Off today so could time to finally install this fishfinder! Based on
the followig pictu

I can either put the fishfinder at positions which I marked A or B.
I think B would be a perfect spot EXCEPT for the fact that, when it is
time to put the boat on the trailer and the end of the trailer is
underwater, there is a pretty good chance that eventually the
transducer would make contact with the (don't know what it is called)
"boat support beam" of the trailer (see how close it is). In theory,
this should not ocur if the boat follows the designated grooves created
by the side beams but ofen when it is still floating the back move side
to side until it eventually settles into the grooves.

So I am thinking A which is closer to the leg but I tried turning the
wheel all the way and the wires don't seem to touch the transducer
support bracket. Any obvious concern(s) with A that I might have
overlooked?

What do you people think? TIA ! Andre


Position "A" is too close to the outdrive and prop and may result in poor
readings.

"B" seems to be a better position to me.

All the water disturbance created by the prop goes from the prop back.
Think about it, the boat is moving forward. The pickup shoots down.



That's not what Hummingbird said when I installed my depthsounder and
transducer on my boat:

From http://www.humminbird.com/images/PDF/hdr600.pdf (page 5)
"As a boat moves through the water, turbulence is generated by the weight of
he boat, and the thrust of the propeller(s). This turbulent water is
normally confined in areas immediately aft of ribs, strakes, and in the
immediate area of the propeller(s). It is very important to locate the
transducer in an area which is relatively free of turbulent water. If the
prop(s) are forward of the transom, it may be impossible to find an area
clear from turbulence, and a different mounting technique should be
considered. On outboard or inboard/outboard boats it is best to stay at
least 15" to the side of the propeller(s)."
