transducer mounting question

[Bob1757]

transducer mounting question i want to mount a depth sounder (display has two docks (one for cabin, one for cockpit))the transducer is a skimmer type (low drag, not through the hull though.)i would like to mount the transducer forward of the keel, so i can see what i'm about to hit + not what i just hit.does anyone have experience / thoughts on the idea of: running the cable over the transom, then forward along the bottom, parralel to the keel/hull joint, then attatching it a foor or so forward of the keel. cable has to travel aft due to way cable comes out of transducer.any ideas on what adhesive would be best? i plan to use marine goop to hold the cable tight to the hull + transom.

Try this

I think trying to glue the transducer and cable to the bottom of the boat is asking for future headaches. You may be able to mount it internally, if your hull is solid fiberglass (non-cored). If you can get access to the area forward of the keel you can use epoxy to glue it to the inside of the hull. The epoxy has the same density as water and the transducer signal will shoot right through a solid non-cored hull w/o a problem. You won't have a problem with bottom growth, drag, knocking off the transducer, or the cable coming loose. I just did this on my 22 with a Pirahna fishfinder and it works very well. Be sure to use long-set epoxy - the short set stuff cures too quickly and will trap air bubbles, a definate no-no for tranducer performance.
