From luxurious pleasure craft to stealthy military
vessels to hard working tugs, pushboats, fishing
boats, crew boats and supply vessels. Twin Disc
products optimize the control of the engine’s
horsepower, contributing to the boat’s overall
performance, productivity, operating efficiency and
cost-effectiveness.

Twin Disc marine products propel all kinds of

vessels, on all kinds of water, all around the world.
 NOTHING ELSE COMES CLOSE.
It took the vision and determination of acknowledged
mechanical innovator and offshore racing enthusiast Howard
Arneson to perfect the performance and reliability of surface-
piercing propulsion. It took Twin Disc to further realize the
extraordinary capabilities of Arneson Surface Drives for non-
racing capabilities — pleasure craft and commercial vessels, as
well as military applications.

No other marine propulsion system is so adaptable to such

a wide range of engine sizes and types. There’s an Arneson
model designed specifically to fit virtually every powerplant
option, accommodating torque outputs exceeding 30,000 lb-ft.

Arneson Surface Drives are the fastest, most efficient,

fuel-friendly propulsion systems on the planet. When
combined with Twin Disc QuickShift transmissions and EC300
control systems, Arneson surface drives allow you to control
your vessel from almost 1 knot to full speed with just a single
stroke of the lever.

 Don’t Buy Your Next Boat Without EJS™
The Twin Disc EJS (Express Joystick System) absolutely
revolutionizes docking and slow speed maneuvering of diesel
powered, conventional shaftline boats.

With easy fingertip movements you control direction and

speed — instantaneously and intuitively. No lugging.
No lurching. No clunking. All thanks to proven QuickShift®
transmission and EC300 control technology.

The EJS smoothly and simultaneously actuates and controls

engines, transmissions and thrusters. You can effortlessly
move the boat in any direction and even pivot it on its
own axis. Its performance dramatically exceeds any other
propulsion system. EJS brings incomparable control and
enjoyment to even the most difficult docking situations. Once
you try it, you can’t imagine driving your next boat without it.

ULTIMATE PROPELLER PERFORMANCE.

Since 1963 the name Rolla has been synonymous with the
highest quality, most efficient propellers in the world. What
started with Philip Rolla individually designing and crafting
race-winning propellers has grown to become the leader
in propeller technology for high-performance pleasure and
commercial craft as well as military vessels.

Rolla stainless steel and NiBrAl propellers range from

16 inches to 10 feet in diameter and are specifically
designed for high-performance submerged and Arneson
Surface Drive applications.

Rolla offers a wide variety of service for every aspect of

propeller design, manufacture and application, from complete
hydrodynamic analysis and engineering capabilities to
computational fluid dynamic (CFD) hull analysis to sea trials.

 SeaProp 60 saildrive

The SeaProp 60 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 SeaProp 60 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.
Gone is the propeller shaft, along with its attendant coupling,
stuffing box, cutless bearing, stern tube, and strut. Also
eliminated are the alignment procedures required between
the engine and shaft that must be done on the production line.
The SeaProp 60 can easily be mounted facing forward or
aft. Because it isn’t constrained by shaft angle or aperture
location, and it offers the builder more versatility in engine
placement and a smaller ‘footprint’ (no shaft, stuffing box, or
strut aft of the engine).
Boat operation will benefit from increased propulsion
efficiency with the SeaProp 60 saildrive. Unlike conventional
drivelines, thrust is parallel to the boat’s waterline, whereas 191
the downward angle on a standard shaft means that some of 59.65 131

 MARINE CONTROL DRIVE (MCD)
With over 30 years of research, development and operation,
the versatile Twin Disc Marine Control Drive (MCD) has
proven its worth in a wide variety of workboat applications,
including tugs, offshore supply vessels, double-ended ferries,
icebreakers, dredges and fire fighting vessels.
