Veteran driver Mike Marlar’s nearly two-year stint piloting cars for Decorah, Iowa-based Skyline Motorsports is ending effective immediately, the 47-year-old racer from Winfield, Tenn., announced Thursday.

While revealing the news in a press release “after much consideration” and with “mutual respect and gratitude between all parties involved,” Marlar also announced that he will reunite with former car owner Ronnie Delk to race with sponsorship from Skyline Motorsports owner Greg Bruening. Marlar’s wife, Stacy, said Marlar’s focus is shifting to a pick-and-choose schedule with Delk in 2026 but it remains possible they will make a few starts together before the end of the ’25 season.

“This was not an easy decision, but one made with the best interests of everyone in mind,” Marlar said in the press release. “We are incredibly grateful to Greg and (teammate) Tyler Bruening and the entire Skyline Motorsports team, sponsors and supporters who have been part of this journey. The friendships and memories made will last well beyond our time competing as a team.”

Marlar joined Skyline Motorsports in November 2023 after Delk announced his retirement from team ownership and immediately reached victory lane, winning his debut run during the World of Outlaws Real American Beer Late Model Series World Finals at The Dirt Track at Charlotte in Concord, N.C. He went on capture seven features in 2024 — highlighted by a $50,000 triumph in the Jackson 100 at Brownstown (Ind.) Speedway — and three A-mains this season including a $15,000 WoO score on July 12 at Sharon Speedway in Hartford, Ohio.

Delk will return to fielding a Dirt Late Model for his close friend after a two-year absence from the scene. Marlar will also retain longtime crew members Josh Davis and Jerry Sprouse as he rekindles a successful decade-long pairing with Delk that included a 2018 WoO points championship.

Greg Bruening has not announced a new driver for his second team. He began fielding a second effort alongside his son Tyler in 2019, starting with Chris Madden of Gray Court, S.C., before swapping in Shane Clanton of Zebulon, Ga., for a relationship that lasted through the end of the 2023 season.
