Description Q-PROP™ Q-PROP™ has been measured to reduce noise by up to 75% in controlled environments. The five-bladed propeller reduces noise levels while maintaining excellent performance. Some thruster models even show an increase in thrust. Expected noise reduction in average installations: 20–40% Upgrade kits are available for most SLEIPNER® Side-Power thruster models with special adapters. INTELLIGENT POWER CONTROL SLEIPNER® Side-Power’s patented intelligent power control provides minimal delay between thrust directions, reducing wear on mechanical parts while monitoring solenoid valve functions. In the event of a valve “lock-up,” the thruster automatically stops without any additional user action or main switch control. OVERHEAT PROTECTION When high temperatures are detected, On/Off thrusters automatically shut down to prevent overheating. PRO™ thrusters with speed control provide longer operating times by reducing power to maintain a safe temperature. FLEXIBLE INSTALLATION SLEIPNER Side-Power offers installation flexibility to utilize available space. Their models allow installation at any angle in the tunnel, adapted to fit the available space on your vessel. ANALOG SLEIPNER® Side-Power’s analog signal cables, with Plug & Play connectors, are color-coded to match wiring diagrams, featuring high-quality connectors that ensure correct installation. GALVANIC SEPARATION Parts submerged and exposed to seawater are galvanically isolated from the vessel’s electrical system, eliminating unwanted current flows. SEALED DRIVE LUBRICATION The thruster’s gearleg is pre-filled for lifetime lubrication and sealed with a long-lasting mechanical seal featuring ceramic and carbon fiber surfaces for ultimate protection against water ingress. FLEXIBLE COUPLING The flexible coupling protects the thruster’s drivetrain, compensating for minor misalignments between the electric motor shaft and the gearleg. DUAL PROPELLERS Dual propellers can offer greater thrust compared to a single propeller system within the same tunnel diameter. This system is utilized in SLEIPNER Side-Power’s mid-range models, where high thrust is required in small tunnel diameters. Thanks to their compact design and high efficiency, dual propeller models have become the first choice for boat builders worldwide.
