The electric motor produces a very similar propulsive figure to the combustion motor, however it uses the energy in a much more effective manner.

    Having used the outboard over a couple of weeks and clocked up about 10 hours running in varying conditions from flat calm to heavy Atlantic swell, I am very pleased with it.
    As anticipated, I had to alter the outboard well on my Drascombe Scaffie to provide more clearance but it was well worth the effort and the extra short shaft length is absolutely spot on.
    Part of the delight is creeping up silently on wild life at “tick-over” rather than scaring them off with a noisy motor and my daughter has likened the whole process to ” sailing without the sails up ” [ how’s that for an advertising slogan ?].
    Life is altogether much more serene…….
    Thank you for your support and feel free to convey this along the line.
    Kind regards,

    I have been playing with the eprop all weekend and am a little bit in love.

    Here are some observations:

    – it’s definitely faster than the torqeedo (at least the 1003 I had). We get an extra half knot at half power and a whole extra knot at full power. This may be to do with it being more effective for heavier loads, Amélie weighs around 700kg. No longer am I holding up faster boats that are behind me when I leave the lock. We can get under way at a very respectable 4.2knots (where the torqeedo topped out at 3.6).

    – it’s more responsive than the torqeedo. I don’t know if this is because of the gearbox thing, but the power is seemingly instant, which if you’re dodging a racing dinghy that’s been blown off course (as we can be) is a real bonus.

    – I won’t go on about the noise differences as you know all about that, but for us we found it on occasion virtually silent. There were a couple of instances when we were sailing upwind and didn’t even realise it was still going !! Wondered how we hit 6knots (which is rare on Amélie).

    – battery is good! On a 7nm trip both days we used half the battery. This was a combination of motoring, sailing & motor-sailing. At least half the time it was running.

    – it punches the tide !! The torqeedo simply couldn’t manage this. At full power we’d get 1.5 knots in light airs but if we were heading to windward in any breeze that fell virtually to zero. Eprop not only punched 1.5 knot tide at a respectable 1.8knots at half power, that was into a 10 knot breeze.

    – it’a more manoeuvrable! I think the responsiveness really assists this, but coming in and out of my berth is far easier with it because you aren’t having to second guess when the power will arrive. 90watts in reverse will see us beautiful ease backwards out of the berth like a dream.

    – the battery may be heavier but the bag is better! Because it’a a backpack it’s far easier to carry despite the extra weight. Seems a better quality too.

    So in summary I’m pretty pleased and glad I went for it.

    Hi Rick,

    Just thought I’d drop you a note to let you know how pleased we have been with the Epropulsion Spirit outboard you sold to us at the Beale Park Boat Show. It has been a fanstastic change for us to have the calm and quietness of the electric engine on the River Thames over the summer. The performance has been pretty good, we can get the boat (a Drascombe Lugger) just about up to hull speed but at 3kn or so (the max speed on the ariver is 4kn) we comfortably get between 4 & 5 hours powere although to be honest we mostly only go out for between 3-4 and that probably includes a lunch or sundown drinks anchor up/bank tie up or a swimming dip so we have not really tested the engine to ‘Max’.

    Apart from the quietness, The simplicity of the engine in terms of starting, re-starting, gear changing has given Erica much more confidence to take the boat out on her own (she never quite mastered the petrol outboard) or with her own friends . The other real advantage is that once we take the battery off the leg is so light we always take it off the transom and stow below – there are many instances of outboards being stolen on the River (and we had a 5hp Tohatsu stolen off our Drsacombe Coaster when it was at Bucklers Hard) – so it has given us some significant extra piece of mind.

    Hope you are all well, the engine has generated a lot of interest from other River users who all can’t quite believe how quiet it is. I hope your sales may have reflected some if this interest.
