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 various engines and propulsion systems.

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 control lever for push-pull cable or other systems.
Suitable for twin engine installations with the same ratio and torque capacity in both directions.
Emergency "get home" capability and robust cast iron casing.
Free-standing design with an oil cooler, fittings, and flexible hoses.

Options

Engine-matched torsional coupling.
Propeller shaft flange and coupling bolt sets.
Classification by major Classification Societies upon request.
SAE 0 or SAE 00 bell housing.
PTO (live or clutchable), trolling valve for slow-speed drive, shaft brake, standby oil pump, and electric clutch control (24 VDC).
