Title: Electric outboards.
Post by: cgadeney on October 16, 2021, 08:29:34 AM
I am hoping to buy a Winkle Brig. A the moment I use an Epropulsion Spirit plus on my current boat on inland waters. Does anyone know if this will fit on a WB and how it performs?

Sorry, no idea if an Epropulsion fits, but a Torqeedo 1103 short shaft definitely fits, although only just and with the mounting bracket raised up about 110mm. There are detailed drawings and dimensions of the 1103 on the Torqeedo website, so you may be able to compare with the Epropulsion and see if it is compatible.

I see on YouTube there is a video about WB 18, Sea Jade, in Cornwall 2021 and the description mentions it is equipped with an Epropulsion motor.

We love the Epropulsion motor, it?s a Spirit Plus Evo so  charges itself if you?re doing anything over 4.3 knots.

There?s loads of torque from this unit so it?ll punch along through some big seas and tide really well. It?s ideal for a displacement hull I?d say.

We haven?t measured things scientifically but, this summer we motored all the way from the Helford passage to Mylor at about 2.5 knots (around 9nm) and we still had about 20% left in the battery when we arrived.

At full power I think we can hit 4.5 knots but this will only give 75 mins runtime. Half power gives about 3 knots speed and perhaps three hours runtime.

We?re going to get a second battery next year but for a backup this year we had a Lifos 12v battery and solar panel. We never ran out of power but you do need to think about how you use it.

As for fitting, the motor sits in the outboard well perfectly but the battery is too big so you?ll need to put this in the rear locker and use a dedicated extension cable.
The short shaft is the right length for the boat but does protrude beneath the skeg by about 80mm so is a little vulnerable in the shallows.

To sum up, the ease of use is fantastic. I?d recommend it and say that the power is adequate. The range though might be an issue with just one battery in a strong tide / if there?s an emergency etc.
