I'm trying to track down a small water leak. The pic below is from the lower compartment in my galley looking aft. That limber hole is leaking water. The water is fresh (my boat is in brackish water).

At first I thought it was rain water, so I check around the windows and caulked a few areas. I also shut off the water supply and depressurized the system, vacuumed all the water up.

I let the boat sit a couple of days and we had a good rainstorm, and no water. Yesterday I was at the boat and applied shore water, and a few hours later the water appeared. So I have isolated it down to a small leak somewhere in my fresh water supply.

So here's the deal. That area is inaccessible. With the exception of the limber hole there is absolutely no access to that void area. Right now it looks like I will have to take a jigsaw and cut an access to the top, and even with that it's a tight spot (next to the AC unit)

I checked my sink above and checked the connections, no wetness, no signs of water. I don't know what's in this void area, but I do know I have water coming from there.

Any ideas?

I flipped them to buy some time before I found replacements.

Got my replacement rollers. Now the question is, how does one install these? I took the door off and looked at the bottom. The frame looks like [ ] and the roller assembly fits inside. But how do you get the old one out and the new one in?

Not much help, but that's not a factory hole. A previous owner created it. They must have figured out there was water in there.

That's one area of the boat I don't know anything about. Since it's closed on all accessible sides the only theory I have is that it's open on the hidden hull side and rainwater from a deck fitting or hull to deck joint is making it's way in there. Or possibly from the master head plumbing (that's the only plumbing on that side of the boat that isn't visible). You can check the master head shower plumbing by removing the fridge. There is a big hole in there giving access to that plumbing.

Since you now have access, can you use a scope or get the lens end of your phone in there and snap some pictures?

It's not from the master head, I know that for sure. And I know it's not rain water, the only time I get water there is when I pressurize the water system. I do see the water lines running along the top of the compartment with the raw water line for the AC, but no sign of a leak there.

I figure I would get a dental cam and snap some pics inside.

How did you rule out the fittings on the back of the master shower valve? If they leak the water would run aft along the inside of the hull. Not sure where it would end up. But there is no access for it to get to the cabin bilge.

If I remember, the side rails need to come out before removing the bottom rail......you will find some stubborn screws. If you have access to a hammer screw extractor it will be less stressful.
 
After cruising around for a couple of hours on Saturday, we were headed in and decided to stop by the fuel dock. On approaching the dock, I pulled the engines into neutral, only to find that the starboard engine continued to stay in drive. Given the number of boats at the fuel dock, this was a very unwelcome surprise! I shifted the levers to reverse to stop my forward momentum, but the shift into reverse immediately stalled-out the starboard engine. The forward momentum of the boat stopped stopped, but my angle of approach to the fuel dock was far less than optimal. After a few quick reactions, some key nautical terms and a lot of luck, I managed to make the fuel dock without harming any boats.

I waited until the dock immediately in front of me was clear after fueling. Sure enough, after restarting the engines, the starboard engine was in gear as soon as the engine started (in neutral). Once in open water, I tried again to place the engines in reverse and the starboard engine immediately stalled. I never had a more difficult time backing a boat into the slip.

I can only assume this is a transmission issue. Anyone have other ideas or similar experiences?

A fellow 400DB owner had this happen to him recently. The transmission oil cooler failed and all the transmission oil got sucked out. The clutch plates all fused together. He had to replace the transmission. Not sure if your engines but his was a ZF 280 A1 on a Cummins Diesel engine. He and I were able to remove the transmission and install the new one with the boat in the water, just the two of us. It was pretty darn heavy, though.

Check your transmission fluid level.

Sorry, misunderstood you. Yes, I’ve had the fridge out. No leaks from shower fittings.

On boat now, removed master head. I found a leaking line that looks like it goes forward, so I’m assuming that’s the anchor wash down line.

How do you cap off these lines?
 
You can cap it off, but I would encourage you to solve the problem. The wash down for the Anchor is valuable when you have one.

Actually I find it fairly useless.

Anyway, I went to WM and bought a PEX valve, installed it on the line and turned it off, so no more leak.

My starboard deflector shield is heavily crazed. Can't really see through it. All the other panels are still nice and clear. Anyone know if it's even possible to replace a panel?

Plexiglass can be polished out. It's a long process and tedious, but would be worth a shot. Since it's heavily crazed you really have nothing to loose in attempting a polish.

Aviation supply carries plexiglass polish kits.

They do come apart but you really don't want to do that if you can avoid it. I had to completely reassemble my deflector after moving the boat. It's not fun.

"They" say that plagiarism is the highest form of flattery, so consider yourself well-and-truly flattered... I did the same yesterday, even replicating your helpful colour-coding... fortunately very little wind... even so, I was nervous about getting overspray on my boat (but, even more so, on our super-yacht neighbor!), so used an old snack box to act as a mobile spray booth... fortunately I have a very understanding dockmaster, as the chain will need to stay on the dock for 48 hours to dry!... thanks so much for this original post... in the past I used a stopwatch to measure the chain drop... now my son has a more accurate measuring stick... with appreciation, Simon
That's awesome! I'm really glad that I did it. I took my "code" and had a plastic plaque made by a local trophy shop for about $15. It's stuck with double stick tape on my dash next to the windlass switch.

I just ran into this about 2 weeks ago... Soaked everything in my under galley storage. There is a condensate pan under your AC unit with a drain that runs to your engine room forward bilge. If that drain is clogged, then your catch pan is likely filled up and overflowing running into your galley bilge/storage. Pull the stairs out, and it will be very clear if this is the case. Run a drain snake down the drain tube, and you should be good to go. While in there, pull the filter screen out of the side of your a/c unit, and hose it out too.
