Is there a way to test the transducer to see if it is 200khz compatible for
the new Elite 5?

It is quite a simple procedure actually that can be discovered in one of a few
different means.

1st - Consult the product information for the required information. or
2nd - Call a local supplier/authorized service provider. Many Marinas and
boating accessory sales locations will be happy to provide you with some
examples.
3rd - Call the manufacturer.

Can I simply splice it myself or is there a reason why I
shouldn't. I have spliced coax many times.

Many people can splice coax. Very few will do it right or not at all when
inadvisable. being able to pass a signal is no indication that the splice was
done properly. Given your past posts covering a wide variety of subjects and
technologies, hardly any having to do with the actual purpose of this group, my
advice is to contact the manufacturer for advice and the proper parts for your
ideal installation.
