In this Outdoor Recreation video tutorial you will learn how to mount a fish finder on your kayak. There are many ways of doing this. All the methods work. It‚Äôs just a matter of personal choice where you want to mount it. Some boats are designed for a through hole transducer and have a space for it to mount it in a hole. Take a piece of foam, trace out the transducer and cut out the foam. Now open the front hatch of the boat and glue down the foam on the flat surface of the boat. Once that is set, fix the transducer on the foam with Lexel sealant. Now run the power cable up to the display unit fitted on top of the second hatch. There is nothing complicated about this.
