Does anyone have any info regarding the MD11C Exhaust manifold.
I purchased a new manifold but it is different than the orginial one. The orginial one has a part # 833357, the new one is part #829930
The newer one has a redesigned water flow to the thermastat. with a water port located sort of offset from the "T" port on the bottom of the part. Any help? Thanks

I recently had the same problem and could locate an exact match for my MD11C in my Pearson 323. I ended up making up a new one from a bronze T and some plumbing parts purchased at West Marine. The only tricky part was to drill and tap the bronze plug inserted into one side of the T to accept the water input. It''s been in the boat now for about 5 years with out a problem.
