Had a new heat exchanger on my 3HM installed 2.5 years ago After over heat alarm went off on the maiden voyage. After noticing some extra smoke last few times out, I lost all water flow, sailed back into to slip. Turns out now Elbow completely blocked with crap few years latrer. Did not change anything only clean all is good now!
