I'm going to install it on my boat in my driveway and want to test the

I've done a few of these and can tell you, the effort isn't worth the
results.

However, you need to be aware of a few things.

Depending on the hull style, a through hull mount might not work
properly. For instance, if you have a sharp deadrise (deep vee), it
will be hard to find a place to mount the puck at a 90 degree angle to
the water - meaning that it shoots straight down instead of at an angle.

Second is finding a spot on the hull to mount it. You need to avoid
spaces between stringers, stringers and areas where there might be
excess eposy or glass. Make sure the only space between the water and
the transducer is hull.

Now, as to testing - yes, you can test out of the water. As Mike said,
use a heavy weight like a sand bag or similar kind of device and move
the puck around to find a solid return from your driveway without much
noise.

Use a slow set epoxy and mix it really well - slowly as you don't want
to introduce air to the epoxy.

Now, for the question of the day.

Is there a reason you don't want to hang it off the stern?
