NOTE: The transducer has a natural downward slant of 4-5 degrees from leading edge (closest to the boat transom) to trailing edge (farthest away from the boat). Looking at the back of the transducer, the seam should be slightly below the bottom of the hull.

7.Continue to adjust until the bracket is also level from port to starboard (horizontally level as you look at the transducer from behind the boat [Figure 24]).

8.Mark the correct position on the transom by tracing the silhouette of the transducer mounting bracket with a pencil or marker.

	9. Tighten the pivot bolt, using the pivot screw
	and nut to lock the assembly. Hand tighten
	only!
Figure 24	CAUTION! Do not use a high speed driver on this
	combination of fasteners. Hand tighten only.
	10. Hand-tighten the two mounting screws.
	NOTE: You will drill the third mounting hole and finalize the
	installation after you route the cable and test and finish the
	installation in the following procedures.
