Thanks for all the replies (which I have printed out and
studied.) I would certainly feel capable of removing the transducer
(which seems clearly to be the problem.) DMI Electronics (the
reincarnation of Data Marine) has the transducers for $150, and I have
actually seen them as low as $129.
Because the boat will have to be pulled ($150) in order to remove
the transducer (from the bottom), which would make total of $300, I am
looking at other options. Most obvious is to buy a new complete unit,
display and transducer. I'd like your opinion on a couple of points,
however, before I go that route.
(1) Some of these have "in-hull" transducers which are simply
epoxyed to the inside the hull. If these are accurate, they sound
appealing. Your thoughts?
(2) As I occasionally fish (but am by no means "avid") I am
wondering why I don't just buy a fishfinder. Some don't have
fractional readouts, and I would avoid those, but for those that
do read tenths of feet, is there any reason these would be less
accurate than a dedicated depth sounder? To get a good
depth sounder plus all the other features (including temp) is
very tempting UNLESS you tell me the depth sounders on these
are junk.
Again thanks for your past ( and possibly future) help.

You are never going to believe this, but when searching for the most
suitable place to locate an in-hull transducer, a British company found that
of the 15 or more different materials they tried for maximum sensitivity on
the transducer head, MARMALADE was far and away the best!

Most boats have at least a jar of marmalade in their food lockers. Save you
paying for exotic materials to do the same job!

Spread it thickly!
