Airmar Shorty P6 Owner's Manual & Installation Instructions

OWNER' S GUIDE
Shorty Thru-Hull Depth Transducer
™
Low Profile, Flush, and Retractable Models:
P6, P7, P8, P206, P207, and P208
IMPORTANT : Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
CAUTION : NEVER USE SOLVENTS!
Cleaners, fuel, paint, sealants, and other products can
contain strong solvents, such as acetone, which attack
many plastics greatly reducing their strength.
Applications
• Recommended for fiberglass or metal hulls only
• Never install a plastic thru-hull housing in a wood hull, since
swelling of the wood can possibly fracture the plastic.
• Low profile housing recommended for cruising sailboats and
planing hull powerboats
• Flush housing recommended for racing sailboats and high-
speed powerboats
• Hull deadrise angle should not exceed 20º

Mounting Location
Placement
Choose a location:
• Where the transducer will be continuously immersed in water.
• Where the water flowing across the hull is smoothest with a
minimum of bubbles and turbulence (especially at high speeds).
• Where the transducer beam will be unobstructed by the keel or
propeller shaft(s).
• Away from interference caused by power and radiation sources
such as: the propeller(s) and shaft(s), other machinery, other
echosounders, and other cables. The lower the noise level, the
higher the echosounder gain setting that can be used.
• Where there is a minimum deadrise angle, not exceeding 20º,
so the transducer beam will be aimed toward the bottom.
• Where there is adequate headroom inside the vessel for the height
of the housing, tightening the nuts, and removing any insert.
