During a tropical storm, saltwater got siphoned into my Yanmar 2GM and sat for about a month before I realized it. I tried to salvage the engine, but it was pretty much a basket-case. My wife and I went to the Annapolis sailboat show last October to take classes about diesel engines and we saw a few electric propulsion dealers. After much discussion, we decided to make the switch going with Electric Yachts. We weren't compelled to "go green" with our Hunter 29.5, but now it is an added benefit. I'm sure that electric conversion isn't for everyone, but we do most of our sailing by "coastal cruising" around the northern Gulf Coast and this fits our style perfectly.
I know that there are a lot of talk about electric motors on threads here; mostly to the negative. I'd be happy to answer any questions about our conversion and the benefits we've seen. Send a personal message and we may start a new thread.
