In the fall, I bought a FF Garmin 120 and been procrastinating all
winter regarding installing it. Now I want to put the boat back in the
water so it is time to get on with it !

I am looking at the instruction sheet but because it is in 2D instead
of 3D, it is hard to tell from the picture where the tranducer should
be (relative to the bottom of the transom).

Should it be:
1) flush with the bottom of the transom?
2) an inch or more above the bottom of the transom?
3) an inch or more below the bottom of the transom?

Some of the guidelines provided:
"The transducer has to be located in clean (non-turbulent water). The
transducer should be located as near the centre of the boat as
possible"

Sometimes (as with my boat), it's not possible to find a spot that's not
near non-turbulent water. So, I can't trust any of my readings above a
certain speed.


"Mount the tranducer parallel with the water line" (this is one that I
find confusing since the picture with this caption points to the
bottomof the transom).

They really do mean parallel to the water line.

Although the instructions suggest that this installation is neat and
orderly, it's really not. First, you can't get a good idea of position when
you're leaning over the back of the boat. A better way is to anchor in
shallow water, jump in, and make the necessary marks on the transom with
nobody in the boat. Or, lean over the edge of the dock. Whatever works.

My fishfinder's bracket has elongated holes for the mounting screws, so the
unit can be slid up & down for fine adjustment. Even so, I wanted more
"travel", in case I needed to move the thing more than the length of those
holes. So, I mounted a piece of Starboard (plastic, sort of like the white
cutting boards for kitchen use) to the transom, and made elongated holes in
that. This way, I only had to drill the transom once. Between the two sets
of elongated holes, I have almost 4" of adjustment available.
