ePropulsion Spirit 1.0

The Spirit 1.0 is ePropulsion’s portable 1 kW electric outboard, which the maker compares with a 3 hp petrol engine: a brushless direct-drive motor with a floating lithium battery that locks onto its top, found on tenders, inflatables and small fishing boats and as an auxiliary on small sailing boats. The first version ran at 40 V with a 1018 Wh battery; in 2020 the Spirit 1.0 Plus replaced it, with 48 V, a 1276 Wh battery in the same case, a metal power connector and the option of an external battery. The Spirit 1.0 Evo (from 2021) adds a detachable tiller or remote controls and hydrogeneration, which recharges the battery through the propeller under sail; Plus and Evo are still sold next to the Spirit 2 of 2026, a different motor not covered here. With no oil, impeller, spark plug or gearbox, owner service comes down to propeller and shear pin, anodes, a few grease points, the connectors and battery care.

Wear parts & part numbers

Part	OEM number	Also fits	Note
Propeller	`S1-M001-00`^1,2,3	—	11 × 5.8 in, 2-blade composite. ePropulsion lists it for the Plus (XS/S/L) and the Evo (S/L); the first-generation manual gives the same size, but the maker’s fitment list does not name that motor. EMO Electric sells it with shear pin, washers and nylon locknut.
Shear pin	`04-0103-25`⁴	—	Plus and Evo, all shaft lengths. Check it every time you look at the propeller.
Propeller anode	`SP-M012-00`^5,6,7	—	Shaft anode, screwed onto the propeller nut with an M5 screw and spring washer. Plus and Evo; EMO Electric also packs it in its set for pre-2022 motors, but the first-generation manual shows no anode at the propeller.
Anode (lower unit)	`SP-M013-00`^8,9,7	—	Motor anode under the anti-ventilation plate. Plus and Evo; EMO Electric also includes it in its set for the first generation and pre-2022 Plus.
Anode (clamp bracket)	`SE-TB01-00`^10,6	—	Clamp anode, Evo type: for the Plus built from 2022 and every Evo.
Anode (clamp bracket)	`S1-TB03-06`^11,9,7	—	Trapezoidal clamp anode, two per motor according to EMO Electric: first generation and Plus built before 2022, in place of the Evo clamp anode. ePropulsion’s parts page gives no fitment list.
Anode (clamp bracket)	`S1-TB02-05`^12,6,9	—	Clamp base anode. ePropulsion lists it for the Plus (XS/S/L); EMO Electric puts it in both anode sets, for older and for 2022-on motors.
Battery	`SP-B000-02`^13,14	—	Spirit Battery Plus, 1276 Wh / 48 V, for Plus and Evo, including the Evo Remote. It does not fit the first-generation 40 V motor, and the old 1018 Wh battery does not fit Plus or Evo.
Charger	`SP-C001-01`^15,16,17replaces SP-C001-00	—	Standard 180 W charger supplied with the motor: 100–264 V AC in, 52.2 V / 3.5 A out, about 8.5 h from empty. For the Battery Plus only, not for the first-generation battery.
Charger	`SP-C004-02`^18,19,16	—	Fast charger, 520 W, for the Battery Plus: about 3 h from empty according to the parts page (the manual says 3.5 h). ePropulsion gives 100–240 V AC input; Blue Marine lists a 120 V version under the same number.
Charger	`SP-C002-00`^20,21	—	12/24 V DC charger, 70 W: charges the Battery Plus from a 10–30 V supply on board.
Charger	`SP-C003-01`^22,23	—	12 V / solar charger 2024 (MPPT charge controller) for the Battery Plus, panel not included. The earlier 180 W solar charger is SP-C003-00; ePropulsion does not say that one replaces the other.
Emergency stop switch & lanyard	`S1-TH02-00`^24,25,26	—	Magnetic kill switch with lanyard for the Plus tiller and the Evo Tiller (which comes with two). The Evo Side Mount Control takes SM-TH03-00, the Evo Dual Remote Control NE-DR02-00.
Tiller / remote	`NE-TC00-00`²⁶	—	Evo Tiller: detachable, with display, for the Evo (also the Navy 3.0/6.0 Evo); comes with two kill switches S1-TH02-00. Not for the Plus, whose tiller is built in.
Tiller / remote	`NE-TC01-L0`^27,28	—	Tiller extension, 60 cm (“EVO/Plus Tiller Extensions”). ePropulsion names the Evo Tiller as fitment; Blue Marine lists it for Plus and Evo.
Remote control	`NE-RC00-00`²⁹	—	Evo Remote Control: wireless top-mount control with display for the Evo Remote (1.0R Evo); comes with a kill switch S1-TH02-00.
Remote control	`NE-SM00-00`^30,31,32	—	Evo Side Mount Control with display, for the Evo. The newer Smart Side Mount Control Evo is SE-SM00-00; twin installations use the Evo Dual Remote Control NE-DR00-00.
Remote control	`SE-R999-00`³³	—	Spirit 1.0 Evo Remote Kit, for the Evo with short or long shaft; ePropulsion links it to the technical drawing of the Evo Remote.
Cable	`00-0601-01`^34,35,30	—	Communication cable, 5 m: links an Evo motor to an Evo control or an E-Series battery (with E-Series batteries it is needed for hydrogeneration). The Evo Side Mount Control comes with the 0.5 m version, 00-0601-04.
Power cable	`00-0601-08`³⁶	—	External battery cable, 1.5 m, to a 48 V E-Series battery. Plus and Evo only; ePropulsion says it does not work with the first-generation 40 V motor.
Power cable	`00-0601-09`^37,38	—	Extension power cable, 2 m, between the Battery Plus and the motor; Plus and Evo.
Motor cover	`SP-M005-00`^39,40	—	Cowling that goes on top of the motor in place of the Spirit battery when it runs on an external E-Series battery; Plus and Evo.
Power socket & plug	`S1-BA01-00`^41,42	—	Battery power output set: a T connector that takes 40 V (first-generation battery) or 48 V (Battery Plus) off the battery for other devices, and an activator that shows the battery voltage and wakes the battery. Its manual says it suits both batteries.
Anti-cavitation plate	`S1-AP00-00`⁴³	—	Anti-cavitation plate above the propeller; fits Spirit 1.0 Plus and Evo per ePropulsion’s parts database.

