I had one of those several years ago.
I had the tunnel hull model.

The one I had was setup for an insert pump, E type.
Those pumps are quite limited in performance. You stated that the boat you're looking at had a setback pump. An insert pump looks like a setback but the intake is molded into the hull.
Look under the dash at where the bulkheads connect to the hull.
When I got the boat the bulkheads were all loose and it required many hours of fiberglass work to glass it back together.
