Evening all
after some thoughts of where to head with a problem we are having.
this morning, we pulled away from our overnight mooring at tick over past moored boats. After 5 minutes, the engine overheating light/buzzer come on.
we paused to sort out drinking water and toilet and turned off the engine.
after 10 mins, we decided to try the engine again to pull away from the service point. The buzzer didn’t restart, we left it running for 15 mins without issue, so carried on our way.
stopping for lunch and some shopping, when restarting, the same symptoms, warning buzzer after a few minutes, turn off the engine and wait 10 mins then it ran fine.
we’ve been out for a week working round the four counties ring without any other issue.
engine water level was fine on the daily check.
There is water in the bilge, but it looks canal water dripping through the stern tube.
We were having this issue before, I changed the thermostat and flushed the engine block through with fresh water. The problem went away.
Any suggestions of what might be the next item for testing?
