This evinrude outboard was not getting to operating temperature. I first check for a thermostat. Then I check the water flow. The reason I check water flow was the engine was bought with no thermostat and no temperature switch. I thought it might have been getting hot and both were taken out. As you can see the water flow is good. I will still keep a close eye on it to make sure it does not run hot.
