there are basically two model pumps, 500gph, and 1000gph.
if you have two A/C units it will be the bigger one.
just call any bayliner dealer since you have to order it from them.
The Motor and the pump as two parts, but it sounds like you lost both.
You looking at $500 to replace.
your insurance will pay, minus your deductible.
the bandit was a boat with A/C i'm guessing.
Lucky they did not flood the boat, after cutting the hoses. They must have closed the sea cock.
on a positive, note, the pump was due for replacement after 13 years.
