A transducer can not shoot through wood or metal hulls. Wood and metal hulls require either
a transom mount or "thru-hull" installation. For shoot-thru-hull applications many boat hulls
have a at keel pad that offers a good transducer mounting surface.
If you are using a Skimmer transducer versus a Pod transducer for this installation, make sure
the Skimmer transducer is oriented so the nose of the transducer is facing the bow (front) of
the boat. Also, if the transducer has a built in temp sensor, it will only show the temperature of
the hull, not the water temp.
Before you epoxy the transducer to the hull, make sure the area is clean, dry and free of oil or
grease. The surface of the hull must be at so the entire transducer face is in contact with the
hull. Also, make sure the cable is long enough to reach the sonar unit.
Sand both the inside surface of the hull,
where the transducer is to be epoxied,
and the face of the transducer.
Start with a rougher grit sandpaper, such
as 60 grit, and nish with a smoother
grit, such as 160 grit, sandpaper. Sand
the inside surface of the hull until it is
smooth to the touch.
The sanded area should be about 1-1/2
times the diameter of the transducer.
After sanding, clean the hull and face of
the transducer with an alcohol wipe to
remove any sandpaper grit and dust.
Apply a thin layer of epoxy (about
1-16" or 1.5 mm) on the face of the
transducer and the sanded area on the
hull. Make sure there are no air pockets
in the epoxy layers.
Press the transducer into the epoxy,
twisting and turning it to force any air
bubbles out from under the transducer
face. Stop pressing when it bottoms out
on the hull.

Apply pressure to hold the transducer in place while the epoxy sets. Be careful not to move
the transducer while the epoxy is setting. Allow the epoxy to set before moving the boat.
When nished, the face of the transducer should be parallel with the hull with a minimum
amount of epoxy between the hull and transducer. After the epoxy has set, route the transducer
cable to the sonar unit.
