I just installed an upgraded motor to my M12000. It is from the 9.5XP(6hp) as part of my winch upgrades for my 80. Seems a little faster when respooling, but only time will tell when in use. Also added a dual batt system with a Sears PM-1 with 1150 CCA. I hope this and the single albright solenoid will make my winch unstoppable. After examining the rear cap, it looks like one could modify it and add a fan, a la Endurance 12. I do not have the room for the hose barbs right now, but if push came to shove I am sure I could slide my winch over to one side and make room.
