Weymouth moved into the top five in the Evo-Stik League South Premier table on Wednesday night after hitting hosts Farnborough for six at The Rushmoor Community Stadium.
Harry Baker gave the Terras a great start with a goal in the 4th minute.
And 6 minutes later, Calvin Brooks doubled the visitors` tally, although skipper Josh Huggins responded for Boro within a minute to make it 2-1.
Baker added Weymouth`s third in the 26th minute, but a Mark Travers own goal 6 minutes later gave Farnborough hope going into the break.
On the hour-mark, the Terras made it 4-2 through Josh Carmichael and then added two more in the final 8 minutes from Brandon Goodship and Ben Thomson to make it a miserable night for the home side.
