Question hoping to get an idea where to start.
I have a 2004 Honda 150 that after running around 5 minutes at 4k-5k rpm the temperature alarm sounds. The motor is not hot and if I turn the key off and back on its good for another 5 minutes or so at the same rpm range.
I can run all day at 1k-3k and no alarm.
I bought this motor used and the alarm has gone off since I installed it. Before I ran it I a did maintenance and changed impeller, thermostat, oil, high and low pressure fuel filters, plugs.
I did notice that my water separator on the motor does not have any sensor leads on it and I thought I recalled seeing that on another BF150. May not be related but adding that note anyway.
Any input would be appreciated.
Thanks
Gene
