electric outboard

[CalmSkipper]

Does anyone have experience of the torqueedo 801 electric outboard. They're becoming far more competitive price wise but it would be good to hear from someone who has used them to unerstand performance, range, how easy to re-charge, reliability etc?

One of a range of small electric outboards They are very low power and have limited range but if you want to travel small distances slowly in near complete silence then maybe they are just want you want. They have been discussed on here before or at least the Cruise model was so a search should find what has been said before but note the correct spelling is Torqeedo.

look at all the details and especially the technical specs on the Website

Perhaps when you have digested it all you will be able to explain how a motor with a propulsive power of only 350 watts can be claimed to be comparable with a petrol engined outboard of 2hp when 350watts is less than ½hp. or how the Cruise model with a propulsive power of 900watts (ie about 1.2hp) can be compared with a 5-6hp petrol model.

Happy reading!

indeed vics, and if you think it will push you along, how are you going to generate 350 or 600W of power to recharge your batteries ???

Possibly worth a mention but I thought that the torquedo range was quite different than then 'usual' lot in that it runs on AC and is supposed to be quite a bit more efficient.???

Isn't it all to do with the shape of the propellor, and the rotational speed ? I think they claim "equivalent" (my word) power. But it is a moot point. perhaps one should arrange a tug-of-war in the style of Rattler and Alecto ? It would make a good article (hint, Richard)

If I remember correctly... /forums/images/graemlins/wink.gif
blade element efficiency} = \frac{V_a}{2\pi Nr}\times\frac{1}{\tan(\varphi+\beta)} which mught be useful if we could understand it !

Absolutly no good for use on an inflatable dingy, just cant propel them as one would hope.
I tried mine a few times and was very dissapointed with the performance, just went and bought a 2.5hp 4stk petrol ob. although my trolling motor ( as that is what they were actually designed for) is a Minnkota 46lb thrust and could push a 14-17 grp loch fishing boat all day without a bother, but hopeless on the dingy.
You will need to buy one designed for salt water use if that is where you will be using it, otherwise it will corrode very rapidly.

[/ QUOTE ] The claims are actually based on thrust. Quite different to power and IMHO it's a misleading comparison.


As far as charging the batteries is concerned of course you only have 40 watt charger so after every hour of running you have to go ashore and charge the battery for 10 hours.

my intended use is for an inflatable tender...so Clyde, thanks for your feedback.
