(I posted this question in the 310 sectiion, as well)

Can someone give me some insight on how the bulkheads on either side of the engine compartment are constructed? Specificallly the port side. I have the engine exhaust system removed including the shelf which the muffler is attached to. When it is raining, I am getting a trickle of brown water out of the right side screw hole which the shelf bracket is attached to. (I have not actually seen it drip, only see the streak and the hole is wet when returning after it has been raining for a while) The left side screw, approximately 5 inches to the back is completely dry. I have tapped on the bulk head and there is no sign of softness, and I have pushed a small allen wrench in which does not penetrate and does not indicate any softness in the hole. This screw is just about in alignment with the water heater and holding tank. The boat is shrink wrapped currently, and there are very few leaks in the wrap and the cockpit area is dry.

If I knew how the bulkhead was constructed, and if there were any ways to see in, I may be able to track down the leak. I have watched carefully the side of the hull above the holding tank and water heater and can't see any water leaking down.

If anyone has any ideas, that would be great!

Thanks!
