Finalizing the installation
Follow the steps below to finalize the transducer installation.
- Apply a thick bead of marine-grade sealant in the gap between
the transducer and nose cone on the bottom and both sides, as shown
below:

- Remove any excess sealant on the outside of the hull and transducer, ensuring a smooth transition between nose cone and transducer, and transducer and hull.
- Ensure that the marine-grade sealant has fully cured.
Refer to the sealant manufacturer’s instructions for curing times.
- Anti-fouling paintUnless local environmental regulations prohibit, apply a water-based anti-fouling paint to the bottom face of the transducer, ensuring all of the externally exposed transducer surfaces are coated and the paint overlaps onto the hull.
- Check for leaks around the transducer immediately upon
returning the vessel back in the water.
CAUTION
Do NOT leave your vessel in the water unchecked after installing your transducer. Very small leaks may not be immediately obvious, and a considerable volume of bilge water could accumulate over the course of a day, or overnight.
- Continue to check for leaks at regular intervals after installation, until you are satisfied that there are no leaks.
- Add a regular check for leaks around the transducer to your routine vessel maintenance schedule.
