Engine was running hot last year, replaced impeller last year, no change. pulled the thermostat, no change.
Started motor today and after one minute steam coming out of telltale. I pulled the thermostat cover and pulled the exhaust plate which is directly behind thermostat cover. The water ports were filled with muck. I started scraping all the ports I found 2 spots that were digging out. I kept digging with a metal coat hanger and 3 hours later I had 2 water ports cleared going around the cylinder. Blasted it out with the garden hose. Put it back together and now it runs cool. Telltail is now pumping alot of water.
