This is a Mega DI transducer on a new 24v 80lb Terrova.

Pretty big transducer and with the ruler in the pic, it may help in your research.

Transducer is about 71/4" long but is built in to motor.
The transom mount transducer may be slightly shorter with mounting bracket.

The suggestion of mounting the transducer on the fin may work with your motor.

Good Luck
