Mount the tranducer nearer the engine in the wood insert in the transom with 1 1/2" #12 SS sheet metal screws and use an adhesive like 5200 as a bedding compound. (If you ever need to remove this you'll need a heat gun and a lot of patience. You will probably destroy the transducer removing it.) Be sure to counter sink the gel coat around the screw holes before you start the screws to avoid cracking the gel coat with the act of inserting the screws. Choose the port or starboard side based on whether your boat lists to port or starboard when under way. (Choose the side that runs lower.) All things being equal as to listing, the transducer mounting instructions usually suggest which side of the prop to be on based on prop effects on the transducer performance.Yes, I know that the common transducer location is further outboard than this will allow. On my old Montauk, this location worked fine with a smaller, older transducer on an Apelco sounder. You might try mounting the transducer on a board you can mount to the boat with c clamps over the transom first to see if this spot will work for you. (Obviously, you won't use adhesive for this test!)
I'd love to hear how the unit works once you solve this problem.
