To find the mean (average) of the diver's scores, we follow these steps:

1. **List the scores**:  
   \( 6, 6.5, 6.5, 6.5, 7, 8, 8.5 \)

2. **Add the scores together**:  
   \[
   6 + 6.5 + 6.5 + 6.5 + 7 + 8 + 8.5 = 49
   \]

3. **Count the number of scores**:  
   There are 7 scores.

4. **Divide the sum by the number of scores**:  
   \[
   \text{Mean} = \frac{49}{7} = 7
   \]

Therefore, the mean of the scores is **7**.
