It weighted 935 pounds empty. The adjustable prop on the O-200 should develop more Hp at the prop TO speeds than my fixed pitch prop on my 115HP O-235. I would check the pitot system, RPM indicator, and lastly the prop efficiency in that order. You can borrow my Prince prop (62/69) if you feel the prop is the problem. Don G, the Lancair test pilot required a static 2250 RPM with the O-235 before he would test fly a new Lancair 235. Rusty
