I will find out tomorrow what type of service has been done on the motor over the years.

As far as engine hours are concerned, since there is not an hour meter on the boat the owner could only provide an estimate based on his very limited usage of the boat. However, the only real way to tell is to download the ECU. A few of the good surveyors in this area have the Merc software on their laptops and would be able to give specifics.
