Tinker the Aerotec air floors are impossible to find on their own so unless you find one for peanuts with damaged tubes but an OK air floor then I don't see how you'd get it up and running. It's an early one and I reckon I can see the transom seam has some glue/mastic repairs.
Engine looks clean.....the trailer though..... wouldn't want to tow it 100 yards. Looks like they have used carpet to protect the SIB floor from damage...
