INSTALLATION 

INSIDE THE HULL INSTALLATION 

 

3.  Power up the Control Head. 

 

4.  Run the boat at various speeds and water depths while observing the screen 

on the Control Head. If the unit functions well at low speeds but begins to skip 
or miss the bottom at higher speeds, the transducer needs to be moved. If 
depth performance is required, test the fishfinder in water at the desired 
depth. Test different locations in the hull until the optimum performance is 
achieved. 

 

Step Three - Permanently Mount the Transducer 

 

1.  Once the mounting location is determined, mark the position of the 

transducer. 

 

2.  Remove the water from inside the hull and thoroughly dry the 

mounting surface. If the surface is excessively rough, it may be 
necessary to sand the area to provide a smooth mounting 
surface. 

 

Ensure the mounting area is clear and dry. 

 

3.  Mix an ample quantity of two-part slow-cure epoxy slowly and 

thoroughly. Avoid trapping air bubbles. 

 

4.  Coat the face of the transducer and the inside of the hull (Figure 

16). 

 

5.  Press the transducer into place with a slight twisting motion to 

purge any trapped air from underneath, keeping the pointed end 
of the transducer body pointed forward (Figure 17). 

 

Note: Proper operation requires the pointed end of the 
transducer body to face towards the bow. 

 

6.  Weight the transducer so it does not move while the epoxy is curing. 

 

When the epoxy cures, no water is necessary inside the hull. Neither water, 
spilled gasoline, or oil will affect the performance of the transducer.
