Re: [Electric Boats] Re: Hello, New to group - do I have enough data to consider con

As for myself I have enough roof space on my 41 foot cabin curser for
a 2kw array, The total cost for my system will run about $7000 for
the array and high end inverter/charger.
I will spend another $7000 on batteries and another $6000 for the
motors and controllers. Thankfully I already have 6.5 KW generator
that I will keep. So I'm looking at about $20,000 to re-power hybrid
electric with solar cells mostly for house loads. I plan on spending
lots of time "off the hook" so the costs work for me. I would have
loved to use two of the Steyr motors if they where just not so
unreasonably priced. As it is just one of them cost more then my
total expected re-power cost plus I get a "free" battery bank and
solar array.

I wish some more companies would inter the marine hybrid market to
help drive down the insane prices. Those 250 hp Steyr hybrids would
start to be interesting to me at about $8000 apiece.
