Hi Rob,
A Newport 30 with a displacement of less than 9000 lbs will be fine with a 5kW drive. You can buy a more powerful drive, but you will probably rarely use the extra power. My Bermuda 30 that displaces more than 10,000 lbs spends more than 95% of the time running at less than 3kW. Using more power can drain your batteries pretty fast.
There are a number of vendors that will sell you a bow full of parts that you get to adapt to your boat. Personally, I recommend getting an engineered system from one of the four vendors that have been part of this group for many years, I suggest that you check out Advanced Marine electric Propulsion, Annapolis Hybrid Marine, Electric Yacht and Propulsion Marine. Each of these vendors have a number of successful conversions represented by members of this group and have been supportive of the work being done by people here.
I personally chose Propulsion Marine based on my perception of price, performance and value and would recommend them highly. That said, I haven't heard of problems with any of these vendors. I do suggest that everybody considering converting to electric should do their own research and make the choice that fits them best.
Fair winds and smooth seas,
Eric

> I am a new member of this group and just wanted to tell you a little about myself. I hope to meet many fellow electric enthusiasts here. I also hope to gain more knowledge about electric setups. I have a Newport 30 sailboat that I have just pulled the motor out of and am looking over possible electric replacements. I have seen a few different systems that are sold on ebay and have been on a few out here in SF Bay. There doesn't seem to be an end to the number of electric vendors out there. I wanted to know if someone could steer me toward the top 5 so that I could focus my investigations in that direction. I am looking for a electric system that is 48v and about 7.5kw or better. By no means am I savvy in electronic motor setups. I do have a little experience with solar panels, controllers and batteries. I put together a little system a few years back for a home out in the mountains. It worked well. We were able to power a refridgerator, house lights and an entertainment system. We also had a honda generator for those days that the sun wouldn't come out. In any case thanks for reading and I look forward to hearing from you.
