How to install a fish-finder on your boat


Irrespective of the kind of fisher you are, a fish finder definitely makes your work easier and resourceful. You should be acquainted with proper instructions about the location and the position of the fish finder before finally installing it on your boat. It comes with a factory made standard transducer which you can use to install it on your boat that can be exchanged as per the needs of the fisher.


  1. Determining the correct position to mount the transducer: It is the primary and the most important step of the installation process. It is very essential to locate the transducer in an area which is relatively free of water turbulence. However, on the boats with stepped hulls, it is recommended to mount the transducer on the step. The proper position of the fish finder is the right way to have a profitable fishing excursion.


  1. Drilling the mounting Holes: Hold the mounting template on the transom of the boat in the location set to install the transducer. By using a pencil or punch and a drilling machine, mark and drill the two mounting holes respectively.


  1. Mounting the Transducer: After properly inspecting and locating the transducer and keeping in mind that the transducer must be in contact with water, you can also glue the transducer on the inside of the boat hull. After applying silicone sealant to the holes drilled, align the transducer assembly with the drilled holes in the transom. Then by using a flathead screwdriver tighten the mounting screws in order to vertically adjust the transducer.


  1. Adjusting the Position of the Transducer: After mounting the transducer next step is to adjust its height and angular position. This position is often referred to as the “running position” of the transducer. This can be done with the help of wrenches which are used to adjust the pivot screws present in its assembly according to the needs of the person.


  1. Routing the Cable: This is the second last step of the installation process. Out of several methods to route the cable, the most common procedure is the one that routes the cable through the transom hooked on to the boat. Routing is done in the area where the control head is planned to be installed. The complete steps include:
  • Drilling a hole near to the water line
  • Routing the cable through it
  • Filling the hole with silicone sealant
  • Securing the cable by attaching the cable camp to the transom by using a screw of appropriate size


  1. Installation of the Control Head: The cables and speed/temperature accessories should be installed before finally installing the head piece.
