Electric outboard

while out walking round the edge of a lake here in china i spotted this ! A electric outboard !! no gas powered motors allowed on the lake

 

Less expensive than a http://www.rayeo.com/ I bet.

System 200, 2.5 HP, 36V GE Motor
$4,690.00

System 300, 4.0 HP, 48V GE Motor
$4,690.00

System 500, 5.0 HP, 60V GE Motor
$4,820.00

 

Has anyone used an Aqua Watt electric outboard? They are rated at 30 hp electric.

Why wasnt all this bought up a while back when some one was posting something about the possablities of using electric outboards !!

Great must be really quiet !!

 

It was talked about but does not appear to be in actual production or be geared for displacement boats.

 

build this system in China , the cost less than 300USD
the outboard (with out engine) 120 USD
Motor less 180 USD.
Great solution.

 

A quick look at the site tells the tale, a 20 KW outboard, not counting batteries is a 206 pound pound beast and only able to do 23 knots, but most interestingly not noted was for how long could it do this 23 knots. The video shows one of the most efficient boats to get up on plane and it wasn't moving very fast, at least by American standards in a boat of that size with a 25 HP gas outboard. The cost is high comparatively as is the weight penalty, which doesn't included battery weight, nor cost. A 25 HP gas outboard is less then 3K at full retail, plus a $100 for a tank, line and bulb.

In short, I don't think they've solved any of the usual issues associated with this propulsion arrangement, yet.

As to this:

I think you might be able to do this, given all the 9 year olds working on it, but how long will it last? A year, maybe two months after the warranty period? The world has seen what happens when a ridiculously cheap, Chinese knock off is produced. Yep, we've all learned this lesson the hard way.
