Certainly a lot of negatives out there, but I had a pretty good experience with mine.
As with any turbo-charged engine:
don't rev it prior to bringing it up to operating temperature
allow it to idle for 60 seconds prior to shut down
don't exceed 100 hrs. between oil
use best quality oil
In my case, the problems I had were with dis-similar metals causing corrosion
on the top of the engine. Not a deal breaker by any means, and relatively easily to correct.
I did have a fuel pump
fail, but I believe that was about 1400 engine hours.
These were some of the first turbo engines for sailors and I think the bad rap is equally shared among owners, marine
mechanics and the manufacturer. There seems that there was a failure by Volvo to properly train their resellers as to service
requirements, and they dropped the ball in regard to technical support for the guys in the field. And yes, I think there were some design issues too. Not every good truck engine makes the conversion to marine
use without issues.
I would have a good mechanic
, who is familiar with these engines
, to go over it carefully prior to installation
