Exhaust elbow D.I.Y. project...
Replaced my port side through the bulkhead S.S. exhaust elbow with a filament wound fiberglass elbow. The last time I took out the S.S. elbow to be welded (bad idea) I installed Nut Serts in the mounting holes, so I would not have to deal with washers and nuts. Worked out well, as I was able to use screws to jack out the elbow from the 3 1/2" exhaust hose.
