Unchanged from their victory over Strathspey, Inverurie made it back-to-back wins at Harlaw Park with a hard-fought success against Fort William.
Andy Hunter put Locos ahead on the stroke of half-time, before a Joe McCabe double sealed the points.
Both sides shared possession throughout an evenly contested first half, with Inverurie attempting the first effort on goal after 15 minutes. Jordan Leyden fired wide from distance after being sent into the box by a Martin Laing through-ball.
Fort William forced the first save of the match through a 25-yard dipping effort from Iain MacLellan, though Scott Mathieson was able to track the flight of the ball and save it comfortably.
As the winter weather struck Inverurie, the players endured a lengthy hail storm. Leyden marked the passing of the shower with a free-kick from the edge of the box which was pulled wide of the near post.
This was quickly followed by another speculative MacLellan shot from distance which was once again gathered by Mathieson.
As the half-time break approached, Inverurie began to increase the pressure on the robust Fort defence, forcing a scrambling save off a Kyle Willox effort from outside the box.
Shortly afterwards, Locos broke the deadlock. Leyden supplied a dangerous cross to the back post which wrong-footed keeper Douglas MacLennan, causing him to fumble the ball as he attempted to catch it. Finding himself in the ideal position, Hunter calmly back-heeled the loose ball into the empty net from all of six yards.
After a slow start to the half, Inverurie finally took command of the match as McCabe put Locos two ahead with a towering header. Leyden provided the inswinging corner to the back post which allowed the advancing McCabe to head the ball back across the keeper.
Just seven minutes later, Locos moved three clear with a near identical goal from McCabe. Set-up from another Leyden corner, McCabe once again rose above the surrounding defenders from six yards out and his header found its way over a crowded goal-line.
