Positioning the Transom-Mount Transducer

Follow these instructions if you are installing the transom-mount
transducer.
Begin by finding the best location for the mounting bracket. Here are the
rules:
• If your boat has one propeller (outboard or inboard-outboard), mount
the transducer about 18" (455 mm) to the side of the centerline of the
boat. See Fig. 2-7. Choose the side that is on the downstroke of the
propeller. (This is usually the starboard side of the boat.) This will
reduce any interference caused by air bubbles.
• If your boat has twin propellers (outboard or inboard-outboard), place
the transducer near the centerline of the boat.
• If the propeller can be turned to steer the boat, allow at least 2" (50
mm) beyond the swing radius of the propeller. This will prevent the
propeller from damaging the transducer when it is turned.
• Do not mount the transducer behind any hull fittings, intakes, or other
parts which extend from the hull. These may cause turbulence or air
bubbles.
• The bracket has a quick-release mechanism. This prevents damage
by allowing the transducer to flip up if it hits any debris or the bottom.
See Fig. 2-8. Allow enough clearance above the transducer so that it
can swing upward completely. This is about 10" (254 mm) measured
from the bottom of the transom.
• If the boat will be carried on a trailer, be sure the transducer will not hit
any rollers, bunks or fittings on the trailer.
