I?ve got a question about shear pin on an Eska 15 outboard motor. I know what it is, and where the spare is located, but my question is about fit! The original pin was sheared, and I had to use a punch pin to tap it out, but when I put in the spare it fits real loose, where it slides by finger touch one side to the other. SO is this the way it should be, or do I need to ?knurl? the center section with a pair of piers so it needs to be tapped into place? THX!
