I would be inclined to stay with the 20 degree dead rise version if you are drilling a hole. Airmar does make a 20 degree P19, you could just splice it into the Hawkeye

If you are not worried about accuracy in deep water you could just glue the transom mount in the bilge and call it done. The signal goes through fiberglass hulls so no need to drill a hole if you don’t need temperature. Hawkeye has a video on gluing the IN-Hull/transom mount model in.

Do you think the glue in will go through our hull? It said no cored hull and only full fiberglass -- ?
