Bursey gave Poly a 7-0 lead on a 7-yard run midway through the first quarter.
Jackson's first TD pass gave the Jackrabbits a 14-0 lead.
Jackson then hit Bursey on a 22-yard TD on the team's first play of the second quarter for a 21-0 advantage.
Jabar Morris then scored on a TD run, giving Poly a 28-0 lead less than three minutes into the second quarter.
After the scoring outburst, the team's traded turnovers the rest of the half with Kahuku finally cashing for a safety one play after throwing an interception.
Jones started the second half for Poly by returning the kickoff 81 yards for a touchdown and a 35-2 lead. Only a few minutes later, Bursey scored for the third time as the Jackrabbits went up 42-2.
