MM W18000

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, adhering to ISO 9001 standards. The system features a reverse reduction marine transmission with hydraulically actuated multi-disc clutches and is compatible with various engines and propulsion systems, including both Fixed Pitch Propeller (FPP) and Controllable Pitch Propeller (CPP) applications.

Specifications

Case hardened and precisely ground gear teeth ensure long life and smooth operation.
The output shaft thrust bearing is designed to handle maximum propeller thrust in both forward and reverse directions.
Hydraulic shifting is smooth and reliable, with a control lever for push-pull cable or other operating systems.
Suitable for twin engine installations with the same ratio and torque capacity in both forward and reverse modes.
Includes emergency "get home" capability and a robust cast iron casing.
Free-standing design with an oil cooler, fittings, 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), either live or clutchable.
Trolling valve for slow-speed drive.
Shaft brake and electric clutch control (24 VDC).
