2000 SSi 235 through hull transducer

[donaldmswanson]

I have a 2000 SSi 235 that I purchased new 23 years ago. I am having problem with the hummingbird HDR 650 depth gauge not working. I believe it is through the hull. Hummingbird HD650 transducer looks different today. Anyone have experience replacing this? Correct interchange?

I just quit using mine and installed a Lowrance fish finder with the transducer on the stern.
