I saw on your post that you used to have a 81 series O/D. Do you still have it? I would be interested in all you have left for spares. I have an 80 series, and yes, part are hard to find but I have found a dealer here in Wash. that has in stock and knows where all Stearn Power parts from the manufacture are now warehoused in Mich. Please let me know. PS The drive you took off is half again as tough as a bravo, big shafts and big gears. Mine is a 1978 model that has had 565 hp since 1983. only broken U joints and normal main, but parts ARE hard to find. Thanks George Smith (GEO 100)
