I made a new discovery last week at work. while replacing a clutch in an older cushman "turf truckster" utility vehicle. i noticed a Daihatsu "D" cast in to the top of the motor and after looking through all of the indstrial governors and accesories, i saw a very familiar looking engine in there... I went straight to the specs in the manual and it is actually a 850cc 3cyl carbureted daihatsu motor. its called a 327 option in the manual. (3cyl-27hp) its only rated at about 3000 rpm though. I locked down the rpm governing slides and took it for a drive... It snapped up over 6000 rpms with impressive power and probably a little more rpm's to spare. I know they changed engines a few times after they abandoned the "OMC lincoln" motors and am not sure how long they stuck with the daihatsu but thought it was worth mentioning here. I used to be involved in the golf/turf forums and saw cushmans for sale or trade often. the engines should be in decent shape if they were held back in the 3000rpm range for pto driven acessories. Most were dedicated trucks for spraying or some other low hours of operation task. I wonder how it would perform in a mini concidering the extra few hundred cc's???
