News for today. Early this morning, we received a message from our client on the other side of the ocean. He sent over 12 disassembled used spare‑parts of a marine gearbox. From his voice note, we could hear his urgency.Local technicians have limited experience in marine gearbox repair and were stuck with this unit. Most components were badly damaged, and even if repaired, it would take an extremely long time.I fully understand how important this marine gearbox is to our client. After extensive discussions regarding working hours and operational efficiency, we finally agreed to ship a complete gearbox assembly. This delivers a fast solution.It is not merely about higher costs for the marine gearbox. More importantly, it prevents future breakdowns and keeps the vessel operating continuously.Multiple model references are shared here. When placing orders, please select products according to technical performance parameters.Should you have any questions, feel free to contact our technical support: 008613335181366.We welcome your suggestions and custom requirements for marine gearboxes.

Model Examples: HC100, HC138, HCD138, HCQ700, HCD600A, etc.
Features: Wide power range from 10kW to 3000kW, broad gear ratio coverage of 1.5‑24:1. Suitable for heavy‑duty vessels such as various cargo ships, fishing boats and work boats; also applicable for medium‑&‑small high‑speed vessels including yachts, traffic boats and passenger ships.
2. GW Series (German‑technology introduced)
Model Examples: GWC, GWD, GWS, GWH, GWL, GWK (e.g. GWC60.74B, GWC60.74B with PTO, GWC85/100, GWL36.39JL, etc.)
Features: Complete specification portfolio for large‑size vessels including cargo ships, engineering vessels and fishing vessels. Certain models are custom‑built for dredging operations (e.g. GWL36.39JL) or equipped with PTO (Power Take‑off, auxiliary power output).
3. GC Series (including sub‑series: GCS, GCST, GCSE, GCH, GCD, etc.)
Model Examples: GC Series, GCST44, etc.
Features: Classified by input‑output layout configuration. Applied to bulk carriers, oil tankers and container ships. Some variants such as GCST44 are controllable‑pitch propeller gearboxes for trawler fishing boats.
4. 2GWH Series (Dual‑engine Combined Drive)
Model Examples: 2GWH Series
Features: Dual‑power input & single‑power output. Designed for marine main propulsion systems requiring twin‑engine combination for higher energy efficiency and operational safety.
5. Two‑Speed Marine Gearbox
Model Examples: SGW42/45
Features: Two reduction ratios for ahead running. Speed shifting between high‑speed and low‑speed gears. Used on trawlers and cargo ships to improve diesel engine fuel economy.
6. Electric‑Propulsion Gearbox (DT Series)
Model Examples: DT Series (e.g. DT10000/1), EDB160, etc.
Features: Form main marine propulsion system together with propulsion motor and fixed‑pitch propeller. Fit for sightseeing cruise ships, fishing boats and passenger vessels. Models such as DT10000/1 are high‑power electric‑propulsion gearboxes with extremely high output torque.
7. Other Segmented & Custom Mod
els
Model Examples: 06/16a/26 Series, MA Series (MA100/MA125/MA142), MB Series (MB170/MB242/MB270A), 40A, 120B, 135, 300 Series, 400 Series, 800‑1000 Series, 1100‑1200 Series, JL360, etc.
Features: Covering light‑duty high‑speed marine gearboxes, standard marine gearboxes and various non‑standard custom‑made units, to satisfy diverse vessel types and engine‑room layout requirements.
Note: Hangzhou Advance marine gearboxes cover extensive model ranges. Actual model selection shall be determined based on marine main engine power, rotational speed, required reduction ratio and practical working conditions (PTO requirement, two‑speed demand, etc.).
