I finally found a major leak the main salon on our 10 meter flybridge aft/cabin. There is a louvered vent on the starboard side that had nothing behind it except a direct access into the shelving unit inside. Does anyone know what was supposed to be on the back of the vent to prevent the leak? Was it a vent to the engine room or just for decoration? Thanks for any help.

Wes,
On my 10 Meter express cruiser, there are two louvered vents, one per side just forward of the radar arch.
These are cleverly placed to allow air to flow behind the cockpit liner to the engine room.
Combined with the 2 on each side behind that stainless grill these vents allow air into the engine room. (the port side stainless grill has one for blower exhaust when the blower os ON. I believe these all become intakes when the engines are running with the blower turned off)
In the cockpit of the express, there is a removable panel with insuation under it that runs below the side window glass from just aft of the helm to the back of the radar arch.
The wood planks to which this insulation is attached, beneath and to the side on mine were damaged a bit, however that damage was caused by the original owners installation of an outrigger setup, with the 1.5" open fitting allowing rain water to flow directly onto this wood.
To remedy this I installed temporary plugs in the outrigger bases when we're not deploying the outriggers (which is almost always) and coated the wooden planks with fiberglass resin to eliminate any future problems.
I don't know how this relates to your flybridge/aft cabin model but it must be similar and the vents are in fact functional and necessary.

Thanks RWS,
I haven't found the way to get the main salon bulkhead walls off yet, but I'm going to try that today. I can't see ant covers in the back of the louvered (just forward of the radar arch) vents that lead to the engine room but that's what I think might be the answer. Working on an older boat (1983) is always an adventure for inquiring minds. LOL

On the express cruiser you will find the inboard fasteners are behind that thick silver insulation on the inboard side.
On the outboard side there are several horizontal screws located level with the insulation, but hidden just behind the edge which is covering the screw head. The starboard panel looks like this, with the lip going over the cockpit "liner"

Thanks RWS. Yesterday I removed the louvered vent and felt around as much as I could. All I found was solid plywood with wires running through. The wasn't any loose fitting or holes for vent tubing to go to the engine room. Either Trojan thought the venting wasn't necessary or someone modified it later. I'm goint to try to get into the bulkhead within the next week or so. I really appreciate your help.

Then what prevents the rain and spray from getting to the inside of the main salon? I have had pools of water in the starboard shelving unit after a rain storm. After I blocked the vent the other day we had a tremendous down pour and everyuthing was dry. I'm going to go to the boat tomorrow and I'll shoot some pictures of what I mean. My regular e-mail address is DiLuna @ aol.com, (without the spaces) and I'll send some if you let me know your address.

The vents are directional, meaning they have a correct way of being installed.
If they are upside down, they will allow water to get in.
Take one off and examine it, you'll instantly see what I'm talking about.
Whenm you re-install it try some of that removable soft caulk between the vent and the fiberglass to keep anything else out.

There isn't any fiberglass behind the vent, just plywood. It is like a plywood box behind the vent. The louvers are pointing forward. I would assume that would be correct if you wanted air flow to enter while under way. The only thing I could see when I removed the vent was, what looked like a plywood horizontal box with wires running along the bottom of the box. I'm really going to have to get the whole wall apart to see what has been done in there.
