For decades, ZF has consistently produced reliable, high-performing marine propulsion systems. Known for engineering that emphasizes quality and reliability, ZF offers equipment that meets the demands of both recreational and commercial sportfishing boat operators, while maintaining an extensive global support network.
ZF’s marine transmissions earned their industry-leading reputation through exceptional responsiveness, smooth operation, quick shifting, and long-term durability. Engineered to support engine outputs up to 16,000 hp across vertical offset, down-angle, coaxial, and
v-drive configurations, precision-crafted ZF gears ensure quiet operation and an extended service life on the water.
Continuing that commitment to innovation, ZF offers an innovative ZF 3100A repower transmission series, purpose-built for sportfishing vessels. Delivering a massive power range from 1,900 to 2,444 HP at 2,300 RPM, the ZF 3100 A features a lighter, compact footprint that weighs 240 pounds less than comparable products. With its 10-degree down angle and reduced overall dimensions, it allows owners to install engines lower in the vessel, freeing up critical space for larger power plants or auxiliary equipment during repower projects and new construction. The shorter vertical offset of the ZF 3100 series allows vessels of yesterday to repower with today’s larger, more powerful engines.
This balance of compact design and dependable power is why world-class custom builders partner with ZF. Featured in ZF’s Profiles from the Helm series, Randy Ramsey, founder of Jarrett Bay Boatworks, built his legendary sportfishing brand by pairing handcrafted Carolina boatbuilding with proven ZF propulsion technology.
From early custom hulls to championship sportfishers like Marlin Fever – the winner of the 2026 Big Rock Blue Marlin Tournament – ZF transmissions provide the speed, precise low-speed maneuverability, and tournament-grade durability required offshore.
“ZF supports inboard sportfishing vessels ranging in size from 30 to 100+ feet and we understand intimately how critical it is for the boat to perform with precision, whether you’re in a tournament environment or spending quality time on the water with friends and family,” said Keith Stanley, ZF’s senior manager – pleasure craft product line.
Every project is supported by ZF’s experienced, in-house engineering team. Backed by knowledgeable technicians, a 24/7 hotline (833-ZF-WRENCH), and the ZF Marine mobile app, ZF prioritizes operational longevity and seamless integration across every vessel platform.
“We try to make the ownership experience as predictable and low-maintenance as possible,” Stanley emphasizes. “When you install a ZF transmission, you’re getting a product with a proven service history, and a partner who will stand behind it. And, hopefully quite a few fish reeled in along the way.”
