Mine sits in a baggy of water on the inside of the hull in front of the keel
where my head thru hull is located. I just need to make sure the bag has
water. I tried mounting with an adhesive but couldn't get it to work. Perhaps I
had an airbubble or something. I'll mount it securely one of these days.

Subject: [Cal_Boats] Installing fish finder
I picked up a Lowrance X-4 Pro Fish Finder and wanted to install it on my Cal
2-29. The directions state that the bracket should be attached to the transom
and the skimmer placed so that it was about halfway in the water. Problem is
that my rear is too far out of the water for that to work.
The diagrams in the manual show the device can be attached to the bottom of a
trawler motor. So I wrote to Lowrance and asked if it could be mounted forward
of the prop, with the bracket underwater. They replied that it wouldn't work due
to possible cavitation issues. Now, I'm not sure how I'm going to get air down
under the boat, but maybe I'm not understanding.
My question: has anyone on the list had experience installing this device
somewhere besides the transom?

Hello Anne,
You don't want to stick a bracket down off the transom, it will just snag debris
when underway. On my Cal 29, I installed my transducer aft of the keel
immediately to the left of the aft bulge compartment on the inside of the boat.
I simply took some marine sealant and after cleaning both surfaces well with a
little acetone, I mated the transducer to the hull with white marine sealant..
Works like a charm. I've done this on both of my Cals that I've owned and it
worked both times.
Its not as good for finding fish when mounted this way, but it sure beats the
standard depth sounder that came with the boat.
Good luck,
Frans

Does anyone know if this technique will work through a wood hull, like say 1
1/2 inch of Mahogany?

Nope, but it is a sound transmission thing... so I would expect it to probably work, but with decreased power thorough porous wood verses dense GRP.

I mounted a thru-hull transducer in the same manner as Frans, except that I used West System Epoxy. I used epoxy because I thought it would transfer more sonar and make a thinner bond and it is easily removed (small chuckle) should the puck fail or end up in the way later. I tested the location very thoroughly with a baggy full of water under the puck before I settled on the final installation. Sounds like Frans and I settled on the same location. As for the epoxy; I stirred the mix very slowly to avoid bubbles and let it settle before I gently twisted the puck into position. I had hot-glued a cardboard "damn" as a positioning bracket and so that the weight of the puck didn't smear the epoxy down the slight curve of the bottom of the hull. Please note that it easy to remove the puck as long as you don't want to use the puck ever again -- need a 4" angle grinder and a cutting disc.
Note that I used a puck with a beveled face, that was specifically designed for thru-hull use. The bevel allows you to rotate it until it lines up level, compensating for the rise of the hull. You do this and mark it before applying epoxy, of course. I get sonar returns down to 500 feet or so, depending on a variety of factors. I have yet to care too much how deep it reads after about 10 feet under the keel, except for coastal navigation with a chart -- reading contour depths has some value. With three GPS on board I am getting sloppy about that art -- probably have forgotten more than I once knew. ?

When I was fishing (tunas) and cruising from my boat more than I was racing, I bought a Garmin Fishfinder. I bought the dual cone model to 1000 ft. I asked Garmin about mounting it to the inside of the hull and they replied with what Wilkie has done. It was suppose to be good down to 900 feet. I didn't get to mount it yet. I am racing now more than I am fishing.
Someday!

I installed a Standard DS, but I put mine forward, under the V berth. Standard made a mount just for that purpose. The most important part was determining the hull deadrise. I must have gotten close because it works! I don't think Standard makes DSs anymore. I just don't like putting holes in the bottom of my boat.
