3Transom Mount Transducers Installation Manual NAVMAN
Important
It is the owner’s sole responsibility to install and use NAVMAN’s transducers in a manner that will
not cause accidents, personal injury or property damage. The user of this product is solely
responsible for observing safe boating practices.
Transducer installation: The choice, location and angle of the transducer is the most critical part
of installation. If installation is not correct, the unit can not perform at its designed potential. If in
doubt, consult your NAVMAN dealer. Ensure that any holes cut are in a safe position and will not
weaken the boat’s structure. If in doubt, consult a qualified boatbuilder.

Position of transducer
Transom mount transducers are suitable for planing hulls less
than 26 ft (8 m) long, with outboard or stern-drive power. They
areunsuitable for boats with propellers forward of the transom,
prominent keels or displacement hulls.
Select a position for the transducer that will:
• Be away from the propellers or propeller wash and on the
downstroke side of the propeller/s (normally the starboard
side).
• Have a smooth, clear flow of water at all times, which
means that the transducer should not be in line with
any hull projections, openings or planing strakes.
