The Devils are now in a strong position to push for a top six finish to earn a place in the end of season play-offs.
Team manager Lee Trigger said: “It was another good team performance with all the boys getting at least one paid win.
“Edward Kennett was very good for the Rockets, winning five of his six races but he did not have any back-up while we had only two races in which one of our riders failed to score.
“It was good to get a convincing win and score 50-plus points again.”
Morten Risager led the Plymouth scoring with 12 (paid 15) points from his six rides while 19-year-old Australian Jack Holder dropped his only points when he fell while challenging Anders Mellgren for second place behind Kennett in heat five.
Plymouth will be hoping to make the breakthrough into the top six next weekend with a visit to Redcar on Thursday and a home match against bottom of the table Scunthorpe on Saturday.
