Re: Repowering with an electric engine?
Agreed not for the cruisers, but I have done it on my Oday 28, gets me in and out of my club no problems.
Basically zero transmission losses, no warm up time, full reverse to full forward as fast as you can rotate the throttle.
Depth of discharge never an issue, while day sailing I recover to full SOC by the time I'm ready to come back to the dock via prop generating while under sail.
Definitely has limitations if you're not on the dock each night, or if fighting tidal or river currents etc..... But I'm just n Lake Ontario, docked each night and "plugged in" still 2-3 days for short duration outings and to anchor etc....I have no troubles.

Very clean, no smell & very minimal noise
On weight it was basically a trade off for me, batteries in tray where old engine was, boat balanced the same.
