[Lured Away]

Can anyone explain the plumbing route on the grey water tank in a 37' Open? Looks like all the sinks, shower, etc, drain to the tank which is in the forward part of the engine compartment, instead of directly overboard, and then the gray water tank drains to the holding tank? Any way to route gray water directly overboard? Seems like would need to pump out much more often. I only see one pumpout.

The breaker panel has pop out breakers for gray water pump and gray water pump #2 that look factory. I can find one pump that is on top of the gray water tank but where is the second one? Thought might be shower sump but is another breaker for that.

Thanks
