Seriously, lets put things in perspective here.
This French ****ter has 6000 plus hours on the engine.
Not too many posters here would even put 200 hrs a year on their own.
It is not a Gardner!
Here is a bit of perspective for you. Driving a car at 100 kmh for an hour = 100 klm. Assuming the boat engine is running mostly at cruising speed it is equivalent to driving a car at 100 kmh, therefore a marine engine with 6,000 on it is equivalent to a car with 600,000 klms on the clock.
Does that make sense??
Being a diesel and a Yanmar at that, I don't think 6,000 hours on it would mean it is worn out. With those hours at 6 knots, the boat has travelled circa 36,000 miles. Possibly that boat has been in a charter fleet for some time.
I saw a similar sized Kubota engine that had been running in a trawler as an auxiliary 24/7 and only ever shut down for oil and filter changes so similar running as a taxi and always hot. It had 26,000 hours on it and was still running fine.
The workshop stripped it, de-lipped the bore, linnished the crank, relapped the valves and reassembled it with new rings, bearings, seals and gaskets and sold it to a farmer to run his irrigation pump.
More marine engines in yachts die from underuse than overuse.
