Thanks, Mike. You and Bianka have pointed the way for a lot of us e-boaters. Your Thoosa setup is pushing a boat 3' longer and over twice the displacement of mine, so yeah your system is doing great. Or maybe more to the point, mine is still not optimum. The new tach will tell me a lot when I get it installed. I think I am looking at changing from a 2:1 gearbox to a 3:1. Maybe even 4:1. I don't need to be climbing my own bow wave at full power when I could be improving my efficiency in the 2-3kt range instead. I want to try the 12kw motor again, too, now that I have a decent sized prop. I have a DVM that has an IR thermometer and I want to get some temperature data in the next round of tests. I ran it tied down at the dock at 5a for 6 hours the other day and neither the motor nor the controller got warm to the touch so that's encouraging.
