"Hi,
I have a 1992 Yamaha 175hp outboard motor, the alarm sounds that is in the control box. The motor runs well without any issue until you exceed 4000rpm for a period of time. The bottom left indicator on the tacho light ups indicating a temperature problem. Leave the motor running in neutral for approx. 15 to 30 seconds ceases the alarm. (also keeping the engine revs below 3500 revs will not activate the alarm).
I have changed the impeller and the thermostats and I still have the problem.
Any ideas as to the cause of the alarm?"
