How to Install a Replacement Radio in My Pontoon Boat
- 1). Disable the power to the radio. Remove the faceplate and dash panels to access the radio. Pull the radio slightly out of the dash and unplug the antennae wire.
- 2). Pull the boat's radio wiring harness far enough out of the dash to access the old butt-splices. Note the color coding on the boat's wires and where they correspond on the radio. Cut the wires just behind the old butt-splices.
- 3). Strip 1/4 inch of insulation from the end of each wire on the boat's wiring harness and on the radio's wiring harness with the wire strippers. Crimp a butt-splice to each of the boat's wires with the terminal crimpers.
- 4). Slip the radio spacer over the radio from the back before connecting any wires. Test fit the new radio and spacer in the radio hole and make any adjustments to properly seat the radio.
- 5). Crimp each boat wire to its corresponding wire on the radio. Plug the antennae wire into the back of the radio, then slide the radio back into position in the dash.
- 6). Test the radio for proper operation, then reassemble the dash.
