Yes and about 80% of all commercial, older homes, auto AC are using R22.My biggest concern is the sticker says it uses R22 refrigerant, which is being phased out.
We are on a collision course.
I will not engage on the refrigerant phase out, but alert you to this fact.

I just fixed my same 16k BTU unit about 4 months ago. The Tecumseh® rotary compressor was checked by my AC repair service with a High Tech computer gauge, but I had to show him where to connect is Temperature probes on the Sea Water cooler.
My 16K compressor was ID'd by Tecumseh® as built in 1997. If you get the number off the side of your compressor, I can decode it for you.

Bottom line was my Tecumseh® compressor was in great shape. No R22 was needed.
If you look on the top of the Compressor, there are 2 black connections [pict 2]
The smaller is a combination Surface Temperature and Current overload. Mine was bad and I got a wholesale replacement part, per Tecumseh®, and replacement for total installed cost of $150.
The rest of your unit is basically simple. I would use a water side heat exchanger, cleaner like Barnacle Busters to circulate and clean it prior to installation.
I keep mine clean, by periodic [ ≈4 times a year] addition of 1" Chlorine tablets in the intake water strainer.
You got a great find since a new 16K unit is about $2500 brand new uninstalled.
A happy MarineAirrr. owner.

PS: I have all the manuals and even the Tecumseh® detail shop drawings for the compressor. I will share them in a PM. Beer is always welcome bribe.
PSS: Tecumseh® service representative was fantastic with his help.
