The Revolution began their comeback in the 42nd minute, however, with Bou scoring first from a Brandon Bye cross.
Three minutes after halftime, Bou scored again from a penalty kick earned after Larrys Mabiala fouled Buksa in the box.
The Revolution added to their lead just three minutes later, with Bou continuing his strong streak with an assist to Buksa's goal.
New England maintained dominant form to finish out the match, ending a five match preseason with a record of 2W-2L-1T. Portland ends preseason with a second consecutive loss, but with a winning record of 4W-2L-0T in six exhibition matches.
