I had to replace a malfunctioning depth transducer back in the spring.
I started by trying to remove the old transducer but it was more than a
little resistant with copious 5200 type sealant around it and 35yrs to
harden. I needed to drill out a larger thru-hull for the new transducer
and was trying to figure out the best solution - a wood block in the
hole or something similar.
In the end my simplest solution - I just left the existing broken
transducer in place and used it to center my drill bit. Drilled right
into it thus removing the old transducer and drilling out the hole for
the new one simultaneously. Not sure how smoothly that would work if
you're doing a paddlewheel but the depth transducer was pretty forgiving
with some electronics encased in plastic.
