I'm replacing the water pump impeller on a 1980 Johnson 70HP 2 stroke.

When I removed the pump housing, there was a small (1/2" long, 1/8"
diameter) round, bullet shaped piece of metal laying inside.

Does anyone know what this piece is, and where it fits ?

better yet, does anyone have a shopmanual page for the pump assembly,
they can share or trade..? (trade for 1980's Honda BF7.5 4 stroke
shop manual)
