At that draw length and weight with the string accesories, 238 is definitely possible.

With such a light arrow that speed is kinda low. Although 47# KE is low, it is at least above the recommended bare minimum of 45#.

Replacing whiskers with string leeches, removing the shooting loop (therefore increasing draw length which in turn increases weight), and/or possibly trying something like a no peep in place of the regular peep should get you up to 250 or so.
