SLEIPNER SX35 EXTERNAL STERN THRUSTER | 12V | 35-43KG THRUST | FOR TRANSOMS UP TO 50MM

The ultimate ultra-compact external stern thruster engineered for smaller vessels or tight hulls—no extensive fiberglass work required. The Sleipner Side-Power SX35 (50mm Version) is a highly versatile, self-contained external pod thruster designed specifically for motorboats and cruising sailboats up to 32 feet. Outfitted with a streamlined 50mm (1.96") mounting shaft structure, this model is explicitly built to effortlessly pass through standard-thickness solid fiberglass transoms and aluminum hulls up to 50mm in thickness.

The SX35 packs an impressive punch for its compact size, yielding a reliable 77 lbs (35 kg) of continuous thrust at a 10.5V nominal load, and ramping all the way up to 95 lbs (43 kg) of peak thrust at a full 12V charge.

Key Features:

• Standard 50mm Transom Capability: Engineered with a specialized short-reach mounting thread layout, this unit securely clamps through standard fiberglass transoms or aluminum plates up to 50mm (1.96 inches) thick without adding unnecessary bulk inside the hull.

• No Complex Glasswork / Easy Installation: Eliminates the need for traditional internal fiberglass tunneling. Installation only requires drilling small, clean mounting holes for the securing bolts and the main power cable entry sleeve.

• Patented Intelligent Power Control (IPC): Sleipner’s advanced microprocessor-controlled safety system provides a protective millisecond delay when switching drive directions to eliminate mechanical drivetrain shock. It actively monitors solenoid function and automatically kills power if a solenoid lock-in is detected.

• Whisper-Quiet Single Q-Prop™ Propeller: Features a state-of-the-art 5-blade composite skew propeller running inside a highly optimized 140mm (5.5") integrated tunnel. Paired with vibration-absorbing hull connection sleeves, this setup drops cabin noise and stern vibrations by up to 75%.

• Ignition Protected (ISO 8846) & Hermetically Sealed: Certified under ISO 8846 and UL 1500 standards. All electrical components are isolated inside a watertight composite casing, making it 100% safe to install on gasoline-powered boats or near fuel vapor lockers.

• Enhanced Hydrodynamic Water Cooling: Because the entire aluminum pod sits completely submerged outside the hull, it benefits from constant, rapid water-jacket cooling, resulting in significantly longer continuous runtimes per cycle than internal DC alternatives.

• Complete Galvanic Separation: Immersed aluminum and drive components are thoroughly isolated from the vessel's onboard 12V electrical ground network, terminating the threat of stray-current galvanic corrosion. Includes factory-installed anodes for immediate underwater protection.

• Zero Maintenance Sealed Lubrication: Features a lifetime-lubricated gearhousing running a heavy-duty ceramic-on-carbon mechanical seal face, guaranteeing total protection against saltwater intrusion.

Specifications:

• Product Line: SX35 (Standard Shaft Variant)

• Thrust Power (at 10.5V Nominal): 35 kg (77 lbs)

• Thrust Power (at 12V Peak): 43 kg (95 lbs)

• Motor Output (at 10.5V): 1.8 kW (2.4 HP)

• Typical Vessel Size Class: Up to 32 Feet (9.5 meters)

• System Voltage: 12V DC

• Max Transom/Hull Thickness: Up to 50 mm (1.96'')

• Internal Tunnel Diameter: 140 mm (5.51'')

• Recommended Fuse Size: ANL 150

• Net Weight: 15.3 kg (33.7 lbs)

• Propulsion System: Single 5-Blade Q-Prop™

• Control Signaling Type: Analog Plug-and-Go

Pro Tip: For vessels experiencing heavy water-flow friction at cruising speeds, or for sailboats looking to minimize drag to zero, the SX35 can be retrofitted with an optional Hydropod low-drag cowl kit. This seamlessly covers the pod assembly to ensure smooth hydrodynamic tracking while under way.

