Side Power SRP130/250T 24V Proportional Retractable Thruster

The Side Power SRP130/250T proportional thruster is a 24V retractable marine maneuvering thruster rated at 130 kg / 286 lb of thrust. The retractable design allows the thruster unit to deploy for maneuvering and retract into its installed position when it is no longer required.

Unlike a fixed tunnel thruster, the SRP130/250T uses a retracting installation format. This makes the product a distinct option within Side Power’s thruster range and separates it from conventional tunnel-mounted bow or stern units.

The proportional configuration is another key part of the model. Rather than functioning only as an on/off thruster, the SRP130/250T is designed for use within a compatible proportional-control system. Its electrical configuration is 24V, and the listed thrust rating is 130 kg, equivalent to 286 lb.

The unit can be applied in compatible bow or stern thruster installations according to the vessel’s system design. This listing refers to the thruster itself and should not be interpreted as a complete installation kit with every control, wiring or mounting component.

For vessels specified around a retractable proportional thruster, the Side Power SRP130/250T combines 24V operation, 130 kg / 286 lb thrust and a retracting configuration in one marine thruster unit.

Key Features

• Retractable bow or stern installation — Designed to deploy when maneuvering and retract into the hull when not in use.
• Proportional variable-speed control — Allows the operator to apply only the amount of thrust required instead of operating strictly on/off.
• 130 kg / 287 lb nominal thrust at 21V — With up to 160 kg / 353 lb at 24V according to Sleipner’s current specifications. Sleipner Group
• 24V DC electrical system — Designed for compatible 24V marine electrical installations.
• 250 mm retractable thruster diameter — Uses a 250 mm / 9.84 in internal diameter.
• Twin Q-Prop™ propellers — Twin-propeller configuration designed to provide substantial thrust within the 250 mm diameter. Sleipner Group
• S-Link™ control system — CAN-based communication system with plug-and-play control cabling.
• PPC520 PRO™ power controller — The historical Side-Power documentation specifically pairs the 24V SRP130/250T with the PPC520 controller. Tempo Marine Service ApS
• Hold function — Compatible PRO controls can maintain selected thrust, particularly useful in dual bow/stern installations.
• Fast retract/deployment mechanism — The 250 mm retractable platform uses two actuators to handle the deployment mechanism. Sleipner Group
• Bow and stern compatible — The manufacturer specifies the platform for either installation position.
• Suitable for motor and sail boats — Manufacturer guidance places the unit typically on vessels approximately 43–62 ft / 13–19 m.
• Overheat protection — PRO variable-speed systems can reduce output to manage temperature and extend operating time.
• Sealed drive lubrication — Gearleg is pre-filled and uses long-term mechanical sealing.
• Flexible coupling — Helps compensate for minor drivetrain misalignment.
• Safe Start-Up / Child Safety — Supported through the compatible Sleipner control system.
• No tunnel drag while retracted — Unlike a conventional fixed tunnel opening, the retractable configuration withdraws the thruster when it is not required.
