Sorry, but I have to differ with your assumption of "no emissions'. You may
well have "no emissions" at the outboard motor location, but the power plant
that provides the power to charge the electric battery creates a LOT of
emissions. Sending that power over electric lines isn't a very efficient
system, either.

Many people keep their batteries charged all day and all night, even if they
are not using the battery currently. Heck, I'll bet you personally have a
dozen little black boxes plugged into wall outlets right now, and half of
them aren't doing anything that is needed 24 hours a day. Your TV with
"instant on" is running on one of the black boxes 24 hours a day...it has
"no emissions"....not really so at all.......

It isn't a simple case of "no emissions" for ANY electric battery device.
Golf carts are a simple example of lots of charging being done, whether the
cart is used/rented or not.
