Step 4: Install Two Through-Hull Fittings In Front of Gear Trac
- First hole is for the transducer cable.
- Second hole is for the power cable, which runs to the battery
- Drill two 1-inch holes 1 inch apart through the hull in front of the Gear Trac.
- TIP: Reach through the front hatch while drilling to hold your rudder cables away from drill area. You don't want to cut those cables with the bit.
- Clean the loose plastic from the holes with a razor blade
- Slide a through-hull fitting nut over the transducer cable.
- Reach through the hatch to thread the cable up through the hole.
- Slide a rubber O-ring over the transducer cable and place on top of the hole.
- Pop the through-hull fitting gasket onto the cable.
- Pop the gasket into the through-hull fitting and push it tight with a screwdriver.
- Push the fitting down into the hole.
- Reach up through the hatch to tighten the nut onto the fitting.
- Pull the remaining transducer cable toward the front hatch and secure it with zip ties.
- TIP: NEVER cut a transducer cable to fit the length you're working with. Cut transducer cable does not function.
- Repeat this process for the power cable. Use a two-hole gasket for your through-hull fitting if your power cable has dual wires.
