Wroxham set up a mouth-watering semi-final clash with Norwich United as they strolled to victory over underdogs Scole United.
A slice of luck on eight minutes allowed the hosts to take the lead.
A poor touch from Edward Cussens allowed the lurking Jamie Forshaw to steal in, the striker hitting an effort from the edge of the box that struck a bobble and lifted over the downed Ben Buckmaster in goal.
James Edwards then forced Ollie Sutton into a smart stop at his near post as Scole threatened, before Christy Finch made it 2-0 on 23 minutes with a superb lofted finish.
Forshaw curled in a superb 25 yard effort on 37 minutes to hand complete control to the Yachtsmen, something they kept hold of for most of a drab second period.
The game burst into life on 72 minutes as Remy Gordon raced onto Forshaw's through ball to fire through Buckmaster for 4-0, before a late consolation strike from David Coleman left nothing but a blemish on the scoreline as Wroxham strolled into the next round.
