sdx 270 ouboard

I am looking to purchase a 270SDX, OB-mercury 300, vd0 v8. I am a family of 4, can this boat be used to water-ski or wake board off of?

I’m looking at either the 270 or 290 STX outboard. I was wondering if anyone has any advice on which bout to get. My activity use case: General boating in and around Chesapeake Bay (usually in rivers), taking young teenage kids water skiing and tubing,, and maybe cross the Chesapeake bay 1-2x...
