There isn't an [propulsion] Engine(s) as you are assuming (normally, you'd be quite right).

Currently planned: There will be two 14KW PM DC motors for propulsion. 1KW Solar, 40KW Batteries & 5-8KW Diesel Generator (+ occasional 3.5KW Shoreline). It's an 'all' electric boat (well Diesel/Electric Serial Hybrid technically speaking due to generator - and the 5KW Diesel water heater previously mentioned).
