Cloaked- thanks for the thoughts. I put weep holes in the primary stringer at the lowest point, so all water in the hull will drain to this pump location. Very few spots where the water can get trapped - the only places are where the hull isn't flat (build up for skegs, pylon mount...)
I will look into a dripless packing system - you're right, now is the time to replace that if I ever do.
I will be putting a hatch over the bilge in its current location for maintenance and service.
The last pump was under the oil pan of the engine. What a PITA and it wasn't even pumping out the whole bilge.
