transducer mounting
 

I have an aluminum boat. I want to purchase a fish/depth finder for it. I am
cautious about drilling holes in my perfect aluminum hull. Is there another
way to mount it? Epoxy perhaps? Silicone? What have others done?

The transom of my Lund is aluminum, single layer. I figured that corroding
hardware would develop gaps which could contribute to leakage, so I used
stainless steel hardware. (This should be obvious anyway). I made the holes
slightly larger than the bolts and filled them with silicone caulk before
inserting the hardware. A day later, I added a thin bead inside & out around
the bolt head on one side and the nut on the other. In 4 years, no leakage.

By the way, choose hardware with smooth edges, like acorn nuts on one side
instead of an exposed bolt shaft. Easier to clean around them, and less
chance of slicing hands & feet on rough edges.

Finally: If your mounting bracket has slotted mounting holes so you can
slide the thing up & down a little to adjust height, fine. If not, you may
want to begin by mounting a small piece of wood to the boat in roughly the
right place, so you can drill a series of holes in the wood as you
experiment with the right height for the transducer. The guidelines in the
manufacturer's manual are just that: guidelines. It took me a few trips on
the water to get the position just right.

you can get a bracket welded on the transom and mount the transducer on
that

If you can find a block of PVC plastic, you could glue that to the hull
and then mount your transducer to the PVC. Other materials could also
be glued to the hull with Marine Goop, about $3 a tube. I mounted my
fish finder transducer to a piece of 1X2 about 15 inches long, and I C-clamp
it to my hull about 6 inches to the side of my outboard.

I've used a block of starboard and 5200 to secure a place to mount a
transducer, but that's kind of silly.

Drill the freakin' holes, mount the transducer with stainless steel
screws, washers and stop nuts, use a little silicone sealer and be
done with it.

Thanks to all who offered advice. I like the PVC with GOOP idea. I
might try it.

a block of PVC.. does H.D sell that? I only see PVC pipe these days...

PVC cutting boards (like you use in the kitchen) will work nicely. For more
thickness, stack 2 and epoxy the bejeezus out of them.

Amazing stuff Starboard, huh?

It does seem to be identical to cutting boards, doesn't it? :-) Slap on a
fancy name, call it a boat product, and now it's two bazillion bucks a
sheet.
