Checking the Angle and Projection
•
Do not position the bow of the transducer lower than the stern
because aeration will occur.

•
Do not position the transducer farther into the water than necessary
to avoid increasing drag, spray, and water noise and reducing boat
speed.

1. Using a straight edge, sight the underside of the transducer relative to the
underside of the hull (see Figure 2-9 ). The stern of the transducer should
be 1–3mm (1/16–1/8") below the bow of the transducer or parallel to the
bottom of the hull.

2. Using the vertical adjustment space in the bracket slots, slide the trans-
ducer up or down (see Figure 2-10 ). Be sure the bottom left corner of the
transducer projections 3mm (1/8") below the bottom of the hull.
