[QUOTE="Pappy, post: 522205, member: 3278"] [B]Would be good to know the exact model year of this engine as there were some late 70's engines that had a plastic tube near the top of the water supply to the powerhead that was prone to melting after an overheat. From looking at the parts breakdown yours has this as well and is #114 in the schematic. Very possible this is the cause of your issue. Secondly.....The thermostat on this engine cannot keep the telltale from functioning at all. Removing the thermostat housing and running the engine will tell you how much volume is being delivered to the powerhead but that is it. [/B] [/QUOTE]
