Volvo D9 cylinder liners breaking.

[driver0606]

Looking for a replacement boat and having read some reports that Volvo D9s sometimes but rarely break cylinder liners, I was rather surprised when the first yacht with D9s that I inspected, a very well kept Prestige 50, had just had an engine rebuild at 400 hours for just that reason. It was not done by Volvo (they quoted 80,000 Euros) and probably not reported.

Considering that both engines had exactly the same life until the event, and wondering whether this is more frequent than reported, I walked away. Does anybody really know how often this happens and why?

Sum of the parts job , not one thing specific.
Its about attention to details and resisting the temptation to cut corners .

80k Euros looks more like the price for two new engines including installation than the cost of a single engine complete rebuild (and even then, just replacing the liners).

I guess obtaining access to the engines with a crane would be prettey expensive and I never fail to be surprised at the prices on the Cote d'Azur!

I have not had a flood of people with stories about D9s giving liner problems, so perhaps its uncommon. In any case, thank you for your comments.
