Re: Yanmar coolant light on
Hey thanks for your response. It's raw water cooled. I have recently made a big trip on it where I had the engine running for hours on end and had no problem except on one occasion when I turned it I the light and alarm stayed on for a few minutes and then stopped so I thought it wouldn't be an overheating issue as it was in the beginning before it gets hot. However the last time it happened it came on after being on for five minutes so I got worried it was over heating and turned it off. I only bought the boat a few months ago so haven't myself flushed the coolant. The history of the boat shows that the previous owner had it serviced on an annual basis. I am a first time boat owner so am lacking in knowledge with this sort of thing, I don't even know how to flush the coolant!! Thanks again for taking the time to respond. If you have anymore ideas as to what I could do it would be much appreciated.
