[QUOTE="Butthead, post: 448147, member: 637"] I've noticed this as well. On my old Tracker 1436, with the same two 12v batteries, I noticed a marked improvement on runtime with the 24v 80lb Minn Kota over the 12v 50lb Minn Kota. They were used as main propulsion, so pretty much run at 80-100% for most of the time. After a day of use, I would typically be at a lower charge with the 50 than the 80lb. Since lead acid batteries are sensitive to amperage loads, my hypothesis was that the higher amp draw of the 50 was harder on the batteries, even though the overall wattage pulled was lower. It could also be that the 80 had the digital maximizer, which turns the power on and off very rapidly, versus the Endura that pulled the same power, no matter the speed. But even on my buddies 21' Ranger bass boat, his 20 year old 24v 82lb motor will easily outlast the 12v 45lb motor on my flat bottom 1648. [/QUOTE]
