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.
