I ended up with a box of what appeared to be NOS unused OMC Johnson Evinrude lawnboy parts. These two pieces were in there. One has a crack in the threads/casting portion. See pictures. This piece looked dirtier than the other. The other piece is marked "NO BRASS" and is obviously UNUSED. I will include them both, though the New looking casting piece does appear to have some brass installed. Any questions let me know, not sure what we have here. Both are marked 678500
