Description
Overview of V-Drive Gears
V-Drive gears in the 29–70% range, 1 1/2 inch wide, give marine engineers precise ratio control for Argo billet case gearboxes. Argomarine machines these gears from EN36A steel to deliver strength, wear resistance, and long service life. This series covers part numbers AM2029, AM2033, AM2038, AM2042, AM2048, AM2052, AM2058, AM2062, and AM2070. Because the gear profiles are cut accurately, you achieve smooth engagement and reliable driveline performance.
Features
-
Ratio options: 29%, 33%, 38%, 42%, 48%, 52%, 58%, 62%, and 70%.
-
EN36A steel construction provides high surface hardness and core toughness.
-
1 1/2 inch width suits the newer billet case gearbox design.
-
Quarter key hub for positive location on the shaft. In addition, precision machining reduces vibration and improves durability.
Specifications and Materials
Each gear measures 1 1/2 inch wide and uses EN36A steel with a case-hardened surface to withstand high torque and cyclic loading. Consequently, the gears maintain tooth accuracy under continuous service. The hub accepts a quarter key for secure drive.

Compatibility and Fitment of V-Drive Gears
Use these gears in Argo billet case V-Drive gearboxes where 1 1/2 inch wide gearing is specified. Select from AM2029 (29%), AM2033 (33%), AM2038 (38%), AM2042 (42%), AM2048 (48%), AM2052 (52%), AM2058 (58%), AM2062 (62%), or AM2070 (70%) to match vessel performance goals. Therefore, workshops can tune for stronger acceleration, efficient cruising, or heavy-load handling as required.
Compliance and Safety
Follow the gearbox manufacturer’s torque sequences and lubrication requirements. Always wear gloves and eye protection during handling. Furthermore, verify backlash, check tooth contact pattern, and run the driveline at low speed before full load.
Marine Applications
These gears serve workboats, cruisers, and performance craft that need predictable ratio changes. For example, lower percentages help long-range cruising, while higher percentages support towing, holeshot acceleration, or high-speed operation. As a result, both professional repairers and experienced DIY owners rely on this range during gearbox rebuilds and upgrades.
Why Choose Argomarine
Argomarine pairs EN36A steel with tight machining tolerances to deliver dependable V-Drive components. Moreover, the 29–70% ratio spread gives you flexibility without compromising fit or finish. When reliability at sea matters, these gears provide a proven solution.
