5. Attaching transducer to transom.
Attach the transducer to the transom. Slide the transducer up or down
until it's aligned properly with the bottom of the hull. Tighten the
bracket's mounting screws, sealing them with the sealant.
Adjust the transducer so it is parallel to the ground even if you have
a Deep-"vee" hull. Tighten the nut until it touches the outer washer,
then add 1/4 turn.
Don't over tighten the lock nut! If you do, the
transducer won't kick up if it strikes an object in the water.
Caution:
If you need to drill a hole in the transom to pass the connector
through, the required hole size will be 11/16" (17.5mm). If you
drill the hole, make sure it is located above the waterline. After
installation, be sure to seal the hole with the same marine grade
above- or below-waterline sealant used for the mounting screws.
6. Route the transducer cable through or over the transom to the NMEA
2000 network. Make sure you leave some slack in the cable at the
transducer. If possible, route the transducer cable away from other
wiring on the boat.
Align transducer centerline with hull bottom and attach transducer to
transom. Rear view of Skimmer shown.
7. Make a test run to determine the results. If the bottom is lost at
high speed, or if noise appears on the display, try sliding the
transducer bracket down. This puts the transducer deeper into the
water, hopefully below the turbulence causing the noise.
WARNING:
Clamp the transducer cable to the transom close to the
transducer. This can prevent the transducer from
entering the boat if it is knocked off at high speed.
