The EPROPULSION Spirit is a relative newcomer to the UK market, although it has been available elsewhere for about four years now; we have been using one ourselves since April 2017. It bears some obvious resemblances in terms of specification and even appearance to the market-leading Torqeedo 1003, but also has some significant differences. Most of this page assumes you’re already familiar with the Torqeedo, but if not see: Torqeedo 1003
First the most important differences, good and bad, ePropulsion Spirit to Torqeedo 1003:
– MUCH QUIETER, The Torqeedo is quiet compared to a petrol outboard, but the Epropulsion seems noticeably quieter than the Torqeedo. This is because the Torqeedo has a small, fast-spinning motor driving the propeller through a reduction gearbox, whereas the Epropulsion has a larger, direct-drive motor (no gearbox). The Torqeedo solution is electrically more efficient; the Epropulsion mechanically more simple. The loudest part (ie what you hear) of the Torqeedo is that reduction gearbox, and it’s widely described as a “whine”. Though we have not measured it, the ePropulsion seems to be quieter (in dB terms), and what noise you do hear is a deeper “hum”. To our ears at least it’s more pleasant to listen to and generally sounds more “refined” (if there’s any wind or waves, effectively it’s silent). There is a video (not ours) of both here: Torqeedo & ePropulsion sound test
– 4kg HEAVIER. The most comparable Torqeedo 1003C (with 915Wh battery) weighs 14.9kg, the ePropulsion Spirit (1018Wh battery) weighs 18.6kg. The differences are mainly the larger capacity battery, the physically larger motor, and the fact that the eProp’s motor is housed in a metal casing rather than the Torqeedo’s (very solid and never given us any trouble) plastic one.
– FLOATING BATTERY. The E-Propulsion battery is physically larger, partly because it houses a battery with 10% more capacity (1018Wh vs 915Wh for Torqeedo), and partly because it encloses enough air for it to float if accidentally dropped. We have tried it, and it does float. The Torqeedo batteries do not float, nor are they claimed to; we have not tried that ourselves but unfortunately (for them, and their wallets!) some of our customers have… it’s an expensive mistake to make!
– FASTER CHARGE TIME. From flat, with the mains chargers supplied: the Torqeedo 915Wh battery charges in about 10 hours; the Epropulsion 1018Wh in about 5.5hrs. There is also a Fast Charger option on the Epropulsion, which reduces charge time to about 2hrs (take it to the pub with you, it will be fully recharged if you have a half-decent lunch!). Both also have the option of using 12V DC chargers.
The less significant differences:
– The Eprop’s tiller is folding rather than removable, which also means there’s only one cable to connect/disconnect (compared with the Torqeedo’s two cables). But it does mean the dismantled Torqeedo is slightly smaller to store.
– The EProp does not have GPS, so it does not have a readout for speed and range (the Torqeedo does). However both motors do tell you how much battery is left, which seems to be the bit people find most useful on the Torqeedo LCD.
– The EProp seems to be a bit slower. We haven’t yet done that much in the way of truly fair testing (identical boats, identical conditions, identical battery charge states) but so far we’d estimate this at 10%, ie the E-Prop seems to top out at 5 to 5.5 knots where the Torqeedo seems to achieve 5.5 to 6 knots.
– Only one battery option. The Torqeedo can be purchased with 532 or 915Wh batteries, the EProp only comes with a 1018Wh battery.
As the Eprop has a battery that’s 10% larger than the Torqeedo’s, but – on current best estimate – is about 10% slower (or less efficient, depending on how you look at it), roughly speaking these two factors cancel each other out. All other factors being equal, the range will therefore be about the same.
The Epropulsion is also a bit cheaper than Torqeedo’s most directly comparable model, the 1003C:
– Epropulsion Spirit 1.0kW (std shaft), 1018Wh battery, £1529
– Epropulsion Spirit 1.0kW (long shaft), 1018Wh battery, £1575
– Epropulsion Spirit spare battery 1018Wh £899
– Epropulsion Spirit spare propeller £50
– Epropulsion 12V DC and solar control charger £89*
– Epropulsion Fast Mains Charger, £250
– Epropulsion bag set(motor and battery) £149
NOTE* re 12V charger. Because of the voltage at which the Spirit battery needs to charge, this is actually quite a sophisticated DC-DC “step-up” charger and current controller, hence the additonal cost compared to the Torqeedo 12V charging cable (which is effectively a piece of cable with the right connectors on both ends). This means the Epropulsion can also be connected directly to most solar panels, ie there is no need for any extra controllers or regulators in between, and you don’t have to use any particular make of solar panel.
CHOOSING & BUYING YOUR ELECTRIC OUTBOARD MOTOR
If you contact us you will be able to speak to somebody who has actually used both the ePropulsion and the Torqeedo on the water, and can give genuine, useful (realistic!) advice about battery life, range, and whether your particular boat is suited to electric drive.
As of May 2018 we are – to the best of our knowledge – the only UK Dealer to stock both makes. By that we don’t mean “we can get one if you really want us to”; we usually have both Torqeedo and Epropulsion motors available to see and buy. There are many similarities between the two, but also some important differences. We have seen and tried both, quite extensively, and it’s only by stocking both we believe we can listen to what you want and recommend the one that will suit you better (rather than being a single brand dealer and forced into trying to sell you that one…).
We must emphasise, we have nothing against the Torqeedo 1003 – we’ve been selling them for nearly ten years, they are very good motors – but we really do feel it’s in our customers’ interests to be able to compare Torqeedo and Epropulsion directly next to each other, rather than at separate dealers perhaps 50 miles apart. If you would like to compare the two motors for yourself, we have both here, please come and see us.
