Maintenance, Repair, And Replacement; Transducer Specifications - Nexus STAR Einbauanleitung

MAINTENANCE
If the performance improves when turning, the transducer's position probably needs adjustment because it is
in aerated water. First move the transducer down 6 mm (1/4") farther into the water. If the performance does
not improve satisfactorily, move the transducer closer to the centreline. Fill unused screw holes with marine
sealant.
Note! To overcome the effect of surface roughness on an aluminium boat, it may be necessary to move the
transducer down so that it projects 15 mm (3/4") below the transom.

5 Maintenance, repair, and replacement

Aquatic growth can accumulate rapidly reducing the transducer's performance in weeks. Clean the assembly
with a soft cloth and mild household detergent. If fouling occurs, use a stiff brush or putty knife to remove the
growth being careful to avoid making scratches. In severe cases, wet sand the surface with fine grade wet / dry
paper.
If the paddle wheel becomes fouled or inoperable, it can be removed for cleaning. Gently push back on one
retaining arm and slide the shaft out. After cleaning, reinsert the shaft by pushing back on the retaining arm. Be
sure the shaft ends are secure in the retaining arm notches.
Antifouling paint
Surfaces exposed to salt water that do not interlock, should be coated with antifouling paint. Use water based
antifouling paint only. Never use ketone based paint since ketones can attack many types of plastic. Apply paint
every 6 months or at the beginning of each boating season.
Parts and accessories
Broken or worn parts should be replaced immediately. The water-lubricated paddle wheel bearings have a life of
up to 5 years on low-speed boats (less than 10 knots) and 2 years on high-speed vessels.
