The Spirit 1.0 Plus/Evo and RemigoOne are both 1kW motors (about 3HP). Can I go twice as fast as my 500W (1.5HP) eLite?

Perhaps somewhat surprisingly, no. Water drag increases exponentially with speed. To go faster, your motor has to push harder against resistance. In practical terms, doubling speed requires roughly four times the power. So a 1 kW motor will get you faster, but only about 30% faster—nowhere near twice as fast.

However, your ride with a Spirit 1.0 Plus / Evo or RemigoOne will feel faster than the eLite. You’ll notice stronger acceleration and a higher top speed (but don’t expect to double your speed). Think of it as moving from a bicycle to an e-bike—not a car. The upgrade is about power, range, and handling, not raw speed.

What you DO get when upgrading from an eLite to a larger 1kW outboard motor is:

• Higher top speed: Around 30% faster than the eLite.
• Much greater thrust: Helps against current, waves, and wind.
• Better efficiency at cruising speeds: A 1 kW motor running at half power (≈500 W) is usually quieter and more efficient than a smaller motor pushed to its maximum.
• Longer range with larger batteries: The Spirit 1.0 Plus/Evo comes with a 1276 Wh battery (about 3× the capacity of the eLite’s 378 Wh pack).
