 I'm about to install a new fridge unit (old long gone) into the cooler compartment. I opted for the isotherm 2301 air cooled with the rectangle box evaporator . I also bought the AC/DC converter to run either power source.

1st question: The converter changes AC power to 24V DC. The DC electrical system of the boat is 12V . Do I have an issue with 24V?  (that's two 12V batteries in series.)

2nd question: Can I put the compressor in the engine compartment RH side on the shelf right above/ behind the cooler box? Most convenient place to utilize all the old exiting holes in the cooler box.

Or, does it have to go in the cabin area for better ventillation (galley). There are two spots to place the compressor: either the bottom shelf in the extreme left side galley cabinet or under the stove in the pots and pan compartment. I could router slots in the door face for air. This spot might be a challenge to route the copper tubing up and around and wiring. I don't really like it. But its spacious.

Under the sink is too far and difficult to wire to and I don't want to hamper access to the thru hull.

Where have other owners put their compressor? Any suggestions or advise ?

I just put an Isotherm asu sp holding plate in. I have a de 32. I mounted mine up under the sink on the bulk head. Not sure what compressor your unit has. But the danfoss db50 is dead silent. I mounted  it. On 1/8 piece of rubber pad.

The box is on that side of the galley in a 32. The 38 is on the opposite side aft. Running electrical and copper is too far away and too many u turns and bends to snake it around.

 

I see in past posts a couple of people put the compressor in the engine compartment behind the cooler on the shelf. The perfect location. They claim no problems. I was advised by the manufacturer NOT to put it in the engine compartment. Does anyone have any knowledge this is in fact a bad idea?

my unit is the Isotherm 2301 Compact Classic.

On our DE 38 it is in the engine compartment about 12 inches from the fridge compartment. Worked fine for many many years. I'm pretty sure that the extra heat in there didn't help it keep the fridge cold though. I think a water cooled unit would be the ideal for mounting the compressor in the engine compartment. I have heard of people using the sink drain with a special system to do this and I have heard of commercial units made to be water cooled.
