For decades, ZF has been the quiet force beneath the waves, powering everything from sport fishing boats to commercial giants with marine propulsion systems that simply don’t quit. They’ve earned their reputation by obsessing over quality and longevity, delivering equipment that stands up to the toughest demands while boasting an unrivaled global support network.
Engineering Excellence, Built to Last – Even Through Repowers
It’s no secret in the marine world: ZF propulsion systems are legendary. Their transmissions are renowned for their responsiveness, silky-smooth operation, lightning-fast shifting, and ironclad reliability. Whether you’re harnessing 100 hp or a colossal 16,000 hp, ZF has a transmission to match, with configurations like vertical offset, down-angle, coaxial, and vee-drive to fit virtually any vessel.
They even have repowers covered, with the recently launched ZF transmission series 3100 A – designed exclusively for sport fishing yachts. These models deliver massive power ranges, from 1,900 to 2,444 hp at 2,300 RPM, and they weigh less and are more compact than similar models.
“We designed the ZF 3100 A repower series to provide sport fishing boats with a transmission option that takes up less space with less weight, yet still provides incredible power while underway,” said George Lewis, head of product line commercial-fast craft, North/Central America and the Caribbean. “Whether an owner is looking to reclaim space for larger engines or wishes to reduce a boat’s overall weight, this robust, innovative gearbox is an ideal solution to gain greater speed and flexibility.”
No matter the ZF product, each highly engineered marine propulsion component is a masterpiece of precision, case-hardened with finely ground teeth for whisper-quiet performance and a service life that spans years, not just seasons. Plus, they integrate with all engine types and propulsion systems, including waterjets and surface-piercing propellers, ensuring that signature ZF performance.
Powering the Pros: ZF’s Edge in Sportfishing
When the stakes are high, serious boaters demand reliable, durable marine propulsion systems. That’s why ZF transmissions, controls, and propellers are some on the highest-performing sport fishing boats on the market, from head-turning Vikings to the recently unveiled luxury sportfishing yacht Scout 670 LXS.
With more than 11,000 hours on the water and 1,000+ blue marlin released, the 87’ custom-built Spencer sportfishing yacht Betsy operates with ZF pod drives and a ZF SmartCommand control system, coupled with four CAT C18As at 1150 hp each. Betsy was the first vessel to boast four ZF 4000 pod drives, which deliver unmatched maneuverability. The combination of these technologies allows Betsy to move through the water at 40 knots while providing super range, economy, and speeds.
Betsy’s owner Mike Brauser told Spencer: “…taking delivery of the boat, putting it to the test in some serious weather, and then to catch 153 Blue Marlin in 40 days simply blew me away!” His fishing abilities have led to multiple awards and honors, including the Billfish Foundation twice recognizing Brauser as the Atlantic’s top angler.

A Partnership for Life: Support Beyond the Sale
When it comes to keeping you moving on the water, ZF’s global support network is second to none. Imagine service technicians with over four decades of ZF experience – that’s the kind of deep product knowledge that gets you back on schedule, fast.
