Re: [electricboats] Electric Drive Update

I just added a bunch of photos and descriptions of the mechanical parts in my drive unit here:

There's links to the other stuff at the top.

Still more to come as I find time to post it...

The Kubota motor was removed from a brand new Kubota excavator that was converted to all-electric.  So it is used with maybe 1hr of running time.  2019 dates on the tags.

The Motenergy ME1616 motor is water cooled.  Same motor I am using for propulsion.   I also have a closed circuit FWC system with heat exchanger as I do for the drive motor.

Where are you located?  I am in USA, OH on Lake Erie.

I did much the same. I used a Motenergy motor direct to the flywheel of a Farymann diesel I salvaged from a Westerbeke 4kW generator. At 3,600 RPM it didn't get high enough voltage to charge. 

then I purchased a PMAC generator on ebay and belted it to the Farymann producing plenty of volts. Over the summer the Farymann froze up solid - so out she came. 

Next was a cheap gas "range extender" from AliExpress. It worked fine until it caught on fire. 

I assume that your Kubota is used? Or new? Is the Motenergy Motor  water cooled? My drive motors are water cooled so I have a closed circuit fresh water cooled by a heat exchanger using SES water and 2 pumps.
