Nissan NS40D Compression.

I am going to buy this particular motor and compression readings are 97, 95, and 93. Are these readings too low or is it in good condition?

You are within 10% of each other, so it is not too bad.

BTW, Welcome to Iboats.

Compression for that model is 117 PSI. The PSI variation tolerance among cylinders should not exceed 15% max.

Happy Boating
