OMC engine in skidsteer was this engine put in any skidsteer?

I have been told that this model of engine was possibly the factory power supply for a skidsteer and I would like to hear if this was ever indeed true. I do not no the suggested year/s of its use or the company name that may have used it. Its a 2-cycle twin apposing cylinder air cooled that was for sure used in snowmobiles such as evinrude. It's currently mounted on my big go-cart. Look at these pics to see if it looks familiar to any skidsteer's power plant. Thanks for your opinions, datsunman;
