"My Honda BF50A overheat alarm
"My Honda BF50A overheat alarm goes off at ~1800 rpm's.1st trip out of the year...buzzer sounded.Cleaned pee hole and 2nd trip it ran all day no problems.3rd trip...went off as soon as I hit 1800 rpms.Checked thermostat(OK),replaced water pump,cleaned pee hole grommet(was somewhat obstructed).Took it out for test run today and again,as soon as it hit 1800 rpms,buzzer sounded.Engine seems to run fine....water is warm but not extreme and it is peeing better than ever.Also,no overheat indicator light...just the buzzer.Any idea what I should check next???Perhaps the Thermo sensor is bad???Any advice would be appreciated."
