ePropulsion Spirit 1.0 Evo Electric Outboard Motor (3 HP, 1000 W)

The ePropulsion Spirit 1.0 Evo is a 3 HP-equivalent (1000 W) electric outboard built for dinghies, tenders, day-sailers, and small fishing boats. It delivers quiet, fume-free propulsion with a genuinely premium feel — and adds hydrogeneration, so the motor can recharge its battery while you sail or tow. It is a clean, low-maintenance alternative to a small gas outboard.

Key Features

• 3 HP-class electric power — 1000 W of quiet, instant thrust for tenders, dinghies, and light sailboats.
• Hydrogeneration — recovers energy and recharges the battery while sailing or under tow.
• Bluetooth app + tiller readout — see battery level, speed, and remaining range in real time.
• Lightweight & portable — splits into manageable parts for easy carrying, mounting, and stowage.
• Modular controls — works with side-mount, top-mount, and dual-control options (sold separately).
• Battery: pairs with the ePropulsion Spirit Battery Plus (1276 Wh, sold separately).

Battery and control options are not included and are purchased separately.

How to Measure Your Transom Height & Choose Your Shaft Length

Picking the right shaft length is the single most important fitment decision on any outboard. It comes down to your boat's transom height — if the shaft is too short the propeller ventilates (sucks air) and loses thrust; too long and it adds unnecessary drag.

1. Measure your transom height. With the boat level, measure straight down from the top of the transom (where the motor clamps) to the bottom of the hull at the centerline.

2. Match it to the shaft length. As a general guide: a Short (S) shaft suits transoms up to about 15 in (38 cm); a Long (L) shaft suits transoms up to about 20 in (51 cm).

3. When you're between sizes, size up. A slightly long shaft runs fine; a too-short shaft will cavitate.

ePropulsion's own method adds the propeller radius (~5.5 in / 14 cm) and ~4 in (10 cm) of water-flow clearance to your transom height to get the total shaft length needed. Example: a 21 in transom + 5.5 + 4 ≈ 30.5 in, which points to the Long shaft (29.5 in).
