Ocean Pro deck problem

[Redgull]

I've recently bought a neglected Humber Ocean Pro 7.5 with Volvo inboard and sterndrive, 2003 vintage, and would like some advice from other Ocean Pro owners. I've removed the engine box to clean out the bilge and uncovered inspection hatches for access to the engine mount fixings either side of the engine and found both these chambers filled with water. Should these chambers be sealed watertight with a hatch cover clamp or should they drain into the bilge? Should the bow hatch drain into the bilge through a pipe or just through the open cavity below the deck. Any advice would be appreciated as I'd like to keep her in good order.

We've an outboard, so no idea re hatches.

The bow locker has a bung that drains through to the bilge at the back, that has a bung itself. Not sure if that's through a pipe or the cavity, but I think the cavity.

Ours is about a 2010/2011 boat I think.

Thanks for your comments. I'll try and get my hands on some floorplan drawings. I don't want to cruise around with any unwanted ballast below the floor maybe also causing long-term rot damage.
