Muffler Problem

[Jack Bego]

I finally took some time off to go sailing and get better acquainted with my recently purchased CD 28. After about five minutes of motoring , I thought the exhaust sounded a little strange and then the smoke and fumes started streaming from the cabin below, the bilge pump started shortly thereafter. It turned out that the exhaust pipe from the manifold had seperated from the top of the muffler almost all of the way around. Does anyone have any experience with alternate methods of reattachment, ie; Marinetex, instead of welding. I would like to repair it in place to assure proper alignment of the exhaust pipe with the manifold.

Jack, I had the same thing happen to me just last year on my CD26D.

On the Westerbeke the exhaust pipe is 2" water pipe. I replaced it from the manifold to the muffler. I bought the pipe in HOME DEPOT. Stock lengths worked. If not they will cut them for you.
ALSO the Muffler bracket had come loose from the back of the transmission. I don't know if one caused the other to happen.

I'm glad the job is over.

I had a similar failure. Ended up replacing everything from the rear manifold plate back to the muffler. Quite a nasty and expensive proposition. The straight pipe sheared off at the rear manifold and water got back into the engine. Ended up doing a complete engine overhaul out of the deal. The westerbeke dealer did tell me that that piece of "water pipe" should not be galvanized pipe since when the galvanizing gets hot it gives off toxic fumes. I replaced mine with "black iron" pipe, the kind used for building sprinkler systems. My pipe is about 10" long due to the need to spin the injector elbo and clear the engine heat exchanger. Thats a lot of galvanize to vaporize. I have never heard the toxic fumes theory from anyother source.

I suggest you replace everything in the exhaust system that looks suspicious. From my experience a bad exhaust system can kill a good engine..

Good luck... Boyd

If it's the riser you are having trouble with replace it with BLACK IRON industrial pipe fittings. Works the best and is long lasting. Stainless is a poor choice because any welds will fail. Bronze is good but not like black iron.
