Re: Yanmar 2GM20F mixing elbow Pearson 31-2

Update: We ended up re-using the joint (I couldn't unscrew it anyway) and the clogged elbow, after chiseling away the blockage. We used non-permanent permatex (I think that is the blue as opposed to the red) when we screwed the joint back into the exhaust elbow. We also replaced the gasket where the exhaust elbow bolts to the cooler. It was not necessary to use any treatment on the gasket.

She's been good so far this season. Starts like a charm.

Oh yeah, when I was torquing the bolts holding the elbow to the block, they felt like they were stretching too much, so I stopped rather than break one of them and order new bolts. It may have been my imagination, but better safe than sorry.
