CAUTION:
The arrow on the fairing always points forward towards the bow.
Be sure to orient the fairing on the band saw so the angle cut
matches the intended side of the hull.
3. Place the fairing on the table so the cutting guide rests against the fence. The
arrow/blunt end will point toward you for installation on the port side and
away from you for installation on the starboard side of the boat.
CAUTION:
Always wear safety goggles and a dust mask when drilling.
4. Recheck steps 1 through 3, then cut the fairing.
5. Shape the fairing to the hull as precisely as possible with a rasp or power tool.
Antifouling Paint
Marine growth can accumulate rapidly on the transducer's surface, reducing
performance in 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 transducer.
Reapply paint every six months or at the beginning of each boating season.
It is easier to apply antifouling paint before installation, but allow sufficient drying
time. As illustrated in Figure 2-12 , paint the following surfaces:
Exposed area of the housing, including the acoustic window
Bore of the housing up to 1-1/4" (30 mm)
Outside wall below lower O-ring
Exposed end of the paddle wheel insert
Paddle wheel cavity
Paddle wheel
Blanking plug below the lower O-ring and the exposed end
