The Redbacks sit atop the Cricket Shepparton Clyde Young Shield table after two rounds, racking up 8-237 on the back of McKenzie's 103 and dismissing the Bloods for just 101.
With three sixes and 12 fours, almost two thirds of McKenzie's knock came in boundaries, and he was ably assisted Tim Nelson (44).
Kanwal Singh (4-25) and Jason Parsons (3-4) did the damage with the ball for Kyabram, while Tristen Murray (4-35) and Michael Mandaradoni (28) were Karramomus' best performers.
Katandra is also undefeated after two matches and is on top of the one-day ladder after completing a tight victory against Old Students.
The Eagles made 138 with Clayton Simpson (36) top-scoring before the Students were bowled out for 131, despite 53 from Matt Harris.
The star of the fixture though was certainly Dante Fichera, who snared a hat-trick for the Students and finished with 3-29.
Ross Hammer (3-25) also claimed three wickets for the Students, with Karl Rosevear (2-12) the pick of the bowlers for the Eagles.
Pine Lodge kept its record perfect with a five-wicket win against Central Park-St Brendan's.
Steven Van Taarling's 65 not out helped the Lodgers cruise to victory in the 29th over, comfortably chasing down the 130 the Tigers made.
David Keenan (18) was the top scorer for the Tigers and Nick Younghusband took 2-2.
Travis Knight (35) supported Van Taarling well with the bat.

An unbeaten 85 from Darcy Collins helped Northerners to a 45-run win against Tatura.
Tatura threw everything at the opener with the ball - using nine bowlers - but could not find a way to dismiss him as the Jets compiled 6-208.
