Transducer On A Trolling Motor, Why?!

In order for your fish finder to work correctly, the transducer should be in the water at all times. This lets the transducer send more accurate signals back to your fish finder so that you can understand the underwater landscape, the location of the fish and the depth and/or temperature of the water.

Mounting the transducer to your trolling motor can be more convenient as it can mean the transducer maintains its position under the water. It can also mean you don’t have to mount it to your transom or through the hull of your kayak, which could save you from drilling holes in your boat.

What Type Of Transducer Mount Do I Need? (the best)

To securely attach a transducer to a trolling motor you will need a trolling motor mount. There are various mounts available with many designed to fit a range of trolling motors. However, it’s worth checking that the mount will work with your particular motor and transducer, as they may not all be compatible.

The mount means your transducer can be safely attached so that it stays in place, giving you accurate readings.

Step 2: Attach Your Hose Clamp

Your hose clamp should be included with your mount kit. Slot this through the port on the transducer mount until the hose clamp is the same length on either side.

Step 3: Mount The Transducer To The Trolling Motor

Now you can place the transducer mount under the motor, between the fin and the propeller. Make sure the narrower end of your transducer is facing away from your propeller.

Holding the transducer mount against the body of the motor, fix the hose clamp around the body and tighten it using a screwdriver.

Step 4: Secure The Cables

Using the included cable ties, secure the cable from your transducer along the length of the shaft of your motor, making sure the cable is out of the way of the propeller  and anything else that could affect the running of either your motor or the transducer.

The transducer cable can then be connected to your fish finder.

Final Words

Knowing how to mount a transducer to your trolling motor can give you another way of using your fish finder without having to drill into your boat. It can be a good idea to make sure the trolling motor mount kit you choose is compatible with both your transducer and your trolling motor.
