I am looking at a 1994 Tartan 31.
Any concerns about the 19 HP Westerbeke diesel having enough power for the boat?
Any reliability concerns?

Should be adequate power. Common rule of thumb is 1.5 to 2 HP per thousand pounds of displacement. I believe the T31 is about 9000 lbs light so you are in the upper end of the range.
