Michael,
All the EY units use belts. The assemblies are pretty simple to work on, consisting of bolted together aluminum extrusions and plates. Changing a motor only takes a few minutes. The belt takes a little longer since you have to do a little more disassembly, but it's all really straight-forward nuts and bolts stuff.
I like your idea about publishing some better assembly drawings/photos, I'll mention it to Scott next time I talk to him. In fact I have been bugging him to hire me to do some 3-D models and electrical drawings and such, but so far he hasn't bit. Meanwhile I'm sure he'll be happy to give you any info you need if you give him a call.
I also like your "all electric" boat concept. My brother Scott (of Electric Yacht) has been talking to some industry folks and apparently it's a concept that's been getting some attention. I think it has real possibilities if well executed.
I'm planning something like that for my little Albin 25 trawler. I've got room for about 1KW of solar on the hard-top, and will probably do a deployable wind genny and a tiny Diesel gen-set for backup. I don't think anyone sells a turn-key system, but most of the components are available from various sources. It's mainly a systems integration task. That's what I do for a living, but on airplanes, so I'm thinking I might be up to the challenge. Should be fun. I'm hoping to start buying some of the big pieces this fall.
I'll try and work up a blog or something as I go along, and will continue to haunt this group.
Cheers,
Jim McMillan
