Side-Power SH240 Hydraulic Thruster 240kg 250mm Twin Counter Rotating Q-Props
The Side-Power SH240 Hydraulic Thruster delivers up to 528 lbs of continuous, proportional thrust through twin counter-rotating Q-Props and S-Link digital integration, giving vessel operators total docking authority and unlimited runtime without thermal shutdown.

uperior Thrust & Flow Efficiency: Engineered Twin Counter-Rotating Q-Props
Master difficult close-quarters maneuvering and harsh tidal currents with the Side-Power SH240 Hydraulic Thruster. Engineered specifically for vessels ranging from 42 to 75 feet, this heavy-duty hydraulic thruster delivers up to 528 lbs (240 kg) of continuous propulsion force. Unlike traditional DC or AC electrical thrusters that overheat under extended usage, hydraulic operation provides unlimited run time at any power level—from gentle mooring adjustments to maximum thrust output. Controlled through Side-Power’s intuitive S-Link plug-and-play digital network, captains gain complete proportional control for smooth, precise docking in any conditions.
Hydrodynamic Performance & Multi-Unit Scalability
At the core of the SH240’s efficiency are twin counter-rotating 5-bladed Q-Props. These lightweight composite propellers reduce inertia during startup and stop sequences while pushing higher water volumes through the streamlined 250mm tunnel. The aerodynamic gear housing minimizes water turbulence inside the tunnel, maximizing hydrodynamic flow and system responsiveness. Integrated within a vessel's central hydraulic network or paired with a dedicated Side-Power engineered power pack system, the SH240 easily scales across bow and stern installations with GRP or composite pre-drilled tunnel kits.
Simple Installation, Sealed Gearleg, & Low Maintenance
Designed with compact internal dimensions to conserve vital interior hull space, the SH240 simplifies both initial mounting and ongoing care. The factory-sealed gearleg eliminates the messy task of filling oil during installation while significantly lowering long-term maintenance needs. A flexible mechanical coupling cushions the drive gear against impact forces, and easily accessible sacrificial zinc anodes allow fast replacement during routine haul-outs.
