Side-Power SXP Electric External Stern Thruster 12V — 80kg, Sealed 5-Blade

The SXP External Stern Thruster delivers up to 80 kg (176 lb) of thrust, providing powerful and reliable maneuverability for yachts and motorboats. Designed as an electric stern thruster, it is easy to install externally on the hull, making it an ideal retrofit solution when internal space is limited.

Featuring a sealed 5-blade propeller system, this thruster ensures quiet operation, smooth water flow, and long-term durability. Whether you’re docking in a tight marina or maneuvering in crosswinds, the SXP gives you the confidence to take full control of your vessel.

Yacht Stern Thruster

Yacht owners often face challenges when docking in narrow slips or handling strong currents. The SXP yacht stern thruster provides:

• Precision control for side movements and tight turns.
• Low-vibration performance with its hydrodynamic 5-blade propeller.
• Electric operation, eliminating the need for hydraulic systems.
• Durability with sealed housing for protection against water ingress.

This makes it an excellent option for yacht refits or new builds that require high thrust in a compact design.

External Mount Stern Thruster

Unlike traditional tunnel thrusters, the external mount stern thruster is installed directly on the transom or hull exterior. Advantages include:

• No need for tunnel drilling—simplifies installation, especially on finished boats.
• Retrofit-friendly solution for yachts and motorboats without internal space.
• Minimal hull disruption, since it mounts externally.
• Efficient thrust positioning for stern-side control.

This makes the SXP system particularly attractive for owners seeking a thruster upgrade without major modifications to their vessel.

Key Features

• 80 kg (176 lb) thrust output: strong performance for mid-size vessels.
• Sealed 5-blade propeller: optimized for noise reduction and efficiency.
• Electric drive system: efficient, clean power with 12/24V compatibility.
• External mounting: retrofit-friendly, avoids complex tunnel installations.
• Durable sealed housing: protects motor and components for long service life.
• Compact design: suitable for yachts and powerboats with limited space.

Performance in Real-World Conditions

The SXP 80kg electric stern thruster is built to handle demanding marine conditions:

• Crosswinds in marinas: Provides instant corrective thrust for stable docking.
• Strong currents: Helps maintain control when navigating narrow canals or rivers.
• Solo docking: With joystick integration, captains can dock confidently without full crew assistance.
• Tight maneuvering: Allows precise positioning when rafting alongside other boats.

By translating raw thrust into smooth handling, it ensures safety and control in real-world environments.

Maintenance & Durability

This thruster is engineered for long service life with minimal maintenance:

• Sealed gear housing prevents water ingress and protects internal components.
• Composite 5-blade propeller reduces wear, vibration, and noise.
• Corrosion-resistant design with zinc anodes for saltwater protection.
• Low-maintenance operation, making it ideal for yacht owners seeking reliability without frequent servicing.

Comparison – External vs Tunnel Stern Thrusters

The external mount stern thruster offers the best compromise for yachts that lack tunnel space but need reliable maneuvering power.
