Twin Disc Pacific has been appointed the Exclusive Distributor for the innovative Seatorque Marine Propulsion Systems in the Pacific region.


In the spotlight, the Seatorque Boss Enclosed Shaft System which offers boat owners a myriad of benefits.

The multiple-award winning ‘Boss’, a product based on 14 years R&D, is a totally enclosed, oil-filled, self-contained, shaft and thrust bearing assembly, supplied as a complete unit from transmission output coupling to propeller end.

The non-rotating, full length shaft casing and thrust bearing assembly minimizes mechanical losses to only 2 percent, leaving valuable extra power where you want it, for propulsion.


The Boss further delivers unrivaled ruggedness in operation coupled with the lowest underbody drag of any system currently available.

Suited to commercial and recreational vessels from 30 to 200 feet, the Boss provides reduced friction, better efficiency and allows for the use of softer engine mounts reducing vibration. It bolts on to the hull transferring the thrust from the propellers to the hull and not back through the engine, meaning there is less pressure on the mechanical equipment.

The use of cardan shafts to attach Seatorque to the engine package  eliminates alignment issues, both during construction and post-delivery.

With the Boss, there are no outdrive-type appendages, vulnerable to damage if impacted or bottomed out and no costly multiple
propellers to damage in the event of contact with debris or worse.

Seatorque products, in particular the Boss Enclosed Shaft System, enjoy great synergy with the existing Twin Disc propulsion systems, working together to further reduce vibration and increase performance offering an exceptionally designed engineering solution.

International boat builders are using them to great effect, including Grand Banks, Outer Reef, Nordhavn, Fleming and  Marlow. Local builders are catching on too, and now, for the first time, Seatorque is represented in the pacific region, supported by the extensive and reliable Twin Disc Pacific network.

Executive Vice President of Seatorque Control Systems Jana Stolper says the appointment of Twin Disc Pacific as the Seatorque exclusive distributors for the Pacific region as a perfect alignment of brands and products. “At Seatorque our focus is on improving the performance of a boats propulsion and partnering with Twin Disc Pacific allows us to offer local boat owners a robust and effective engineering solution. At the same time we have a commitment to high levels of customer service and support and we know the team from Twin Disc Pacific can deliver this commitment to local boat owners.”

Glenn Frettingham, Managing Director at Twin Disc Pacific commented “Seatorque produce an exceptional range of enclosed shaft products that perfectly align with our Twin Disc propulsion systems, offering boat owners a superbly engineered solution for their boat.

“Twin Disc’s tagline and brand promise is ‘We put horsepower to work’. Adding Seatorque to our product mix means we can emphasise this focus and advance it further with improved performance through reduced vibration and a more efficient use of thrust from the engines and propellers.”
