Epropulsion Spirit 1.0 Plus Electric Outboards

Click here for details

The Spirit 1.0 Plus is the industry leading portable electric outboard motor. Leading the way in performance rechargeable outboard motors, it is a highly reliable and affordable step to greener boating.

Why is an electric outboard better?

• 1kW offers equivalent power to a 3hp engine
• clean, quiet, less harm to nature & the oceans
• extensive motoring range & capacity
• up to 5 hours / 22 miles in 3m tender
• maintenance free – no fuel or oil on board

This lightweight, highly portable outboard motor can be recharged using 12 volt output or solar power.             
It has an unsinkable battery that is recyclable.

Reliable, flexible boating

Like all the innovative ePropulsion motors the Spirit 1.0 Plus is built to last. The motor passed a continuous 83 day run test, with flying colours.

It’s easy to carry and store on board, by separating the battery from the shaft, making it perfect for:

• 
  
  
  • yacht tenders
  • SIBs (small inflatable RIBs)
  • day sailing boats & dinghies
  • small motor boats and day boats
  • fishing boats
  
  
  

Portable electric outboard efficiency

The 1276Wh battery means 75 minutes run time at full throttle compared to 45 minutes for an average 3.5hp petrol outboard at full power.

The highly efficient battery means more reliable boating and more effective boating.

All ePropulsion’s electric outboards use a direct drive motor which has considerably more torque than a motor using gears. It is more efficient than a combustion engine, and it conserves overall use of power.

With few moving parts and no fuel, oil or grease needed, you’ll save money too as there is no maintenance, winterising or servicing required.
