Aren't boats under a certain size supposed to have floatation foam that helps keep them from sinking?  Does that also affect the inclusion of a bilge pump?  I'm no expert on boat's that size but it sure seems like a inspector ought to be.  
Start by contacting Four Winns and ask them about how it's set up.  I've exchanged a number of messages with them this season and they've been VERY helpful.  Send and e-mail to: 
boating@fourwinns.com  You may want/need to include the Hull Identification Number (HIN) of the boat as that may help them determine exactly how it was set up from the factory.
