Hello Mike,
I am using a Sevcom controller and display. The data is from the display and GPS on calm water. I have not used a clamp meter yet to see test the correspondence of the display to reality. I will do that as soon as I return to the boat and report.

This note is for Gennario about his installation. You state this as the performance for your boat:
"I can get to 5 knots with 56 Amps – max throttle - I don't do that often. I usually like running at 3 knots at 10-15 Amps."
You may want to check your calibration on your monitor or controller. Not know what system component you have, I do not know how that may be done. But at 56 amps at 48v that is 2688w or about 3.6hp. That is not reasonable to push the Catalina 30 at that speed wt that power. and likely your display data is off. The 10kW motor at 48v will have up to 200amps at full power. It should take about 80amps (5+hp) to get the Catalina 30 to 5kts in calm seas and with no current. At full power you should get to hull speed of over 6kts.
