Does the panel have any views of the Volvo D9-575 engine? Good or bad? Anything to watch out for? What would be considered high hours? Can they be rebuilt?
Not aware of any common problems.
Of course there all the usual problems that CAN happen, blocked heat exchangers, EVC going evil etc.
Engine Survey and sea trial should pick up any issues.
More than 3000 hours I would class as “high hours“.
