Boston Town suffered their heaviest loss of the season despite taking an early lead.
Manager Chris Funnell says the Poachers are now in a relegation battle after being taught a lesson by promotion-chasing Shepshed Dynamo.
And yet it all started so well for the visitors when Matt Cotton gave them the lead after eight minutes, slotting home after Tom Siddons had delivered a dangerous cross.
Shepshed have long been a bogey team for Boston Town, who have never beaten them in 11 attempts – and they soon reasserted their dominance with two goal in two minutes.
First, their captain Declan Peart equalised from a corner after 15 minutes, and almost immediately afterwards Jiah Medrano gave the hosts the lead.
Shepshed repeated the trick of two quickfire goals in the second half. Medrano made it 3-1 after 65 minutes and three minutes later Chad Timson added a fourth with a spectacular strike from 30 yards.
Peart helped himself to his second after 79 minutes to make it 5-1 on an afternoon to forgot for the Poachers
