Surface:
The mounting surface must be flat and approximately parallel with the boat’s water line.
Surface Thickness:
The mounting surface must support the weight of the scanner. The
recommended surface thickness is 3/8 to 1/2 in (9.5 mm to 13 mm). If the mounting surface is thin,
a doubler should be added. If it is thicker than recommended, longer bolts must be purchased
separately.
CAUTION!
The scanner will be damaged if the bolts protrude more than 1/2 inch (13 mm).
Access:
Access to the under side is required for installation of the mounting bolts.
Cable Routing:
Test the cable route from the scanner to the control head and power location. Avoid
routing the interconnecting cable through areas of possible damage, from moving objects, machinery,
exposure to chemicals, or high temperature. See
Installation: Connect Power
