2.5 Antifouling Paint

Marine growth can accumulate rapidly on the transducer's surface reducing performance within
weeks. Surfaces exposed to salt water must be coated with antifouling paint. Use water-based
antifouling paint only. Never use ketone-based paint, since ketones can attack many plastics
possibly damaging the sensor.
It is easier to apply antifouling paint before installation, but allow sufficient drying time. Reapply
paint every 6 months or at the beginning of each boating season. Paint the following surfaces
(see Figure 1):
 Outside wall of the insert below the lower O-ring
 Exposed end of the insert
 Paddlewheel cavity
 Paddlewheel