SLEIPNER SRV80/185T VERTICAL RETRACTING THRUSTER | 24V ON-OFF | 80KG/176LB | SRV80/185T-24V

Take the stress out of tight dockings without compromising your hull's hydrodynamic efficiency. The Sleipner Side-Power SRV80 (SRV80/185T-24V) is a heavy-duty, vertically retracting 24V on-off thruster engineered for performance sailboats, shallow-draft motor yachts, and vessels between 35 and 48 feet. Delivering a dependable 80 kg (176 lbs) of lateral thrust, this unit deploys straight down to pivot your bow or stern, then pulls completely flush into the hull when underway for zero cruising drag.

This model features a flange-mounted configuration where the core thruster and motor assembly are securely enclosed in a bolt-down casing. It is an exceptional solution for series boat production or direct replacement applications.

(Note: This SKU contains the vertical mechanical thruster unit, actuator, and 24V motor assembly; it does not include the installation outer frame or mold-in flange base).

Key Features:

• Vertical Retraction Mechanism: Drops straight down to maximize deep-water leverage when maneuvering, and retracts straight up flush with the hull to preserve your boat's raw speed and fuel efficiency.

• 80 kg (176 lbs) of Pushing Power: Provides robust, reliable docking assistance to easily pivot your vessel against stubborn crosscurrents or tight marina slips.

• High-Efficiency 24V Architecture: Runs cooler, draws fewer amps, and allows for smaller, lighter cable routing compared to traditional 12V models—making it ideal for modern 24V yacht electrical grids.

• Deep Waterline Leverage: Because a retractable thruster deploys deeper under the waterline than a traditional fixed tunnel thruster, it avoids drawing in surface air (cavitation), resulting in greater efficiency and whisper-quiet operation.

• Twin Q-Prop™ Counter-Rotating Propellers: Outfitted with aerodynamically skewed composite twin propellers that maximize thrust output while reducing cabin noise and vibration by up to 75%.

• Intelligent Power Control (IPC): Sleipner’s patented smart monitoring firmware protects your solenoids and mechanical gears by preventing damaging, instantaneous direction changes.

Specifications:

Pro Tip: The SR80 24V model is highly recommended for modern yachts with dedicated 24V house or thruster banks. The lower current draw means significantly less voltage drop over long cable runs from the battery bank to the bow or stern compartment, ensuring full rated power when you need it most.

SLEIPNER SX80/185T-12V EXTERNAL STERN THRUSTER | 12V | TWIN PROPS | 176-212LB THRUST

The perfect external stern thruster solution for boats with restricted internal space, shallow drafts, or standard 12V house battery banks. The Sleipner Side-Power SX80/185T-12V is a self-contained, externally mounted pod thruster designed for vessels from 35 to 48 feet. By mounting directly to the outside of the transom, the SX80 eliminates the need for extensive internal hull tunneling, complex fiberglass work, or engine room re-routing, making it an absolute favorite for quick retrofits and modern, space-limited builds running on a standard 12V electrical system.

The SX80 generates a reliable 176 lbs (80 kg) of thrust at a 10.5V nominal load, ramping all the way up to 212 lbs (96 kg) of thrust under a full 12V peak load to seamlessly square your stern up against tricky crosscurrents and heavy dockside winds.

Key Features:

• Hydrodynamic, Space-Saving External Pod: Positioned entirely outside the hull on the transom, the SX80 frees up vital internal storage and engine room volume. Its hydrodynamic casing ensures negligible drag and zero impact on sailing or cruising performance when under way.

• Patented Intelligent Power Control (IPC): Sleipner's advanced microprocessor-controlled system protects your thruster from mechanical wear and operator error. It enforces a minimal safety delay when switching drive directions, monitors solenoid function, and automatically halts the thruster in the rare event of a solenoid lock-in.

• Twin Counter-Rotating Q-Prop™ Propellers: Outfitted with dual, 5-blade composite skew propellers spinning in opposite directions. This twin-prop configuration packs maximum thrust density into a narrow 185mm (7.3") integrated tunnel while dropping noise and cavitation vibrations by up to 75%.

• Ignition Protected (ISO 8846) & Hermetically Sealed: Structurally sealed to meet rigorous ignition protection standards, making it completely safe for installation on the sterns of gasoline-powered vessels, near fuel ventilation paths, or in harsh saltwater environments.
