TwinDisc Marine application

Only Twin Disc combines in-depth knowledge of pleasure craft, commercial and military marine applications with engineering excellence in transmissions, propulsion systems and controls. And only Twin Disc offers so many ways to make your craft move through the water more efficiently, with more control.

Marine Gears Twin Disc

Twin Disc supplies the commercial, pleasure craft and military segments of the marine market with transmissions, surface and waterjet drives, propellers and electronic controls. No one in the world offers you more ways to make your craft move through the water more efficiently, more reliably, with more control. So if you want to make the most of your boat, put Twin Disc aboard.

Propulsion control

Product Families to Fit Your Application

The fifth-generation EC300 Power Commander, based on nearly four decades of Twin Disc marine propulsion control expertise, is one of the most flexible, adaptable systems available. Developed with our experience with thousands of pleasure craft and commercial craft applications, it can be programmed to fit most specifications, including associated USCG or Survey Society regulations.

Rolla Propellers

Dedicated propellers with value added engineering

Rolla services could best be described as the performance at time of sea trials which is the result of working with the shipyard through the whole propulsion process which in an ideal situation would also include the CFD analysis of the hull.

Arneson Surface Drives

For the ultimate in speed, maneuverability, efficiency and dependability, nothing matches Twin Disc Arneson Surface Drives. Their surface-piercing propeller design reduces underwater drag by 50% compared to conventional submerged propeller drive systems. The only surfaces to contact the water are the propeller blades and a protective skeg. This results in higher overall speed, quicker acceleration and a better payload-to-power ratio. And 50% less drag significantly improves fuel economy while lowering operating costs.

Sail Boat Drives

The SeaProp60 saildrive is a propulsion system for sailboats with engines rated up to 56 kW (75 hp) @ 3600 rpm. Sailboat manufacturers and operators alike benefit from this system's unique but proven design.

With a SeaProp60 saildrive, the sailboat manufacturer will overcome inherent limitations and problems of conventional inboard shaft drive installations with a quicker, more versatile and simplified engine installation process.

Marine Control Drive (MCD)

The Marine Control Drive or MCD is a variable speed drive available in a range of sizes with power capacity from 160 to 4500 kW (215 to 6035 HP) at 1800 RPM. The MCD has proven its worth, particularly in tug applications but also in ice breakers, dredgers and fire fighting vessels. The system provides distinct operational advantages for any vessel requiring accurate positioning or a high degree of slow speed maneuverability while the main engine powers another action. There are three sizes with five models for each size to cover the range up to 4500 kW.
