Rebuilding a Johnson or Evinrude outboard motor between 20 and 75 horsepower? You're gonna need piston rings! This is a brand new set of standard (STD) size piston rings, part numbers 0396377 and 0385807. They come from BHMarine and are fresh in their original packaging, just like you'd find at a marine parts store. These are crucial for sealing the combustion chamber, so if your motor is losing compression, burning oil, or just in for a full overhaul, these rings are a must-have. Make sure these part numbers match what your engine's service manual calls for. Always measure your cylinder bore before installing any rings to ensure a perfect fit. Whether you're a professional marine mechanic or a seasoned DIY boat owner tackling a rebuild, having the right rings is step one to getting that outboard running smooth and strong again. Don't forget the gaskets and other rebuild bits while you're at it!
