The pump in Hopcar's link will do just fine with a 16k.

Also, pumps are generally fix-able, depending on model and what might be wrong with it.

Most of the boats I have seen don't have their overboard discharge 5' off the waterline

This is true, but you will see applications such as my boat, where the waste water discharge includes the gallery sink , ACs units, condensate drains, and other water source discharges, exit through one or two above water through hulls. Essentially, I have two 2" through hulls that handle bilge pumps, washing machine, galley sink, 2 AC units, the shower sump pump, and 2 deck drains. Two of my AC units discharge into common drain pipes 3 to 4' above sea level.

Gallons Per Hour and Gallons Per Minute are ways that you measure water flow rate through the pump.
Example: 10 GPM times 60 minutes equals 600 GPH.
If 600 GPH is good enough for the aft cabin 16000 BTU AC unit , it should be good enough for the forward 16000 BTU AC unit, assuming the plumbing is reasonably the same.

Yes I agree, and that is part of the fun of it for me. However, it is time to let this one go. Just not enough hours in the day for this one.
