Installing Your Fishfinder
• DO NOT mount the transducer in the path of the prop on
single-drive boats. The transducer can cause cavitation
that can degrade the boat's performance and damage the
prop. On twin-drive boats, mount the transducer between
the drives, if possible.

Do not mount the transducer behind
strakes, rivet lines, struts, fittings, water
intakes or discharge ports.
Mount the transducer
parallel with the water line.
Make sure the transducer is below
water level when the boat is on plane
at high speed.
Apply marine sealant to all screw threads to prevent
water from seeping into the transom.
