ELECTRIC PROPULSION IS BORING
Someone on a sailing forum recently asked me how things were with my electric propulsion system after seven years of use. I said it is kind of boring. But, boring in a good way. For example I recently pulled BIANKA for the season. All I really need to do was empty the water tanks and winterize the water system. Something I am able to do with one gallon of antifreeze. I certainly don't miss lugging a half dozen or more gallons of antifreeze down to the docks just to winterize the engine. But, first of course I would change the oil which was somewhat of a messy job not matter how careful I tried to do it. Bending over the engine and contorting the body to reach the oil filter was sure to cause a back ache at some point. Squeezing my body down below the cockpit hatch to access the raw water filter for cleaning and to hook up the hose to the raw water pump to flush the engine with antifreeze would often cause a pulled muscle in the confined space too. My clothes wet with water and antifreeze in the cool November air is something I don't miss either. Really the only thing I can think of that I may want to do is install an additional on/off switch to the battery bank and another switch that would provide battery power to the 1500 watt inverter and 48 volt to 12 volt converter. Even this is not an urgent thing. After these projects there is nothing I can think of that really needs to done. Like I said with the reliability and lack of maintenance required on an electric propulsion system things become pretty boring.
