  • Chrysler 70 Magnapower 70 707HE

    I know this outboard is a two stroke using a 50 to1 oil/gas mixture but isn't there still oil in the engine lower case? No filter, no drain plug, I can't find anything that I would consider lower engine case oil or filter.
    Am I missing something here? Does this thing get lubricated from the oil/gas mixture?

    There is a drain/fill plug at the bottom of the LU and a level plug at the area just above the cavitation plate.

    DO NOT LOOSE THE SCREW AT THE LU BULLET.
    This holds the shift york/fork and if you do it you will have to disassemble the whole LU to put it back.

    The LU shall have gearlube SAE 80-90 or equal. Not with EP additive, because it will affect the bronze bushings.

      The crank, bearings and the piston walls get lubed from the 50-1

      NO other oil in the top of the engine.

      ​NO filter other than one in the fuel pump, unless someone has installed one in the fuel line???

      ​Like Nordin said the lower unit where the prop is has oil/gear oil.
      It has a slotted screw on the side of the gear case.
      DO NOT REMOVE!!

      The drain is on the bottom.
      ​It could have a plastic washer to seal it??
      Replace when changing oil.
      Use Mercury seals.
      80/90 gear oil.
