    hello,

    I haven’t rebuilt a powerhead in a while, but in the day I’ve rebuilt hundreds..
    I recently went through my 2000 90HP merc so I can bring it to factory specs. I’m stuck at a certain rod/cap alignment on only one rod.
    The other two rods are perfectly matched my finger nail (and an awl) runs smooth across both side surfaces on two rods with the exception of one. One side of one rod seems to be aligned perfectly, the other side (regardless how hard I try) does not seem to be
    perfectly matched. Specifically there’s a very small area in the middle of the surface that is smooth.. The outside edges of the flat surface however is where I can slightly catch my fingernail. I noticed from the factory that the outside edges are rough (when they cracked the rods) I guess my question is if one side of the rod is perfectly matched and the other would catch my nail if I try very hard, should I worry and try another rod? I’ve read a few posts that new rods are prone to this as well.
    Thanks!
