Re: How to destroy a diesel in one easy step...
Capt Len - Clogged with a carbon build up of salt water (Yanmar Engine is Salt-Water Cooled) and carbon. It blocks very easily in the mixing elbow and seems to be a common problem from reading the other threads and forums. When I clean it I basically punch it out with a screwdriver and coat hanger to clear the entire mixing elbow. Then she runs clean and smooth until the next clog.
