Yanmar 4JH3E life expectancy

I am interested in buying a 2005 43' from a charter company. The engine is a yanmar 4jh3e with probably 3500/4000 hours. What is the expected number of hours you should get from this engine if the maintenance is done as it should be done and a normal wear and tear.

I know that actually it has probably been abused a few times, but this is not quantifiable.

Thanks

Bon Vent !

From what I've seen, Sunsail and Mooring in the Caribbean do a pretty good job of maintaining their engines with frequent fluid changes and inspections, but the engines do get treated pretty hard. Good luck on maintenance logs, when I asked them for maintenance logs I got a blank stare and then then a hearty laugh.
The hours shown are pretty average for a boat coming out of charter. If you have the chance, opportunity and are willing to make the effort see if you can talk to the actual maintenance people about your (potential) boat, they will know each boat and each engine and won't be shy about discussing issues, particularlly over a drink or two. Even after several years I met technicians who still remember what they did on my previous boat; and this was at Sunsail/Moorings BVI where they have several hundred boats!

It all really depends on the quality of the maintenance.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
