Oil leaking - filter issue?

I was idling out of my channel yesterday and all of a sudden the oil pressure alarm goes off. We killed the engine immediately and luckily we were very close to a dock, where I tied up the boat for the evening (it was late and the bugs were out). This morning we brought a bunch of oil over and filled it back up. I fired up the engine and the oil pressure was back at 40psi, so I idled the boat back towards my dock. By the time I got there (less than a mile) the oil alarm went off again. I checked the rear bilge and it was full of oil. It must be leaking from somewhere - could this be due to a clogged filter? Boat is only 9-10 months old - 2007 MC X45 with a Crusader 375hp 6.0 engine.
