How to Install Airmar P155C-M In-Hull CHIRP

Proper installation is crucial for optimal performance of the Airmar P155C-M In-Hull CHIRP. This transducer is designed to be mounted inside the hull of fiberglass boats, requiring a smooth, clean surface area for best results.

Before installation, clean the hull surface thoroughly and ensure the area is free of paint or gel coat defects. Use marine-grade epoxy or the recommended adhesive to bond the transducer securely. The Mix-N-Match plug facilitates easy connection to your sonar or chartplotter system, but always verify compatibility beforehand.

Installation Tips for Optimal Performance

Choose a flat hull surface away from turbulence or prop wash.
Ensure no air pockets exist between the transducer and hull.
Follow manufacturer torque recommendations for mounting hardware.
Check cable routing to avoid interference and damage.

Maintenance Tips

Maintaining the Airmar P155C-M In-Hull CHIRP transducer ensures long-term reliability and accuracy. Unlike external transducers, the in-hull design protects it from direct exposure to water, reducing fouling and physical damage risks.

However, regular hull inspections should include checking the transducer mounting area for any signs of delamination or damage. Clean the hull surface to remove algae or debris buildup that could affect sonar signals.

Routine Checks and Troubleshooting

Periodically inspect the Mix-N-Match plug for corrosion or loose connections. Any signal irregularities often result from wiring issues, so ensure all plugs and cables are secured and dry.

If you experience signal loss or erratic readings, verify the adhesive integrity and reapply if necessary. Also, confirm that your marine electronics firmware is up to date for best compatibility with the CHIRP transducer.
