Default Water pump losing prime

It seems to me that this thing should pump even if it does lose prime
because you would expect it to lose prime as the boat heels and waves
pass under. Any thoughts?

Possible causes, more or less in order of likleyhood:

1. Raw water impeller is tired and needs to be replaced.

2. Raw water intake through hull fitting is fouled. I once sucked
in a jelly fish. Barnacle growth is common.
