The Ducks dominated the game in terms of possession, adapting to the bumpy pitch much better than their hosts, but it took until the 44th minute for the first goal to come, when a corner from Phil Mason was met by a Scott Honeyball glancing header at the near post.
Another Mason set piece just after the hour mark brought the second goal, this time a free-kick headed in by the unmarked Peter Clifford.
A flurry of missed chances followed before Steve Callinan fired home from a Danny Honeyball through ball to make it three-nil with ten minutes left.
Peter Donnelly then wrapped up the game with a superb goal, dribbling past two defenders before unleashing an unstoppable shot into the top corner from almost thirty yards out.
