Silsden leapfrogged their hosts at the top of the Northern u19 Alliance West Division table with an impressive display.
After romping to a 3-1 half-time lead the young Cobbydalers had to withstand intense home pressure in which they forced a string of corners and saw a 25-yard curling effort slam against the bar.
Silsden dominated the first half with some superb inter-passing attacks and they left the league leaders chasing shadows.
A controversial goal on the stroke of half-time was the only blot on Silsden’s copybook. Goalkeeper Christian Paulat-Brigg looked to have cleared a cross-goal shot from Matthew Semley but the linesman flagged to say the ball had crossed the line.
Until then, the Cobbydalers had dominated.
Marshall Pedder put them ahead after only three minutes when he latched on to Chris Wademan’s through ball and blocked the goalkeeper’s clearance; the ricochet rebounding into the home net.
Joe Gaughan stroked home the second after 23 minutes when he took a quick free-kick, which trickled into the corner of the goal with the keeper still organising his wall at the opposite post.
And there was nothing the beleaguered keeper and his wall could do about the third goal seven minutes later, Gaughan slamming a 30-yard free-kick in off a post.
Emley dominated the opening 20 minutes of the second half but Silsden defended superbly and the game was over as a contest when Wademan broke free after 66 minutes to add a fourth goal.
Gaughan clipped the bar with a rising shot after 84 minutes but made no mistake five minutes later when he completed his second hat-trick inside a week for the Cobbydalers.
Bradley Fay should have added a sixth deep into stoppage time but fluffed his shot from two yards out.
The win leaves Silsden three points clear of their hosts with a perfect record of four wins from four games.
