How do you plan on using your dinghy
mostly? What type of cruising do you do?
For what it is worth, electric outboards are no more "green" then a 2 or 4 stroke outboard
. So if that is your only consideration, I would stick with gas. Making a battery
is a terribly toxic proposition.
Do you have solar
? How would you charge the battery? If you have to run your diesel
to charge the battery are you saving anything?
Just things to think about.
No used 2-strokes where you live? Parts
and mechanics are easy to find for those...and easy to do yourself if you get the service
