That is nothing if the person did the required maintencance. I would say the same thing for a boat with 75 or 1000.
To put it into perspective, my wife's family are Watermen and have many boats, mostly 50+ ft boats with Diesels, but their smaller "skiffs" are 22-25 ft boats with mercuiser's in them from the early 80's. They have been running every day for the past 25 years. When I ask them what they think the hour counts are, they say its gotta be over 10,000 'cause they like to swap out the big engies 50,000k hrs. Her Grandfather's personal clamming rig has the same Detroits from the early 70's and he still runs the, wide open.
They are totally baffled when I tell them that my customers have a good year if they get over 100 hrs
