Overheating, mechanics have replaced thermostat and impeller. Problem still exists. There is water coming out the hole in the side. The alarm goes off and it starts to cut out when I push the motor over 4000 rpms. The mevchanic I have now thinks it’s a piece of the previous impeller lodged up in cooling system and pressure when the engine is pushed up in rpms is causing it to block the cooling system. He is scheduled to take power head off to find the issue.
