Not all setups are the same. I have a sea strainer mounted about the height of the impeller. The hose between the two dips down to to bottom of the bilge so it would constantly be full of water. The short distance between the sea strainer and the intake would be full of air. The short amount of time to draw water into that section should not cause the impeller/housing to actually get totally bone dry to the point of frying the impeller. All "Friday afternoon" theory of course.
Oh, I should mention I fill that section of hose with water when I de-winterize before starting. Because - why not.
