Thanks for the feedback. I am quite aware of Rays
Outboards. He's the primary reason why I want to build my
own. I feel that his product is more expensive than it
needs to be and since I want an outboard and he is the
only game in town when it comes to primary propulsion
and not trolling then I am making my own. I am using
a very high effency perminate magnet (servo motor)
with rare earth magnets and a PWM Chopper that I built
my self. I also have a some other ideas which should
increase the overall efficency. If I can get the efficency
over 85%, (Ray says that he is between 70 and 75% eff.
depending on where you read) I should be able to increase
the range (discrarge rate) for a given set of
batteries. A 10% increase in eff. at 3 HP would be about a
10 amp change in the discharge rate. At least it
looks good on paper. I want to thank you for the other
information on the prop web sight and the book. Keep in touch
and let me know how you make out.<br><br>Don
