Andrew, isn't that pod thing you bought perfect for the job? OK it's supposed to be bolted to the hull of something but adapting it to an outboard-style setup would be a piece of cake.

No UK distributor though. I bought it from a geyser who used to be UK distributor but he is now retired. Price from EU is about twice what I paid for it. Intermotor is the brand.

I haven't tried it but I think a 3 way switch to run on 12,24 or 36v would be lovely for one of the Minn Kota. They are fine on 12v if a bit slow. Straight onto 36v is a bit heavy on the mounting hardware. 4QD PWM controller would be the ideal thing but not cheap.
I have an el cheapo Chinese PWM controller remotely controlling my 12V 40lb MK trolling motor, with a 100A circuit breaker in the battery supply lead. The motor draws about 35A but whenever I have run on full power against a stiff wind I found by experience that anything less than a 100A breaker and a 100A fan-cooled PWM will cut out or burn out respectively. The breaker is effectively a thermal cut-out and even at 100A with fan cooling it sometimes cuts out on a long run in summer (no problem this year then).
Coincidentally I am planning to buy an eProp 1.0 which has a 1.3kwh battery one of these days and cut down my 12V battery bank by 50% to save weight - the batteries will provide power for the MK as a standby motor plus power for the boat's lighting and USB sockets.

paulhd I should correct myself I didn't mean a 36lb thrust motor I meant a 36 VOLT minn Kota motor. They are more like 100lb thrust. Example Riptide 101. DIY job for that they are about £350 from USA. I did find a UK supplier but forgot where. A little 36lb won't do much on that sort of boat. Sorry for the error. Yes the Epropulsion remote throttles look really good. Big investment but it would be well worth it for a boat like that I reckon. I spoke to someone not long ago about the Epropulsion he was going to be getting a container load of them quite soon. Not sure which company he was. It was a call back from an online enquiry. Will see if I can find out. It was Epropulsion UK I spoke to. epropulsion.uk/epropulsion-electric-outboards/I think they sell them but not sure, they might go out to dealers. Cheers Andrew, I have just sent an email off to epropulsion to see if they have anything in stock. I have tried getting in touch with a place called Nestaway, but not had any reply. They are a little bit thin on the ground at the moment. I have definitely decided not to go with the pod idea even though that would be a fantastic solution. I will go with traditional outboard looking design, as I will be able to share with the Wayfarer and possibly the Mirror. 👍

They look good these epropulsion units.
The one I would really like is the old Accumot but they are all on the continent I don't think they ever came over here with them.
Nice durable units. The aquamot I have is more or less the same thing but the old Accumot worked on a solid state switch rather than an electronic speed controller so probably more reliable.
I slightly dislike the look of the torqeedo and Epropulsion but they are popular. I reckon the latter is better quality but have not tried either of them.
As for torqeedo they have recently introduced a direct drive version of their small outboard which take out the annoying whine you get on the original ones.
Torqeedo 1003 is their direct drive unit.

The epropulsion have an extension cable so the battery can be off the outboard or plugged into a different battery source. Which would make the motor part a very light 10 odd kilos. I think I have that right but I could be wrong, I have been reading so much about these things it is giving me a headache😃

However something with a remote battery would be good for weight distribution.

Yamaha and Honda might be better but not much quieter. for that you need a twin and it's going to be much much heavier. The Epropulsion is the right approach I reckon.

Heavy? not eProp 1.0; including the battery it is only about 19kg. - m probably less weight than those 6-packs of beer that are a compulsory accessory.

I like the fact Epropulsion have floating batteries. Good idea.
Another approach might be to have a pair of smaller motors. Minn Kota did a dual motor mounting bracket which was quite interesting.
It would probably be feasible to put two electric pods on the boat and leave the 4 stroke outboard in place. That would be nice !
Would involve some hull modifications though which I don't think the OP wanted.

Looking a the photo of the Drascombe I reckon the approach I used on the febdp would work.
Minn Kota outboard(s) top chopped off and shaft mounted using a Stauff clamp which bolts to a stainless steel hinge. the hinge can then be bolted to any suitable surface. piece of rubber as a thrust bearing.
Simple no-nonsense low profile option for mounting trolling motors without buggering the boat up.
I'll put a picture up later.
It was a bodge but remarkably effective and allows easy stowage. Looking at the slope of the wooden board I think something very nice could be done there with a pair of trolling motors which slide up out of water when not in use.

bodger have you considered one of the water snake units? They look very interesting to me. A bit tempted by one of these for the floating electric beer drinking platform but I would have to cut it in half as I need the control to be remote from the motor so it would be a bit naughty doing that with a new £370 unit.
problem is that AFAIK all "trolling motors" are engineered to do 5mph max, and in practice 3.5mph is all I have ever seen on my canoe-shaped 6 metre boat whereas I would expect anything up to 6mph with the eProp, with the penalty of shorter range but, as you know, when punching up Henley Reach against wind and current really takes some effort for a marginally powered boat, in fact I have sat still at full power for minutes at a time, taking as long as 3 hrs from Hambleden to Marsh leaving the batteries nearly flat and barely able to make Shiplake charging point.
you may recall I posted on a different thread about my experiments with the MK 40 in a circular paddling pool with various different props fitted. The airscrew and the aftermarket 3 bladed props showed no improvement in thrust or speed. Typical American engineering - they have got it just right with their weedless wedge 2 blade and see no reason to change.
