That's easily measured from the engine room or below deck where you wish to install the transducer. The deadrise isn't consistent and varies from the forefoot to the transom, as you move aft it decreases.
Right aft of the fwd engine room bulkhead is a good place and easy too reach, but will require a steep angle fairing block on the outside and inside to have the transducer point straight down. You will also need to get a long transducer. You can easily calibrate the offset from the keel bottom to the transducer position and compensate with the difference to read the actual depth under the keel and not from the transducer location.
