I installed a 10kW Thunderstruck system with a 2:1 gear reduction and 275 Amp Hours 48 V AGM batteries on my 1979 Catalina 30, original 2 blade propeller. 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
