Lewis joins the club from fellow Evo-Stik North side Goole AFC. After joining The Vikings in September 2016, he has scored three goals in 16 appearances.
The 21-year-old has previously played for NCEL side Brigg Town and with the reserve side at North Ferriby United.
Boro boss Steve Kittrick said: "Lewis trained with us this week and has looked sharp. He likes to play just off the front man and has scored a few goals for Goole since September, so he will be a useful addtion for us going forward."
