Transducer

Yeah, the make/model of the boat aren't really relevant. It just depends on the equipment. You might not even know for sure that what is installed is original equipment.
To be clear, you are talking about just a depth transducer, right? Not a combined transducer?

What Greg said. Actually, knowing the brand, and the hertz/cycles per second of the pulse are the key specs if it's just depth. When I replaced mine the transducer was fine, I just had to find the electronic gauge that delivered the pulse at the right frequency (hertz/cps) that was on the inboard side of the transducer. You may be able to find the frequency on the electronic gauge, or on an internet lookup of the original. If you are replacing the transducer, you also need to match the mounting hole through the hull.
The transducer I need is for a DataMarine knot meter. I'm fairly certain it is original to the boat.
Definitely an AirMar unit. Here are the part numbers for what I got for my boat several years ago:
DataMarine CS100
PN 33-415 - Thru-hull spares kit for S650, ST650: paddlewheel and shaft, 4 o-rings, 1 valve sleeve
PN 20-602 - blanking plug
Got 'em from Gemeco 800-543-6326
I have no idea about availability and cost. So, this isn't advice - just something to think about. It might be less expensive to get an all-new unit that includes the transducer. Almost certainly could use existing wiring. Would just need to get an instrument display that fits well in your existing slot.
Again you might just find the transducer for a good price and do a simple swap. But, if not, replacing both ends should be almost as simple, if the display fits.

You can probably find the right transducer for your boat, but the Data Marine display is the weak link. They made great units, but are going on 45 years old. That is like 200 years old for a complex marine electronic device. I did what Foswick suggested and replaced the Data Marine units along with the transducer after the display became so faint that I couldn't read it.

Welcome Sheila to the SBO Forum.
@Joe provides some solid sailing experience. The paddle wheel, speed through the water, and equipment require a lot of maintenance to keep functioning. The information it provides can be low in value in the scheme of things.
With the advent of GPS and tidal-current data from a browser app like DeepZoom.com, you can receive all the data used to determine your speed through the water and the navigational awareness of your progress to a destination with no paddlewheel maintenance.
The bonus is connecting the GPS to your plotter and using it with other data systems.
Rather than trying to make the original electronic hardware function, it may be less expensive to identify the functions you need and desire, then look for current hardware that gives you the resources you want.
