Transom TransducerInstallation

1. Locating the TransducerMounting Position

NOTE:If transom mounting is not possible because of a stepped hull or cavitation
noise, and you havea single layer fiberglass hull, In-hull installation is an option.
SeeInside the Hull TransducerInstallationfor more information.
Turbulence: You must first determine the best
locationon the transomto install the transducer.It
isvery importantto locate the transducerin an area
that is relativelyfree of turbulent water.Consider
thefollowingto find the best locationwith the least
amountof turbulence:
• As the boa t moves through the water,
turbulenceis generated by the weight of the
boat and thethrust of the propeller(s) - either
clockwise or counter-clockwise. Thisturbulent
wateris normallyconfined to areas immediately
aftof ribs,strakes or rowsof rivets on the bottom
of the boat,and in the immediate area of the
propeller(s). Clockwise propellers createmore
turbulence on the portside. On outboard or
inboard/outboardboats, it is bestto locate the
transducer at least 15" to the side of the
propeller(s) (see the illustration Turbulence-
FreeLocation).
• Thebest way to locate turbulence-freewater is
to viewthe transom while the boat is moving.
Thismethod is recommendedif maximum high-
speedoperation is a high priority.If this is not
possible,selecta location on thetransom where
the hullforward of this location issmooth, flat
and free of protrusions or ribs (see the
illustrationAreasof Possible Turbulence).
