Hi cptstarz1004 (?)
You should really start by thinking about the boat, rather than the engine that happens to be in it. Typically, an electric drive should be about 1kW of rated power per ton of displacement for sailing auxiliaries.
Without any information about your boat, I can say that the 5.5kW (7.3hp) drive that I purchased from Propulsion Marine is more powerful than the Yanmar 12hp diesel that came out of my boat.
You may find that solar is good for charging your boat while you're away, but most reasonable size arrays won't drive your boat very fast by themselves. It all depends on how you use your boat.
Batteries can be bought at Walmart, battery stores, marine stores or online depending on the batteries that you want. The rest of the drive can be purchased from electric boat vendors that you can find online for complete systems, or from EV vendors for random components that you can try to figure out how to make work in your boat. If you go the full DIY route, you can find help online, including in this group.
But first, let's hear about your boat and how and where you intend to use it.
Fair winds,
Eric
Marina del Rey, CA
