Harvey, It's a Minn Kota Endura 42, 42# thrust. Typically we operate it on 3 (power settings forward range from 0-5). I usually use it less than 20 minutes per outing, from which the 6 amp charger does its bulk charging in about an hour. I haven't tried to deplete the U-1 battery because complete discharge is said to severely shorten a wet cell's life. Steve Tyree, P-15 Amy Ann
