submerged evinrude 175

took the starter off and took it apart. didnt look bad but i hit it wiyh the water hose anyway and let it dry. was on front porch putting it back together when some dude lost his trailer right in front of my house. i dropped everything and went to street to see if anyone was hurt. came back and one of those little springs is gone. apparently never to be seen again. any idea where to find one?
