Marine Gears For Sale

0 vessels available in Engines

Ocean Marine offers used marine gears and reduction gearboxes for sale, essential components for connecting marine engines to propeller shafts. Marine gears are available in a range of reduction ratios and shaft configurations.

Reduction gearboxes allow high-RPM diesel engines to drive large, slow-turning propellers at the optimal efficiency point, and are critical to the propulsion system of virtually every commercial vessel. Common brands in our inventory include Twin Disc, ZF Marine, Reintjes, and Hundested, covering a wide range of horsepower ratings and shaft output configurations.

Used marine gears are most commonly sourced when vessels are repowered, converted to different drive configurations, or decommissioned. Buyers sourcing replacement gears should confirm input shaft dimensions, reduction ratio, output flange configuration, and compatibility with their engine model. Contact our team to discuss marine gear specifications, service history, and current inventory available for your vessel repowering project.
