I imagine that parts for those three years are going to be the same. Correct? I rescued this engine from the recycling center. I have a “bad habit” of doing that. I am also a barn find junkie. The previous owner said it ran about five years ago and quit firing. I gave him $200 brought it home. Checked compression. 115 on both dry. . Little deep creep and mix oil in cylinders Looked it over. Disconnected kill switch black/yellow wire. Fired on fourth pull. Now carb and water pump kits along with thermostat. Man I love my OMC engines. 26 total. Thank you for your help and ear. Happy to be here.
