NOTICE
Do not operate the outboard motor when the overheat alert is 
displayed. Otherwise, severe engine damage could result.
Blinks when the engine temperature rises too high.
If the overheat alert blinks, stop the engine and check that the cool-
ing water inlet on the lower case is not blocked. Consult your 
Yamaha dealer if the problem cannot be located and corrected.

Consult your Yamaha dealer if the alert continues to blink even
though the oil level is at the proper level.
