"Greetings all, yesterday, aft
"Greetings all, yesterday, after a couple of hours running gently around a local clean fresh water lake, and a brief spurt at 3000 RPM I slowed for about a minute then put the engine astern. The temperature alarm on the remote immediately lit up and the alarm buzzer sounded continuously. The oil pressure light remained a solid green. I reduced to idle, the temperature light remained lit, as did the oil pressure green light. The coolant discharge was pumping healthily. I switched off, left the engine for 10 minutes, then switched the ignition on - without starting the motor. The temperature light lit and stayed lit. I started the engine - at idle the temperature light is lit, but no buzzer, at 1100 RPM the light is still lit, and the buzzer is yelling at me. The outlet temperature at the observation discharge is "hand warm" only, and the engine is in all respects (to my untrained eye!) normal. I was able to motor at 3kts the 4 miles back to the slip. The engine coolant discharge stayed "hand warm" and all was normal - except the temperature light was lit continuously and the buzzer went off as I nudged it over 1000 rpm going astern at the slipway. The inlet filters were found to be perfectly clean, the engine temperature cool and uniform. The Temperature light comes on immediately when the engine is cold this morning when I turn the key without starting the engine. I'm hoping this is just the temperature sensor but would really welcome some advice - and if it is the sensor - is this a standard Honda "automotive" type component or is there a special "marinized" one -I cant find it in any parts listings !
The engine has 120 hours on it, has only been run in fresh water, and has been regularly and well maintained.
Many thanks for reading to the end !
All the best
