Tried mounting my depth gauge transducer inside the hull of my '85 C-25, which worked for a few months before delaminating & losing its sensitivity. With no plans in the near future to pull the boat out of the water, my other option is to mount the transducer externally, off the transom. I'm considering rigging a stainless steel "boom", mounted to the pushpit that's long-enough to get place the transducer clear of surface turbulence. It'll also have to be clear of the rudder sweep and opposite where the outboard is mounted. Have any of you done or considered this "mod"? Thanks!

Hi Arnie... You posted this in the Capri 25 forum--I suggest copying and posting it in the Catalina 25 forum.

It worked for me. I put an externally mounted depth sounder on my transom, used a piece of PVC 1 by 2 and screwed to transom on starboard side between engine and rudder. Engine wash did not affect readings.
