I just purchased a 1999 Sea Ray 210 DC with a 200 hp Mercury outboard.... and I was wondering if anyone knew how water drains from the mid-ship bilge compartment (where the Batteries and raw water intake thru hull are) to the stern Bilge (where the bilge pump is located. The water does not drain to the back. I have tried to pass a snake from underneath the tank from both ends and am having no luck getting through to a side. Is there a stringer with limber holes under the fuel tank (to support the weight?).
