It seems like a reasonable way to save some amps. From the website it appears to be a simple install and just a case of wiring it in line. Is that the case or do you need to run more wiring? I like ours a lot. The only complaint I have is that it was so quick off the wind in a steep chop that the ride was hard on my daughters stomach! I hand steered a smoother but less accurate course for a while until she felt better. I expect I can adjust the response rate to help that but I haven't yet.
