My only complaint about the motor itself is that it doesn't tilt as far as a gas outboard. Mounted on my transom fixed mount, it cavitates in chop yet the prop drags when sailing, even on the "high" tack. I'm in the middle of building a bracket to allow me to attach a 2-stroke lifting aluminum motor mount on the opposite transom.


IME, the latch on the Torqueedo is not at the maximum tilt that the hinge allows. We use a wood wedge to hold the motor up at max tilt and it makes a big difference.
 
The batteries for the 1003 model that I've looked at are 18650 LiNiMnCoO2 ("NMC") in a 29.6v nominal series - parallel array. They are charged using an external 12 or 24 volt (newer versions) power supply and they have an internal boost converter and balance charger. Not sure if they use the same arrangement in yours but if they do it might be possible to charge them from your LiFePo4 bank via the 12/24 volt charging system. There would be "details" I suspect but maybe worth exploring.

I would not recommend buying it without local supplier who can take the responsibility...

If nothing else the batteries can be a PIA ship. On the models where the control systems are in the battery box most of the bits that might need service are going to travel as hazmat.

Looks lovely. Might be worth getting a dye test while it's in the shop.

Svendsens says these cannot be serviced, too old.  Should I really go to my car service shop?  I am glad I put it in a bucket because it is leaking. 

I'd take it to the local machine shop. The bay area has everything so there's probably a specialist hydraulics shop, but, IME, job shops will be able to replace seals and hone surfaces for you.

70 amps is stated draw, other windlass may be more or less.
 

 

And that 70 Amps probably isn't continuous - when a DC motor starts it pulls stall current instantaneously and for a very short period.  So you have to take that startup current into account when fusing etc.

 

I would be surprised if it actually ran at 70 amps continuous.

 

 

Yep. The motor in the example is listed as 500w.
