How much water can your manual bilge pump pump when you are not aboard?

Do you stay aboard 24/7?

If you do not stay aboard 24/7 don't you think having an electric bilge
pump with automatic float switch might be a smart move?

You keep your boat in a slip, I believe. If you're in a slip then
connect to the shore power outlet. A small ten-amp built-in battery
charger will run a bilge pump indefinitely. Of course, most electric
bilge pumps have limited capacity compared to the horsepower a man with
a bucket can apply but a man with a bucket can't apply any horsepower if
he's not aboard.

Maybe Bobsprit is right about your ineptitude when it comes to boats???

The Boob doesn't know squat. He's never right about anything. I
don't need a electric bilge pump. I don't have shore power (although
the boat was pre wired at the factory) When I leave the boat I close
all thru hulls even if I'm coming back the next day. I have no water
leaks except for a small amount that enters the mast when it rains.
Now tell me why I should fart with an electric bilge pump.
