How to Install a Humminbird Fish Finder

How to Install a Humminbird Fish Finder
Use a humminbird fish finder to maximize your time on the water. Locate schools of fish faster and more efficiently with the device. Pinpoint exact locations of schooling fish and drop your line into the water where you know you will have success. Install the fish finder properly before heading out for a day of fishing and being on the water.

Instructions

Difficulty: Moderately Easy

Transom

Step 1
Locate an optimal place on the boat to install the transducer (sonar wave emitting device). Find a place on the boat's underside where there is little to no turbulent water. Position the transducer within 15 inches of the engine props. Take the mountain plate and measure out the four holes where the screws fix it to the boat. Mark the holes. Drill the holes with the power drill. Place the mounting plate over the holes, then the transducer. Screw the four screws into the mounting plate with the screwdriver turning to the right until all four screws are firmly in place and the transducer set. Fill the screw holes with the silicone sealant and let dry.
Step 2
Attach the transducer pivot to the to the transducer body with the provided 8 mm screw from the installation kit. Tighten the pivot to the transducer body with the installation kit's Allen wrench. Insert the transducer into the mounting on the bottom of the boat.
Step 3
Unspool the fish finder cable and run the cable to the transducer. Decide if you want the cable running outside the boat along the combing (edge of where the boat meets the cabin) or run internally. Drill a hole next to the transducer if you decide to run the cable internally. Connect the cable to the transducer via the attachment point. Run the rest of the cable into the drilled hole. Run the cable along the combing if going externally.
Step 4
Measure where the outer transducer is in relation to the inside of the boat. Measure the same location inside the boat atop the bottom transducer location. Drill four holes with the mounting plate, set the plate onto the holes, then place the second transducer onto the plate. Screw the four provided screws into the four holes turning to the right until firm.
Step 5
Locate the mounting position for the display screen and control panel on the transom of the boat cockpit. Drill four holes measured by the mounting plates template. Drill out the four holes. Place the mounting plate over the holes, lining up the mounting plate holes. Place the display screen and control panel over the mounting plate. Screw the four provided screws into the display screen/mounting plate, turning to the right until all four screws are firm.
Step 6
Grab the cable, run it along the side of the boat and attach to the display screen and control panel. Take the power cable from the installation kit and run along the transducer cable to the boat engine battery. Attach positive wire to the positive terminal and the negative wire to the negative terminal. Screw the grounding wire to the battery's grounding terminal.
Step 7
Adjust the angle of the display screen to the desired setting for clear viewing.

Tips & Warnings

 
Take time to read the humminbird instructions and installation preparation documents before beginning any work.
 
Measure twice and drill once.
 
Disconnect all electric sources like engine battery before installing any cables or plugging any electric source in during installation.
