You can buy just the thru hull with out the transducer, I got one from Defender and you could try the site here. It was an Tack Tick part, made by Airmar ABYC H-27 ~25.00
The od 2.0" 50.8mm, id 1.625" 41.26mm. Bore it out to fit you new transducer, bed it to the hull then bed the new transducer transducer in ti . You will probally have to shorten the adaptor a bit.
