A close guess would be about 6 cubic feet. Figuring the box is 20x20x45 / 2 because it is more triangular than cube, / 1728 to convert from inches to feet, then round up. It might be as large as 7, but I doubt it. An exact figure is tough(unless you fill it with water or something), as it has complex compound curves.
There are basically only 2 compressors used by any manufacturer. The Secop BD35 and BD50. With a well insulated box, the DB35 is enough, but I would recommend the BD50 in either case.
Are you replacing the whole system, or just the compressor? If just the compressor, the connectors on the compressor will need to match, as there are a few types. If a whole system, there will be lots of differing opinions. Mine is to use the BD50 Compressor, and the largest evaporator that you can fit. I was surprised that the evaporator I wanted to fit, designed for a 14 cf fridge or 4 cf freezer physically didn't fit. So look at what is available and measure carefully.
Insulating the box properly will reduce power usage by about 75% or more unless you live in a cold area. It's big job, I am just finishing it up. It has taken 7 full days of work, and mostly all that is left now is redoing the Formica countertop.

thanks for your information. ordering the frigoboat unit
Keel-cooled K50F with manual speed board.
and trying to sort out which condesner plater to use. How is your set up working? Thanks in advance

I am very happy with it. I got an evaporator That was (IIRC) about 7" x 39". I folded it into a square with one side open a bit, to fit in a 12x12x12 area for the freezer half. The rest is all fridge. The only "issue" is that the fridge gets too cold. Even with 2 inches of closed cell insulation between the freezer and fridge, there is about a 25 degree difference. So if I crank my freezer to below 0F, my fridge freezes too. Once I get back in the tropics, that probably won't be a problem.
As for power usage, it sips power here in SF. Maybe 20Ah per day. I expect 30ish in the tropics. My 12V Dometic Chest used about 100Ah per day for a bit smaller capacity. Insulation is everything. Don't cheat yourself, a small freezer that works better is better than a large one that doesn't.
