Uniden MC 800 - Manual (Page 18)

Installation-Thru-Hull Mount
Drill a hole in the bottom of the boat large enough to accomodate
the stem of the transducer. Use fairing blocks to "sandwich” the
transducer and to waterproof the area of installation. By shaping the
fairing block located beneath the hull, you can reduce the amount of
drag on your boat. This is the best mounting for obtaining maximum
performance from your system, however, there are also disadvantages
to this type of mount, such as;
• Damage can be caused to the transducer and/or hull when load­
ing or unloading your boat from a trailer.
• Damage or sinking can occur if the transducer strikes a submerg­
ed object while boating.
• Barnacles and other marine life will attach to and grow on the
transducer impairing performance.
■ This type of mount will cause noticeable drag on high perform­
ance hulls.
