How do you replace the pull start cord on an evinrude 9.9hp?

To replace the pull start cord on an Evinrude 9.9hp outboard motor, first remove the engine cover and disconnect the spark plug for safety. Take off the recoil starter assembly by removing the screws, then carefully unwind the old cord from the spool. Thread the new cord through the pulley and tie a secure knot, then rewind the cord onto the spool while allowing it to retract properly. Finally, reassemble the recoil starter and engine cover.
