I set the Zodiac 310s up last night to mount my fish/depth finder that I got for Christmas. My plan was to mount the transducer towards the bottom edge of the transom. However, I noticed that the fabric for the bottom of the boat wraps up and attaches to the transom (about 3 inches or so up). Right where I need to mount. Do you think it'd be okay to mount the transducer on top of the fabric, through the transom and then put silicone around it to prevent any leaking at the edges? Thanks for any advice on this.
