Re: looking for past or present owners of 1970 through 73 cal 27s
Jack.. depth finders are not expensive these days, the thing with the transom mount is you'll need to see you close your transom is to the water at low speeds, such as when you're looking to drop the hook somewhere.. If the mount needs to 'hang down' a ways it's vulnerable to damage.
Most transducers nowadays can be mounted inside the hull, and 'shoot through' to get the depth. A variety of techniques work here, including epoxy or wet mounts in a 'box' - they'll avoid drilling another hole..
The other thing is there's good odds that your tranducer is fine, and it may well work with another brand of head. I was able to connect a new Raymarine display unit to a 30 yr old Signet transducer - works great.
I'd go to Ebay or CL and buy an older display unit (ideally the same brand as the transducer if it's identifiable) but even if not, for the $50 it might cost you it'd be worth a try. There must be a cutout where the original instruments were, that might give you an idea of what type it may have been.
