Dave, If the old transducer is still good, it might work with the new sounder. Many are interchangeable. For the new one, I would make it flush with the outside of the hull with a good backing plate inside. Transducers beam is cone shaped rather than a pencil line. If it is not mounted perfectly straight down, it does not really seem to make that much difference. FWIW, I just returned from a boat delivery of a brand new trawler with no electronics at all. We scrounged up a used sounder and put the transducer in a plastic baggie of water in the bilge next to a stringer. Worked perfectly for 840 miles. Don, #6293, Niceville, FL

The other difference is the old was a mushroom thru-hull while the new is beveled. Some have suggested not beveling the bottom but just use a lot of 4200, one has suggested I see if I can find a mushroom thru-hull that will fit the new transducer, and two have said...just bevel the hole. Any opinions? I don't see why a mushroom thru-hull (if found) would affect the transducer...but could it. I know this isn't rocket surgery but I have a terribly bad habit of over analyzing everything before I do it...so any help (boat or psychological) will be appreciated.
