MM W20000

Product catalog summary

Overview
The document describes a robust marine transmission system designed for continuous duty in workboat applications. It is fully tested, reliable, and easy to install, complying with ISO 9001 standards. The system features a reverse reduction marine transmission with hydraulically actuated multi-disc clutches and is compatible with all engine and propulsion systems, including both Fixed Pitch Propeller (FPP) and Controllable Pitch Propeller (CPP) applications.

Specifications

Case hardened and precisely ground gear teeth for durability and smooth operation.
Output shaft thrust bearing designed for maximum propeller thrust in both directions.
Hydraulic shifting with a control lever for various operating systems.
Suitable for twin engine installations with the same ratio and torque capacity in both directions.
Emergency "get home" capability.
Robust cast iron casing and free-standing design.
Includes an oil cooler with fittings and flexible hoses, and integrated brackets.

Options

Engine-matched torsional coupling.
Propeller shaft flange and coupling bolt sets.
Classification by major Classification Societies upon request.
Power Take-Off (PTO), live or clutchable.
Trolling valve for slow-speed drive.
Shaft brake and electric clutch control (24 VDC).
