I have no objection to a fish-finder type sounder. I would prefer not to make the hole any larger if at all possible. I have dreams of someday getting some 'real' electronics and mount them at the wheel. That way the holes could be covered up and passengers could properly lean against the bulkhead.
My make-shift solution is actually a fishfinder hanging on an unused knob and a transducer screwed to a stick that I tied off to the stern rail. It's rather unimpressive, but it works...

You may have a slight Impedance mismatch that could give a slight mis-read. But, it's likely that a NEW set will have an "offset" adjustment. You can adjust to Trim to the proper depth reading. May I offer a suggestion about covering the 4 inch hole in the bulkhead? Have you thought of a FISHFINDER /Sounder.? Many are large squares and likely could cover the bulkhead hole. Sometimes less costly than a "Yachtie" type ... and besides the Large Readout Depth numbers... You can often "See" the bottom conditions. IE: Soft pattern line, could indicate mud or weed bottom.... Hard line indicates Rock ...Etc... Besides... Finding fish....
