The 90 degree gear box on my ultra puked last week. I called and ordered it overnight. I wasn't surprised at the freight charge but $250 for the GEAR BOX???????????????. I replaced the entire transaxle last month for $475. How can that little piece cost $250? I like the machine but with just 500 hours Ihave replaced: 2 pumps 1 starter 1 diode 1 carb 1 ign coil 1 shutoff plate 2 throttle cables 2 neutral switches 1 kill switch 1 battery 1 paddle Now waiting on new safety unit. Is this unusal? I am very meticulous with the maintenance of this but JEEZ!
