broken exost Y ?

[John Olson]

I have a 88C30 and today I broke my exhaust Y where the cooling water enters the exhaust pipe just above the lift muffler. When I removed it I found a clean break right where the water gos in above the Y It looks like this was welded and just broke at the weld. Do you guys think this is cast or steel? Do you think it is somethind that should be welded or replaced? Where would I get a new pipe ? Catalina, Univs dsl, Kabota ???? The next thing is that there is a elbow that threads on the other end of the pipe and then gos into the end of the manifold and some how the threaded end of the elbow just pulled out of the flange on the manifold wich was a real good thing for geting it off but I dont think Its going In that way and It looks like the elbow is rusted on the pipe.I was thinking of mairne texing the elbow to the flange then bolting it on the manifold .Well what do you think .I have a four day weekend comeing up and I would like to fix this but there is agood chance I wont have the parts by friday . Im in the north east and there is only about six weeks befor Im out of the water I hate to loose good boating time . thanks for the help in advace John Olson

Be Careful!

John,When you are dealing with exhaust gases, be careful! CO is a killer. Not as leathal with diesel, but still a killer. I would definitely not put marinetex or any type of epoxy sealer on such a critical joint as the exhaust flange. Engine vibrations will work it loose in a very short time. Maybe for a quick fix you can get the parts welded together, and then go for a proper fix after you haul in a few months. Order a new flange from Westerbeke/Universal, and a new exhaust riser from Catalina. Not a super cheap fix, but do you really want to flood the cabin with diesel exhaust???? Just a thought

Overnight

The parts from Catalina. Not cheap but should be time to get it. I recently had to replace my exhaust riser, Catalina was very helpful. Only one problem, in my case, for an exact fit, they requested I foward the old parts to them. One thing I found from the experience is that this part from the engine guys don't work.Could be different for yours, maybe not.Paul

Have a new

exhaust flange. The exhaust riser is in good shape but it looks like it had a weak weld. It always leaked. I am going to try to have it rewelded. What do you think? Did your part from Catalina fit right?I was thinking about making the whole thing out of schedule 80 steam pipe with 2 22 degree elbows at the top corners and a T with a Y to accept cooling water. What do you think of that so we can sail now and have the part made for the season? John
