I was so happy to receive the new "optional exhaust elbow for my Yanmar 100 hp engine last week.
It is a beautiful casting probably weighing 12 pounds. Unfortunately, when Amel turned the intercooler upside down to allow access to the starter motor and raw water pump it changed the tolerances of the space at the elbow and the optional manifold will not fit.
Back to the old model. I will keep the one I had re welded as a spare.
