Not long ago, while motoring down the
ICW, had a red warning light come on on the
engine panel in the
cockpit. After some struggling to figure out just what it was (damn poor
engine gauges on these boats), I determined it was poor
water flow. Steam coming from
exhaust, ect. So I jumped on this board and read everything I could on
Yanmar 2qm
cooling. I ordered an impeller, thermostat, figured how to clean the strainer, ect. However, it was none of the above. It was a problem so exotic and rare that none suggested the possible culprit. It was a loose
water pump belt. Took maybe 10 minutes to fix. So now I have a spare thermostat, impeller, and new knowledge. That is all.
