No, I have seen perfectly suitable stern quarter outlets, bow and even side discharges with a center-line siphon break and a shut off seacock... I do prefer the stern though as do many builders who try and do it right..
Side discharges are my least favorite and I would personally avoid them at all costs on a sailboat. The proper installation of the siphon break gets difficult and can leave exposed hose visible in the cabin, to do a "safe" install for a side discharge..
Bilge pumps to me are not an "after thought" they can be a safety item and one that should be taken seriously. Having had a thru-hull fitting snap, another story for another day, I do take bilge pumps and proper installation techniques seriously.
My main objection is using a check valve to keep your vessel afloat. But I am not alone on this and the ABYC concurs.. My only beef is the use of check valves on a primary bilge pump when that pump is also a centrifugal/Rule type.
I have less issues with them on rotary vane or diaphragm pumps because they CAN open them where the centrifugal often won't...
