Ok now I feel real stupid. I did a pressure test on the radiator with a rented tester, and it holds pressure just fine. I then tested the cap and it didn't hold more than about 8 lbs. Amazingly enough, a new cap tested and held all the way up to 16 lbs. The real test will be today in the 90 degree heat towing the boat uphill. I expect it'll pass!
