One leak that I discovered was starting at the aluminum angle at the back of the pilot house side window on the port side. The pilot house gutter ends at the angle and it was dumping in rainwater because there was no caulking at the top. I removed the angle and found that the fiberglass molding is open behind it. You don't have to take off the angle but make sure it is sealed at the top and down the sides. That only stopped the flood into the foot of the guest bed.

I was also able to check the hoses and drains during a rain and found that there is a drip running down the 3 inch vent hose coming off the bottom of the engine vent and dripping just near the thruhull for the deck drain on the monkey fur. I don't see how to remove that engine vent to see how to seal it up. It would be nice to just seal and cover it up with a nice panel since the 4788's don't even have a vent there.

Plus 1. AND as previous poster stated- check the scupper there as they do deteriorate or clog and overflow into bottom of air intake vent (has a gap) and will flow into the stateroom. It's usually always something pretty simple- of course that's what I said when the Space Shuttle blew up in 86 too.

We have the same problem on our 4588. It is dripping out at the back outer wall of the bed and gets puddled up along the back bulkhead wall. I ihave cut a large access hole in the back wall above the shelf ledge and have looked in there while it is raining and cannot see the leak. I have also removed the bookrack in the pilot house but still nothing. I removed the deck drain outside the helm door and rebed it. I guess I will try recaulking the door track and the air intake vent. Will post if I have any success.:worth

"The aft bed room continues to leak during a rain. Water appears under the shelf at the head of the bed and travels along the underside of the shelf to the rear of the shelf where it drips or runs down"

A 45 Bayliner with a leak at the 'head' of the bed along the shelf near the porthole.

This area slopes from bow to stern and the leak is originating at the very head (bow end) of the mid stateroom.

Also says that it leaks during rainfall which is why I have not mentioned the possibility of an A/C condensate overflow.

I assume you are talking about the midship stateroom. A good place to start would be the track on the pilot house door. Check the screws holding the track in place. Also, mentioned earlier....if it is the bow stateroom...if water gets into the locker box on the bow, water will leak through the weep hole between the laminant into the locker on the port side. Not sure if it would travel to midship stateroom though.

Had simular problem with water leaking into the saloon of our 4788 and found the flybridge scupper drains are plumbed to drain down in the wall to near waterline. When these conections or hoses become a leak problem its a mess. A "fix" I went for was simply to change the drain to go thru to outside the flybridge wall as shown in pic. (Sorry about that I guess I'm too handicapped to insert an immage.) But you get the idea and it really works well and will never leak into the boat again.

You might want to check the drains from the fly bridge. On our 4588 the forward port drain hose connection was broken. It is found by removing the pilot house magazine rack. After removing that rack try wetting down the fly bridge and see if you see any water intrusion. Best wishes!

We had this leak on our 45 and finally traced it to the forward port hatch on the bow. Spraying water on it did nothing. When I put a hose in the locker and filled it with water, the water showed up where you are describing.

the next place to look: open up cabinet door at foot of bed... look up to where the scupper drain from the deck drain is... grab the hose, wiggle/move... they used a regular 'sink' drain made from metal that will corrode...hose clamp may feel tight, but drain is simply rotted away. if you add water on deck into this drain scupper on port side of pilothouse and you see water coming in..... this is it!

good luck. Ken

"I have sprayed water on the side windows, front windows, front storage hatch and the dryer vent for extended time with no sign of a leak. Does anyone have an idea where to check next? Removing the magazine rack in the pilot house allows inspection but no moisture is present."

Rail stantions, mid cleat , base track for sliding pilothouse door, porthole.

Hope this helps

I have a friend with a 45 with a rain leak that he can't find.. here is his question... anyone have an idea here?

"On my Bayliner Pilot house 1990 4588 built in South Carolina;

The aft bed room continues to leak during a rain. Water appears under the shelf at the head of the bed and travels along the underside of the shelf to the rear of the shelf where it drips or runs down.
