Evinrude 225 - Reduced RPM....

I have two pairs of 1989 Evinrude 225 engines - which ran perfect last year!<br /><br />This year one of them has some problems. No starting problems but after a few minutes sailing it falls out. The engine falls to approximately 2800 RPM, and is not going higher. Only after 5-10 minutes with the engine off, it’s ready again.<br /><br />I think it has something to do with the implemented heat sensor, that reduce the RPM to 2800 to protect the engine from overheating.<br /><br />However, the compression is fine, the water pump is working and the water is going out the engine again! <br /><br />Could it be related to the thermostat, although it looks fine – or have anyone experience something similar!?<br /> <br />Best regards,<br /><br />Bo

Just because its pumping water doesn't mean its not overheating. Does your alarm sound when the problem happens. Are you sure your alarm is functional.
