Side-Power eVision Electric Tunnel Thruster (Bow/Stern, 24/48V)

eVision Tunnel Bow/Stern Thruster

The eVision is a highly efficient, compact, lightweight thruster suitable for boats. The integrated inverter for variable speed control makes for a quick and easy installation.

eVision has the new 6-phase PMSM synchronous motor made explicitly for marine thruster use, delivering performance and runtime never seen before in a DC thruster.

• Up to 50% lighter
• Compact design
• Industry-leading runtime
• Active air cooling

Properties

S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel.

• Compact and waterproof plugs
• Keyed and color-coded connectors to ensure correct and easy installation
• Different cable lengths, extenders and T-connectors makes the system scalable and flexible to install

The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power.

• The expected noise reduction in average installations: 20-40%
• Upgrade kits are available for most Sleipner thruster models with special adaptors

A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.

The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks – making docking truly a one-person job.

Speed controlled thrusters are the best choice for joystick interaction.​

Our ignition-protected products are compliant with ISO 8846 and ensure gasoline or other flammable fumes cannot enter or be ignited.

When an unsafe temperature is detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating the thrust power to maintain temperature within safe levels.

Sleipner offers installation flexibility to work with the space you have. Our thruster models allow installation at any angle on the tunnel, tailored to fit any space available in your vessel.

This product is manufactured for installations in environments that may experience moist or occasional splashes.

Powered by direct current.

Immersed parts exposed to seawater are galvanic isolated from the onboard electrical system, eliminating stray currents.

The thruster gearleg is pre-filled for lifetime lubrication and sealed using a long-time mechanical seal with ceramic and carbon surfaces for ultimate security against water intrusion.

Flexible coupling protects the product’s driveline by compensating for misalignment between the shafts of the electric motor and gearleg.

Two counter-rotating propellers offer the most thrust at a good performance ratio in a minimal tunnel diameter. This system is used in our larger thrusters for maximum power. Our twin-counter thruster range is the favorite among leading boatbuilders in high-end yachts.

Bow Thruster Electric Motor

The heart of the eVision system is its bow thruster electric motor, a 6-phase PMSM synchronous motor specifically engineered for thruster applications.

• Provides industry-leading runtime

• Variable speed control eliminates the harsh noise of on/off thrusters

• Active air cooling ensures safe extended operation

• Maintenance-free sealed lubrication system protects against water ingress

Overheat Protection

• On/off thrusters: automatic shutoff at unsafe temperatures

• PRO™ thrusters: reduced thrust to maintain safe operating temperatures

Operational Use

These specs confirm the eVision’s suitability for both bow and stern tunnel installations in mid-sized yachts.

Certifications

The eVision thruster is built to comply with marine safety standards worldwide.

Certified for international use, ensuring compliance with European and UK regulations.

Dimensions & Weight

The eVision’s compact and lightweight design makes it easier to install compared to other thrusters of similar power.

These dimensions make the eVision compact enough for vessels with limited hull space, while still offering strong thrust output.

Stern Measurements

These measurements apply when mounting in the stern, offering flexibility for yachts with varied hull designs.

Additional Technical Features

• Splash-proof: suitable for moist or splash-prone environments.

• Sealed drive lubrication: lifetime oil-filled gearleg.

• Twin counter-rotating propellers: used in larger models for maximum thrust in minimal tunnel diameter.
