While To be proper, the refrigerant should be recovered. However the few oz of refrigerant is not that much in the big skeem of things and will cost an arm full to recover.
If it were me without a lot of money
and I had a small system without a gauge port. I would buy a ice maker saddle valve and some 1/8" tubing. Attach the valve to the suction side of the compressor ,with the valve in the open (unscrewed) position. Attached tubing to valve and route
to the outside, then close the valve which will put a small hole in the copper tube. Open the valve to discharge the gas to outside the boat. Not at all legal
BTW, but safe for the folks on the boat. Then just cut and dispose of the old unit.
Of course if the unit is not cooling
it might be out of refrigerant anyway.
Anyway, that's what I would do, if I had a small 12V system.
