SLEIPNER KIT: SXP50 EXTERNAL PRO THRUSTER | 12V PROPORTIONAL | 50KG/110LB THRUST | FITS UP TO 50MM TRANSOMS | SXP50-50MM-2

The world’s most compact external thruster, designed for standard hull profiles, limited bilge space, and absolute throttle precision. The Sleipner Side-Power SXP50 Kit (SXP50-50MM-2) is a specialized, 12V proportional external thruster engineered for boats from 27 to 37 feet where a traditional internal tunnel installation is physically impossible. This high-performance kit delivers a robust 50 kg (110 lbs) of lateral thrust and features a mounting configuration specifically optimized to bolt securely through transom or hull sections up to 50 mm (2 inches) in thickness.

Equipped with factory-standard S-Link™ Proportional Control (complete with the PPC520 DC speed controller), this system replaces crude, full-blast "on/off" switches with smooth, variable-speed throttle command. The unique "Hold" function lets you lock in a set thrust percentage, effortlessly pinning your boat safely against the dock or inside a lock while you manage mooring lines single-handedly.

Key Features:

• True Proportional Power (S-Link™): Variable speed capability gives you exact, metered power. It vastly reduces battery consumption and cabin noise by running only at the exact output percentage required.

• Standard 50mm Hull Configuration: Specifically engineered for standard single-skin fiberglass, aluminum, or steel transoms and swim platforms up to 50 mm thick, eliminating excess bolt overhang inside the bilge.

• Hermetically Sealed External Pod: The motor and internal drive are housed in a rugged, fully sealed, ignition-protected (IP) composite casing. This makes it completely waterproof and perfectly safe for installation near gasoline engines or fuel vapor zones (ISO 8846 and UL 1500 certified).

• Extended Run Times: Because the entire motor housing is completely submerged externally, it benefits from constant, highly efficient water cooling, allowing for significantly longer duty cycles per run than traditional internal thrusters.

• High-Leverage Efficiency: By mounting externally at the furthest possible point from the boat's pivot point, the SXP50 creates ideal mechanical leverage, achieving up to 40% higher efficiency than a conventional recessed internal tunnel setup.

• Pre-Installed Sacrificial Anodes: Complete with factory-installed anodes, ensuring immediate protection against galvanic corrosion right out of the box.

Specifications:

• Part Number: SXP50-50MM-2 (SXP50-12V-50MM)

• Thrust Power: 50 kg (110 lbs) at 10.5V / 62 kg (136 lbs) at 12V

• Typical Vessel Size: 27 to 37 Feet (8 to 11 meters)

• System Voltage: 12V DC

• Tunnel Inner Diameter: 140 mm (5.5'')

Pro Tip: External thrusters completely bypass the need for intensive fiberglass or gelcoat tunnel glassing work. The SXP50 configuration requires only a few precisely drilled holes for the mounting bolts and wiring harness, radically speeding up retrofit installations on standard transoms.
