Yachting Monthly magazine Best Buy’

Get ahead with the industry leading Spirit 1.0 Plus portable electric outboard motor. This hugely popular performance, rechargeable outboard motor 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. And, it has been voted ‘Best Buy’ in a Yachting Monthly test of 12 electric outboards!

Easy to carry and store on board, the battery separates from the propellor shaft, which makes 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.

It’s 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. Because it is more efficient than a combustion engine 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.

Range – how far can you go with an electric outboard?

Range in a 3m tender

Spirit 1.0 Plus has a 1276Wh integrated battery. At full throttle (1000 watts), you get 6.2 mph for 75 minutes. The range is 7.75 miles.

At a reduced throttle speed,  25% of maximum uses 250 Watts. You will get 4.4 mph for 5 hours with a range of 22 miles.
