Thanks Eric, it actually didn't occur to me to get the group to help with specific system design and I am not sure why not? We have a 1970 Columbia 36 displacement is stated as 13000 pounds. We were power boaters because my wife wasn't interested in sail, got her on a sail boat and the power boat went up for sale. The plan for the boat is to use it for club racing, day sailing ans the occasional overnight with the kids. I suspect most of its sailing will be club racing.
I am fairly certain that I will be looking for a motor around 8kw and that is about all I am certain. The Asmo dealer recommended their 9kw motor but I suspect that's because they don't have an 8.
Hi Chris,
I would suggest that you start a little higher up by describing your boat and how you expect to use it. Virtually all of the questions that you asked are influenced by these basic questions. The type of boat that you have will dictate different answers. How you use the boat will change your answers as well. So you might as well start at the beginning rather than jump around between random details that will become relevent later.
While every installation has a few choices to be made, the boat and your use case will define many of your system attributes.
Fair winds,
Eric

I have a list of specific questions that I should take the time to write down as every time I read something a new question pops up. Some of the stuff doesn't seem appropriate for this list as it seems most are well beyond my level of knowledge. Is there a good primer? What can I read to learn the basics, I mean the very basics... things like why choose 48v or 72v, or something different? How do you determine prop size? How do I determine hull speed RPM for my prop to determine gear reduction? How do I determine number of amp/hours needed and how do I size the battery bank?
