I need to repower my 27' sailboat was looking at a diesel but electric has interested me. I have a strong mechanical background and some electrical experience mostly automotive and a little residential, that being said I can safety repair most anything; it's designing where I may need some help. I have a very healthy respect for electricity and always ensure cables are properly terminated, sealed and secured, all grounds are in place and all batteries secured.
First off budget is an issue I don't want to go over $4K, from prop to batteries, is this possible? Rough guess shaft, prop, bearings, etc $1K. Kit something like Thunderstruck, Sevcon Brushless Sailboat Kit - 8.5KW (http://www.thunderstruck-ev.com/index.php?dispatch=products.view&product_id=55) $1.5K. Wiring, motor mount, belt drive reduction, misc bits $0.5K. That leaves $1K for batteries and chargers, not much I know, but I could add more later. I would thinks 48 volt would be better (at least safer), but amps are starting to get high. Batteries, I guess I would have to go with AGM, have some space, would love LiFePO4 but out of my buget right now. Any one have any suggestions?
