Not such a worry, as it turns out.
I neglected to refill my old engine with oil one spring launch. The un-suck-able quart left in the engine was sufficient to let the electronic fuel pump run the boat out of the launch bay, around to the slip, etc. Only when I checked the dipstick later in the day did I realize my error.
I don't know what the pressure threshold is on those oil pressure "safety" switches is, but it ain't much!
