•On boats with stepped hulls, it may be possible to
mount the transducer on the step. Do not mount the transducer on the transom behind a step to avoid popping the transducer out of the water at higher speeds; the transducer must remain in the water for the control head to maintain the sonar signal.
Deadrise Angle
•If the transom is behind the propeller(s), it may be impossible to find an area clear from turbulence, and a different mounting technique or transducer type should be considered, such as an Inside the Hull Transducer (see Inside the Hull Transducer Installation).
•If you plan to trailer your boat, do not mount the transducer too close to trailer bunks or rollers to avoid moving or damaging the transducer during loading and unloading of the boat.
•If high speed operation is critical, you may want to consider using an
NOTE: The hydrodynamic shape of your transducer allows it to point straight down without deadrise adjustment.
NOTE: If you cannot find a transom mount location that will work for your
2. Preparing the Mounting Location
In this procedure, you will determine the mounting location and drill two mounting holes, using the transducer mounting bracket as a guide.
1.Make sure that the boat is level on the trailer, both from port to starboard and from bow to stern, by placing your level on the deck of the boat, first in one direction, then in the other.
2.Hold the mounting bracket against the transom of the boat in the location you have selected. Align the bracket horizontally, using the level; make sure that the lower corner of the bracket does not protrude past the bottom of the hull, and there is at least 1/4" clearance between the bottom of the bracket and the bottom of the transom for fiberglass boats, and 1/8" clearance for aluminum boats.
