I just did the livewell flush and flushed the recirc. Cant believe i use to pay to have it done. I opened all valves and it pumped up to the front and back no problem. I only used about 2-3 litres. I also leave batteries in and plug in to charge once a month. I give them a good check (fluid levels, hygrometer and voltage) before i put it away. Not exactly putting it away yet just wanted to flush livewells with the upcoming temps
