Re: [Electric Boats] Electric Yacht system

 

Thanks for the info. The prop clearance issue remains paramount to me
after reading your issues. The prop size determines the formula to set
up the controller. I will contact Scott and sees what he has to say.

I have just been reading about Lithium Iron Phospate (LiFePO4) batteries,
and was wondering if any one has used one for marine application ?

I have two banks of batteries for range and redundancy. So far (May '08)
in the real world I haven't needed the second set for range. As I've said
before I did have issues with a battery going bad in one bank and it was
nice to have a healthy bank while working through the problems on the
sick bank. By the way the sick bank is all better now.

Regarding the prop, I tried putting a 13" CDI Extendo on my E27 and it
was too long (would not clear the rudder because of the extension) I
think I have a 2" hull clearance with the 12" prop. When installing the
motor you might be able to slide the prop shaft back enough to fit your
larger prop or maybe get a longer shaft. But even at that I can't imagine
you will have the hull clearance you need.

Please keep me up to date on what you do, if you can get a 14" prop on
your Ericson 27 you might be able to motor around the world ;-)!
