They do look very alike, but there are a few external marks that seperate them.
1.On the 717, MD-90 and MD-87, the tail extends for about a foot on top of the horizontal stablizer.On DC-9 and MD-80 it barely goes above.
2.The engines(BMWs) on the 717 are much wider than the JT8Ds on the DC-9.

Other than the tail differences, note the shape diffs between the JT8Ds and the BMWs. They're similar in shape to the MD-90s IAE engines--shorter and somewhat fatter in contrast to the longer slimmer nacelles of the JT8Ds
