Solved: it wasn't self-priming
I disconnected the raw water intake from the pump and opened the seacock. As water was flowing in, I stuck the hose back on the pump and re-installed the hose clamp. I started the engine, and got plenty of water out the exhaust almost immediately.
There are signs of wear on the pump, so that is probably why it does not self-prime anymore. I will buy a new pump next year.
