A friend and I researched every last 0200 equipped 415 we saw for a while. Although most were actually converted D models with the STC, I did find a few C models with 0200 installations. One just used the STC, which in my opinion was not valid, since the STC clearly stated it was for a D model. Two were done with nothing more than a 337 stating simply "removed C75 and installed 0200 engine". I suppose that satisfied the owner, but quite questionable in my book. I do agree that using the STC directions for the D model, and upgrading to the 1320 GW STC, would be an almost automatic approval, I am an A&P and had decided I would attempt it in that method if I found a good 0200 laying around. I have since decided that the 0200 crank/pistons upgrade to my C85 will be the route I follow. It seems to me that the 0200 is not all that powerful, and seems to use a lot of fuel for the HP, and the crank and piston conversion does a better jub. This is my opinion only, comments of people who have been there, done that welcomed!
