My R29CB was new in June with 116 fresh water hours on it. I've only owned the boat for 2 days.. Today, I noticed that the chain locker was not draining. I couldn't clear it from above or below. It was a VERY solid block. What is the reason for this and how do I clear it? Would organic matter do it that quick? Does the outlet shroud contain anything that can fail? Thanks.
 
The drain hose was probably kinked when boat was built. I heard of this twice before with R29. I would talk to factory.

I had this problem when I first bought my boat, too. It was a clog in the drain. I was able to clear it by using a high-pressure hose fitting (see photo for example) from the inside of the locker. It blew out the whole clog, which was mostly caused by small, decaying pine needles.

If I may share a quick story of boaters helping boaters, I discovered the clog while I was at DuSable Harbor Marina in Chicago, just before starting my Great Loop trip. Another boater saw me struggling with it and offered his high-pressure hose fitting. It immediately did the trick. When I tried to return the fitting, he told me to keep it.

Wow! That's awesome. I did try to blow it out with a hose but not with the fitting. All I managed to do was fill it up more! 😀
 
I'll let you know how it goes. The boat is so new that I'm not quite convinced it is just a blockage. Mastrcraft said it has been kinked from the factory before...The boat still has the one year stem to stern warranty so it should be ok one way or the other. BTW, when warranty work is needed, do they come to you or you take the boat to them or what? Thanks.
 
Well, here's an update. As was mentioned hereby Mastercraft, the factory suggested that I check for a kinked drain hose. I got the feeling that this is more common than they would like. The access panel is about 12" behind the hinged headboard in the V berth. It is secured very snugly with square head screws (use a power driver if you have one, I didn't have mine with me!) And this is what I found: Behold. I haven't' figure out my fix yet except to somehow loosen the clamps and pull the hose from the fitting and go from there. Obviously, this is a warranty issue, It came from the factory like this in June, but luckily I'm a plumber/pipefitter by trade so I'll tackle it myself. I'll post the fix when it happens. 20251113_134105 (1).jpg20251113_133256 (2).jpg
