      Comments about Raymarine i40 Depth Instrument:

      Did not want to bore a hole in the hull so purchased the thru hull transducer model. Went to u tube and watched what others had done, called Catalina and asked if there was wood etc. in hull, nope!
      Accessed interior hull, chose my spot and did some hand sanding to smooth puck + size area. Cut bottom off small yogurt container, added silicone to lip of container and pressed it over my spot. I mixed fiberglass resin carefully to avoid bubbles and poured it into my "cup" and left it x 24 hours. Removed cup and had a beautiful little,no mess, almost level mounting puck. Sanded and Mounted transducer w/ very thin layer of slow dry PLASTIC epoxy to puck and transducer, weighted and left alone x 24 hrs. Held my breath and powered it up on launch. Beep! It worked, adjusted settings and enjoyed a year of sailing knowing my clearance. Note, it is in the directions but not stressed, be sure to install a fuse in the power circuit.
