Fridge compressor submerged in fresh water- junk?

[Sea Change]

I have a fridge compressor unit which was in storage, disconnected from the evaporator plate. It uses self sealing couplings.
It was next to our watermaker which unfortunately sprang a leak, so it ended up submerged for a few days.
It's come up with crusty, white powder on the radiator fins, but otherwise looks ok.
I'm kind of assuming that it might be junk now. But before I throw it away, what would happen if I wanted to try running it? The refrigerant cannot go anywhere so I don't know if that would cause further damage.
They're flipping expensive things, it was only in use for a couple of years before I disconnected it to take to the new boat. It's a bit of a big lump of ballast to be carting about if it's beyond use.

I would apply power to compressor and see what happens. Presumably you have dried it out. It won,t compress properly but should. confirm if motor and drive circuits are still ok. ol'willl

The self sealing couplings should do just that, seal. I doubt there is anything wrong with it, not sure would not try and run it while it's disconnected.

I know the actual pump is contained inside the pressure vessel, but I think there's a good chance that the electronics outside of that might be corroded.
I don't currently have a functioning evaporator plate to go with it- we managed to crack a pipe during the aborted installation attempt.
If the compressor is dead, then I'll probably buy an Alpicool or similar.

What's the worst that will happen if I try to run it for a few seconds?

If your watermaker sprang a leak, wasn't that on the pressure (salt) side? Seems more likely.

No, it was the product line, a nylon fitting came loose.

The electronics are a standard board available quite cheaply on Ebay and the like. Very basic circuit so unlikley to have been harmed.
Assuming a Secop (formerly danfoss) system, which most are.

Thoroughly dried out before applying power it will likely work OK
