Johnson / Evinrude outboard help

400 / 800 Series ball gear installation and shimming instruction by T.C. Electronics/Marine tech service representative Wayne Coll

  • The following steps are that of the author Wayne Coll and is in no way connected to or endorsed by OMC or Seloc manuals.
  • Repair help listed is based on the last 500 units or OMC 400-800 Stringer upper gear case repairs we have made.
  • Instruction are going to be limited to what I think the average person doing this type of repair may have at home or work in the way of tools.
  • Tools we use would hit the 10,000 dollar mark or more if you include lathe, mig welder and milling machine to bore housing for the small rear bearing insert.
