ST800/P120 (Plastic) vs. (Bronze)

Chuck,

The thermister in my ST800/P120 (Bronze) transducer that's connected to a CP370 has failed (currently reading ~ 104 degrees). I do NOT need to replace the thru-hull, only the transducer.

My question, will the transducer from the Plastic (E66071) fit the Bronze (E66072) thru hull? There's a significant cost savings if I go with the Plastic.

Feature suggestion - if they ARE interchangeable, please offer just the transducer at a correspondingly lower cost.

Thanks in advance,

Joe
