screws allow angular adjustment. Correct transducer height and
running angle settings are needed to ensure best performance
at all boat speeds. Initially, adjust the transducer as described
in the following paragraphs. Further adjustment may be
necessary to tweak the installation after high speed testing.
1. Cut out the correct transducer template for your transducer
type from this sheet, following the cutting directions on the
template for your type of boat hull (aluminum or fiberglass).
Adjust the height on the transom and the pivot bolt angle to
match guides on the template as shown.
2. Hand tighten the pivot bolt and mounting screws at this time.
