Yes, the Jabsco pump is a bit slow, but personally I like having the bilge dry....one of the advantages of an encapsulated keel is that it is possible! And getting the bilge dry forced me to find a couple of FW leaks - one in each water tank (the inspection hatches were not screwed tight enough) and about 4 in the HP water system. But since then I have had a dustbowl in the bottom of the boat :-). So although letting the water drain into the bilge is an option, you may want to wait a bit, to be sure that is what you want to do!
But I am happy that you found what you are looking for. Exploring all the nooks and crannies is part of the fun of a new boat - and the P323 has quite a few hidey-holes. For example, you may want to check under the plastic bin under the chart-table seat - a pain to get out - I discovered that was where the PO kept his engine parts!!
Have fun!!
