Thank you to everyone that has provided comments thus far. Just to
clarify, the intent of my questions is to determine what the customer
values when they decide to purchase a small outboard engine. I realize
that battery technology has a way to go and may not be significantly
improved for a number of years. But there are some advances in electric
motors that can more efficiently utilize the battery power and
therefore provide either more power (up to 10HP or possible greater) or
greater lifespan utilizing the existing battery technology. I also
realize there are a number of smaller companies that do offer electric
outboard motors as a primary drive, however I am looking at different
markets to see if there is enough demand for for a major marine
producer to step in and provide a product on a larger scale. Any help
that you can provide will help me in providing good recommendations. As
a follow-up to my first question I would like to know what attributes
you primarily look for in a small outboard (either gas or electric) for
an auxiliary drive on a sailboat. Additionally, how much more money
would you be willing to pay over the cost of a small gas engine of
similar HP for those additional benefits (quietness, low vibration, no
emissions, etc.)?


Perhaps you didn't understand the first time so let me summarize and
tell you again.

It's not the motor that's the attraction no matter how great the motor
is. Physical law dictates a certain energy use for the work the motor
does. Electric motors in the ten horsepower range, for example,
demand huge amounts of energy. The only real viable way to run
one would be to run a gas or diesel generator to provide the electricity.
Storage batteries won't cut the mustard for boat application. They are
too heavy, too costly and too bulky.

You don't have a plan until and unless you address the issue of how
and where the electricity to run your electric outboard comes from.
