Electric outboards

Found this yesterday and seems interesting, it looks like they are releasing these in 2023 https://www.powerandmotoryacht.com/b...Ayt7cPktWJ7Qk0

It was bound to happen sooner or later, I would've thought later, but here it comes.
Not a bad idea for small tinny's/tenders. Will be interesting to see what charging they will need, if they can be charged while back on 'mother ship' or if you need serious charging power like EV's.

Looks like a
Cartridge style battery like a drill or grinder

Matt It looks basically like a Minn Kota with more fancy cowling that hides a huge cartridge type battery...

Might be fine for tenders and freshwater/impoundment boats or areas where you want to eliminate noise and fumes ..

For any more more serious applications, battery size, capacity and cost remain the big hurdle...

Until technology comes out that vastly supercedes Lithium ion phosphate batteries its never going to be a real "thing" that has wide or realistic appeal for the average boaty....

I was looking at a boat made by the guys that are building Mooses boat in NZ and came across their version of an electric cat..

Here is a review here for anyone interested..

It just seems a little weird to pay 1,25 million bucks for a luxury boat that runs off twin electric motors but can only run for 2 hours and cover 36 nautical miles and then you have to start the diesel generator to recharge the batteries so you can keep going..

I dont know how "green" such a concept actually is..?

Maybe its a step in the right direction and when battery technology radically improves it will have more practical appeal..

Great for the dams or on a yacht tender,but out of all the battery operated things these days like tesla cars and this electric outboard not one sign of solar paneling on any of them surely by now the cowling on that outboard could have been solar or on the body panels of a tesla or any other electric car just to charge a bit while useing it would be better than nothing and useing coal to recharge it when you get home,they have some fooled.

The battery pack looks to be around 1500Wh at a guess, based on its size. If it's around 3hp (~2200W) then it'd go for around 40 minutes at WOT. If less then longer, but <3hp isn't going to do much even on a small tender.

Just rough numbers but it won't be far from that - storage density just isn't there with batteries yet. Interested to see its specs though.

surely by now the cowling on that outboard could have been solar

Not worth it. The highest density commercial solar cells right now produce 224W/sqm so with maybe 0.2sqm of cowling actively generating power, that's just 45W under peak generating conditions - though realistically probably half that because the sun won't be at the optimal angle (whereas rooftop panels are somewhat aligned). A full solar charge would likely take more than a week under sunny conditions.

Solar panels on a boat will never work specially at 12 volts
there just isn’t the sqm there to provide any meaningful charge

Facebook is full of guys with a single 120w panel screwed to their tinny and taking up valuable space and going this covers all my usage when in reality they just don’t use much of their battery’s output

To have a serious 200 hp electric unit going off ev vehicle ratings you would need a battery pack of around 500kg
that would give you the 150-200km range offshore boats want to be useful

which may be doable in the coming years but then who wants 415 volts and the risk of leaving the Bungs out

I believe bluescope steel are trialing nano partials that are able to collect solar in their paint so your entire roof wil become one big solar panel . Matt

Well, Mercury released some concepts at the Miami Boat show recently. Only small hp, of course, with removeable battery packs to change on the run. Looks interesting.
