with a 12v charger, I would disconnect the jumper between the batteries and charge each one separatly. Most fishermen install a 2 or 3 bank charger that will charge multiple batteries at once. as far as the transducer wiring, try securing the cable with the motor in the stowed position and allow enough slack for the motor to deploy.

I'm a big fan of the 3 bank charger. I too have a 24v trolling motor, and the 12volt starter for the outboard. At the end of the day, just plug the charger into an outlet and it will charge all three batteries. Nothing to connect or disconnect other than the extension cord you run from your house to your boat.

Disconnecting the batteries each time you charge is a pain in the butt. You should get an onboard charger 2 bank of you only have 2 batts a 3 bank if you have 3 batts. It is alot easier that way. Both BPS and Cabela's have inexpensive model's

As for the transducer cable, you can run the cable in the stowed position just make sure you leave a loop in the cable where the inter shaft goes into the outer shaft to allow for the shaft to rotate 360 degrees without putting strain on it.

Thank you all for the information, I will check into all the recommendations.

I've rigged several transducers to trolling motors.  I do it with the motor in the deployed position.  First mount the transducer, then start winding the cord up the shaft maybe 4 to 6 times around.  Leave some slack at the junction of the upper and lower shaft so that the lower end is free to move fully in both directions.  I start at the bottom and use either electrical tape or wire ties to secure the cord to the shaft every foot or so.  From there it depends on what kind of trolling motor you have - hand controlled, foot controlled cable steer or electric steer.  With foot controlled units, I route the transducer cable on down the cable towards the foot pedal and then to the depth finder.  Regardless, route the transducer cable as best you can to the depth finder leaving enough slack to raise and lower the unit.  I use a little tape to hold the cable temporarily until I'm sure that everything is right and then do the permanent attachment.

As far as charging batteries goes I've done it both ways - single charger and dual or three bank.  Obviously, the multiple bank is easier and quicker.  If using a single charger, it's not necessary to unhook the battery cables, but you should unplug the trolling motor.  Good luck!
