Yes, I did this.
My transducer is mounted to port and off the centre line. Hunter
376 with a Raymarine
log installed by Hunters.
As a consequence it reads differently on port and starboard tacks - so I filed away the registration
pip so that I could angle the xducer off the straight ahead line in the hopes I could make it read equally on both tacks.
This didn't really work either.
However I noticed that it is very insensitive to its actual angle so, if yours is only roughly looking forwards then it will probably be okay.
By roughly I mean +/- 20°.
BTW: I needed to replace my echo sounder xducer. They had put it in with Corning 5200. It was so tenacious and springy that every time I levered the flange 1/2" away from the hull
it just sprang back again. The only way to break the seal was to put the grips on it from the inside and rotate it regardless of the damage
to the threads. It needed a full quarter turn before the sealant
was stretched to breaking point. The thread on the xducer was, by then, indeed truly bu**ered.
