So I'm browsing some used boats on the Interweb yesterday...
The listing in question described the boat's engine
as recently replaced with 2900hrs on it (maybe they didn't use the recently, but anyway...), however in the pictures they happened to show a shot of the engine
hours meter which read well over 6000 hours.
I emailed the broker and he replied it was normal not to replace the engine meter during an engine replacement, so the meter didn't read the correct time.
Does that sound right? I have never done a replacement, and had never really encountered the issue before so I was a bit surprised. To me, if you were replacing the engine, a new meter would probably be part of the job.
