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

The ePropulsion Spirit 1.0 Plus is a portable 3 HP-equivalent (1000 W) electric outboard built for dinghies, tenders, day-sailers, and small fishing boats. It delivers clean, quiet, fume-free power with the convenience of one-button electric start and an intuitive tiller. Its modular design splits into manageable parts for easy carrying and stowage, making it a low-maintenance alternative to a small gas outboard for boaters of every skill level.

Powered by an optional 1276 Wh lithium battery (sold separately), the Spirit 1.0 Plus pairs strong range with peace of mind: the lightweight 19 lb (8.7 kg) battery is fully integrated and floats if it is ever dropped overboard.

Key Features

• 3 HP-class electric power — 1000 W of quiet, instant thrust for tenders, dinghies, and light sailboats.
• One-button electric start — no pull cords; smooth, stepless throttle with adjustable power settings.
• Digital display + app — see power output, remaining run-time, battery level, and speed in real time, with Bluetooth connectivity.
• Magnetic kill switch — immediate shutdown in an emergency, with two switches included.
• Floating lithium battery — 1276 Wh, just 19 lb (8.7 kg), and floats if dropped in the water (sold separately).
• Child & rental safety + ambidextrous design — limit maximum power and operate comfortably with either hand.

What's included: Spirit 1.0 Plus motor & shaft, tiller, two kill switches, battery charger, and mounting pins. Battery is not included and is 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. Using ePropulsion's own recommendations: an Extra-Short (XS) shaft suits transoms of about 11.8–15.7 in (300–400 mm); a Short (S) shaft suits transoms of about 15.7–19.7 in (400–500 mm); a Long (L) shaft suits transoms over 19.7 in (500 mm).

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).
