Your amps are going to be the same even at low rooms. Think of amps as power to turn something. It does not matter how fast it goes it is how hard it is to turn.

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. Depending on wind conditions. I am thinking that if I switch to a three blade propeller I might get a bit more push at low RPMs. VERY HAPPY with the conversion. Gennaro

I own a 1989 Mirage 29, which currently has an original Volvo Penta 2002 diesel motor. I am considering converting to electric - the old motor won't last much longer, and the admiral hates the smell!
I have looked at the 10kW Thunderstruck motor - it seems to be a good match. I am struggling with battery capacity, however. If I wanted an endurance of, say, 5 hours at 5 kts, what would I need? I would consider LiFePO4 batteries - expensive, but apparently long lasting.
Any comments or guidance you all could provide would be much appreciated..
Dave
