The most common areas for leaks on the older Prowlers were the scuppers, keel line from dragging and, depending on year of boat, the rudder attachment point. I would start with the scuppers. Often you can see the leak point upon a simple visual inspection. If not Duct tape closed the bottom of the scuppers so they are basically a cup. Fill them with water, soapy water is better. Make sure all hatches are closed then do the air pressure test, as described above, through the drain hole. If you do not have a compressor a battery operated pump for air mattresses works great and usually has a fitting that will wedge right into the drain hole.
