threaded section as close to the top of the nut as possible. The wire
should then be tied to prevent it coming loose.

20. Remove any excess sealant on the outside of the hull and transducer,
ensuring a smooth transition between the transducer and hull.
21. Ensure that the marine-grade sealant has fully cured
Refer to the sealant manufacturer's instructions for curing times.
22.Unless 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.
23. Check for leaks around the transducer immediately upon putting the
vessel back in the water.
Important:
Do NOT leave your vessel in the water unchecked after installing your
transducer. Very small leaks may not be immediately obvious, and
considerable bilge water could accumulate over the course of a day, or
overnight.
24. Check for leaks at regular intervals after installation until you are satisfied
that there are no leaks.

25.Ensure checking for leaks around the transducer is added to your routine
vessel maintenance schedule.

Anti-fouling

Where local regulations allow, it is recommended that you coat your
transducer using a water-based anti-fouling paint. This will help prevent the
build-up of organic growth, which can reduce transducer performance.
Important:
• Before applying water-based anti-fouling paint, check that local
environmental rules and regulations do not prohibit the use of anti-fouling
paint.
• Never use copper-based anti-fouling paint as this can impact transducer
performance.
• Never use ketone-based anti-fouling paint as this can attack the
transducer's plastic, damaging the transducer.
• Paint your transducer using a brush, do not use a spray can or a sponge
roller as these methods can cause tiny air bubbles to be incorporated in
the paint, which will also reduce transducer performance.
The anti-fouling paint should be applied in a thin and even coat covering all
externally exposed transducer surfaces.
You should clean your transducer regularly and re-apply anti-fouling paint
every 6 months, or sooner depending on how rapidly organic growth builds
up.
