This website is focused on cruising yachts. Electric motors - inboard or outboard - are only practical when you have access to shore power to recharge their batteries. I don't think you'll find anyone here would be interested in using one for those reasons.
We tend to use 2-stroke or 4-stroke outboards for dinghies mostly, although some lightweight yachts may also have an outboard as their secondary propulsion - primary being the sails - in lieu of an inboard diesel. In the main diesel is preferred for reasons of reliability, economy and safety.
Personally I know of only three people using electric. One is a weekend sailor who recharges his inboard system on shore power. Another is well-known adventurer Webb Chiles, who uses a trolling motor as his primary propulsion while in harbour to reach a mooring. The third is my brother, who keeps a trolling motor on his aluminium runabout as a backup in case his outboard fails while lake fishing.
None of these uses are in open water, as you can readily tell. An outboard of any type is mostly unsuitable for that.
