What We Do

We are driven by success.

Seatorque equipment is designed for a variety of vessel types, offering dramatic reductions in driveline noise, vibration, underbody drag, engine load, fuel burn, and maintenance costs: whilst increasing operating range, ride comfort, reliability, and overall efficiency. Mechanical losses are kept at a minimum, leaving horsepower available where you want it...for propulsion, and not lost through driveline inefficiencies.

The BOSS, Bolt On Shaft System feature quick easy installation, with no alignment issues during construction, or post-delivery. BOSS systems have no horsepower restrictions, and are available in shaft diameters from 1" - 4" in standard production, with larger diameters available engineered to order.

The M4B, ST4B, and MX2 systems are an integrated gearbox to propeller solution, incorporating roller thrust bearings, in a non-rotating oil filled outer casing, eliminating drip-less seals, stuffing boxes cutlass bearings, and in many cases the need for intermediate struts.


Turbulent water flow to propellers is eliminated increaing propeller efficiency and reducing noise and vibration transmitted to the hull structure. With no shaft seals to leak, engine rooms stay clean and dry.


The MX1 system us also available as a no compromise alternative for both new construction and refit.


The BOSS system service/maintenance cycle is every 3 years, or 3,000 hours, whichever comes first.

Extended Warranty/Protection packaged are also available.
