OK, this is a bit embarrassing. But here are the results. The original problem was the impeller breaking. In diagnosing that we opened the strainer and then screwed the lid back down. Reused this gasket. It leaked air but we didn't know that. The top is above the water line. We thought the problem caused the impeller to break, not that it was the problem since on restart we couldn't get water.
Did all the tests and finally realized that more pressure less water. Thought maybe air in the pump. So the last thing we did yesterday was go to Canadian Tire and get some gasket material. We put on a new gasket and tested the engine. No water. Ok, here is the embarrassing bit. We closed the thru hull when we did the gasket and forgot to open it when we did the test. By this time we were done, turned the engine off and went home. Today when we were starting I noticed the thru hull wasn't opened. Opened it and started the engine and the problem disappeared. So it was one problem that morphed into another followed ultimately by an error. Thanks to all for their comments.
