I plan on installing a depth sounder with a in hull puck transducer. Has
anyone installed one of these and if so can it be tested out of water?
I'm going to install it on my boat in my driveway and want to test the
position before I epoxy it down.

Thanks

The only way to do it is on water. This is what you need to do:

Get a sand bag or something similar to weigh down the transducer where you
think you want it, and flood the bilge so it covers the transducer. Now
motor around and look at the readings. If they seem spotty, or inacurrate,
then move the puck to a different spot. Keep doing this until you're happy
with the readings, and mark the spot. Now you can work in your driveway. :-)

Remember to use SLOW setting epoxy (4hrs or more) when you glue the puck in
place, and use a lot of it. The slow set allows most air to escape while
curing. Air is bad when between the transducer and water.

Good luck.

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?

Just in case you aren't aware, it will not work at all thru metal hull.

Thanks for all the replies. It's a fiberglass hull. I actually went to
the factory when they were building it and they showed me where they
double lap the glass.

I don't want one to hang off the stern because it would just look
cleaner being hidden. Just looks that's all. If I can't get the puck to
work I would probably buy one.

The sounder is just a depth sounder not a fish finder/sounder. I like
the idea of the bag of water.

I'm going to call the dealer and see what their experiences with this
boat are. Maybe they can point me to a spot that has worked for them in
the past.

Thanks again.

Larry, mine is off the stern. Once the boat is in its natural habitat,
i.e., water, the stern mount is not noticeable at all.
