Supposedly 42 gallons, but there were some that went out the door with less. Brother's 201 run empty topped out at 34 gallons if I remember right. If you have the cooler under the middle seat I think it is 32-34 gal., if not it should be 42-44. By the way, don't trust your fuel gauge, mine on "empty" has about 12 gallons left in it. Not that that is real bad, but I need to know when it reached the "E" before I can figuure how much further I can go. I hate looking down and wondering how long it has been on empty!!
