You have asked a couple of questions.

1. I do not know what is meant by "2003 series model". It sounds like salesman talk.

2. 2700 hours works out to over 200 hours per season for 12 years use and is quite a lot in an auxiliary sailboat, probably indicates a southern boat.

3. A Yanmar (I own a 2GM) ought to be able to give good service with that number of run hours, provided that it has been maintained and serviced properly. A lube oil analysis and a compression check will help to verify its condition. Be sure to check condition of the cooling system very carefully, especially if it is raw water cooled.
