Buy Marine Gearboxes & Transmissions for Diesel Engines.
Marine gearboxes are a critical component of any marine propulsion system, ensuring correct power transmission, speed reduction, and directional control between the engine and propeller. Coastal Wave Marine supplies new Yanmar marine gearboxes and marine transmissions for yachts, commercial vessels, fishing boats, and workboats, supporting both new installations and marine gearbox replacement requirements across a wide range of diesel engine applications.
Each marine diesel gearbox is selected through an application-driven process that considers engine power, torque, gearbox ratio, rotation requirements, duty cycle, and vessel operating profile. As a multi-brand sourcing supplier, we work with established manufacturers such as ZF Gearboxes, Twin Disc, Kanzaki, and PRM, allowing us to recommend OEM marine gearboxes based on technical compatibility and availability rather than brand preference.
In addition to gearbox supply, we support marine gearbox replacement and repower projects, including matching gearboxes to existing or new diesel marine engines, ratio selection for optimal propulsion efficiency, and export-ready supply for international delivery. Each marine gearbox is supplied with a focus on technical accuracy, serviceability, and dependable performance in real marine operating conditions.
