Instructions for a Ray Jefferson Fish Flasher

The Ray Jefferson Fish Flasher came in a variety of models to accommodate different fishing styles, but all include the transducer, which is mounted on the outside of the boat transom, and the fish flasher itself, which has a rotary dial that provides a depth reading from the transducer to the lake bottom. Once installed, the flasher is connected to your boat's battery for a power source.

Instructions

    • 1

      Position the transducer on the transom of your boat at a point just below the waterline. Mark with a pencil where the two mounting holes are located, and then drill out the holes with a small drill bit. Drill a third hole through the hull between the two mounting holes to accommodate the wires for the transducer.

      Insert the transducer wires through the center hole, and then apply a coat of silicone sealant to the back of the transducer where it will meet the hull of the boat. Line up the mounting holes for the screws.

    • 3

      Secure the transducer to the hull of the boat with the screws, ensuring that the silicone sealant extrudes from the side of the transducer when the screws are tightened.

    • 4

      Route the wires from the transducer under the boat's gunwale to the position of the Fish Flasher. The unit should be in a place where you can easily see it from the helm of the boat.

    • 5

      Connect the electrical leads on the flasher to the boat's battery's terminals. This is done by loosening the battery terminals and sliding the fish flasher's wires underneath. Once you have tightened the battery terminals, the installation process is complete.
