NOTE: On boats with more than 15 degree deadrise angle it may be necessary to mount the 
transducer slightly off parallel with the water level. (See Figure E) 
 
Mark and drill the three 9/64” dia. holes as shown on the template. Attach the metal bracket using 
the three #10 self threading screws supplied. Be sure to align the holes so that they are centered 
vertically in the three slots found in the bracket. It is important to use a silicone sealant between 
the screwhead and bracket in order to prevent leaking. 
 

 

 
Step 3. 
TRANSDUCER PIVOT ASSEMBLY- Assemble the pivot to the transducer main body using the 
two ¼”x5/8” allen head screws, two 3/8” tooth washers and two, ¼” square nuts. Make sure the 
tooth washers are sandwiched between the transducer main body and the pivot. The square nuts 
are trapped inside the pivot and will not rotate as the allen head screws are tightened. 
HOWEVER, DO NOT TIGHTEN AT THIS POINT. (See Figure F)