Service intervals

Task	Interval
Propeller	Every 50 h or every 3 months¹⁶
Anode	Every 50 h or every 3 months¹⁶
Lubrication	Every 100 h or every 6 months¹⁶
Full service	Dealer check every 200 h or yearly: propeller and shear pin, anodes and grease points, replacing parts as needed¹⁶
Electrical connections	Clean the power and communication plugs with contact cleaner every 2 months, and at once if corrosion shows; the safety notes also call for contact spray about every 3 months¹⁶
Fresh-water wash	After every use in salt water, rinse the whole motor with fresh water; tilt it out of the water after use¹⁶
Battery charging & storage	Store at about 60 % charge, dry, at 15–25 °C; every 3 months charge it back to about 60 %, and charge it fully before use. Recharge straight after a full discharge and never run it below 33 V¹⁶
Storage / winterising	For more than 2 months: clean and check the motor, then store it dry and ventilated, out of direct sun, ideally in its original packaging and with no load on the propeller³⁵

Hours or months, whichever comes first. The schedule is from ePropulsion’s Spirit 1.0 Plus user manual (V2.9, 2025): the owner checks propeller, shear pin and anodes and greases the clamp and tilt bracket, and a dealer does the 200-hour or yearly check. The storage rule is from the Spirit 1.0 Evo user manual (V1.5, 2025).

Good to know

Lay the battery up at about 60 % in a dry place at 15–25 °C and recharge it every three months; ePropulsion stresses this point. A battery left flat for a long time goes into sleep mode and only wakes up on the charger, so never store it empty.¹⁶
Carry a spare shear pin (04-0103-25) and a 17 mm socket. Disconnect the battery first; on Plus and Evo take out the anode screw on the nut, then the 17 mm locknut and the disc spring. Put it back together in this order: washer, shear pin, propeller, disc spring, locknut, anode.^16,4
After salt water, rinse the whole motor with fresh water and tilt it clear. The anodes are the main wear part: check them every few months and order the right set, because the first generation and Plus motors built before 2022 use two trapezoidal clamp anodes, while 2022-on Plus and every Evo use the Evo clamp anode.^9,10,16
Keep the plugs clean and dry: contact spray every few months, caps on every port not in use, and on the Evo a cap on the communication socket whenever no cable is plugged in, or it corrodes and the motor loses its link to the control. The metal power plug on Plus and Evo only needs hand-tightening, about half a turn.³⁵
Batteries and chargers do not swap between the first-generation 40 V Spirit 1.0 and the 48 V Plus and Evo, and only Plus and Evo can run on an external E-Series battery. When you buy a used motor or a spare battery, check the generation: the model name is on the tiller, and the battery label reads either 1018 Wh / 40.7 V or 1276 Wh.^44,13,36
If the display shows E30 (throttle position sensor), recalibrate the throttle as the Evo manual describes before you suspect a fault; E10 usually means something is wrapped around the propeller. The manuals describe no firmware update by the owner, so software problems go to an ePropulsion dealer.³⁵
