I wouldn't put the through-hull for the bilge pumps below the water line. That makes it very difficult for the pump to evacuate the water... since it has to fight the pressure of the water on the output lines... Generally, the output for the bilge pumps is above the waterline.
I would mount a small "maintenance" bilge pump down in the bilge as low as possible, with a relatively small capacity and a relatively small diameter hose. This minimizes the return water that comes down the hose when the pump shuts off. Then mount a larger, high-capacity pump about the same level, but with its switch a bit higher than the one for the small maintenance pump. That way, this larger pump will empty the bilge if the small pump gets overwhelmed, but will stay off otherwise.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
