    While many additives available may reduce deposits, Yamaha recommends the use of Ring Free Fuel Additive, available from your Yamaha dealer. Ring Free has repeat- edly proven its ability to clean combustion deposits from inside the engine, notably the critical piston-ring-land area, and fuel sys- tem components.

  • Page 59: Filling Oil

    EMU01801 FILLING OIL This engine uses the oil injection system, which provides superior lubrication by ensuring the proper oil ratio for all operating conditions. No fuel premixing is needed.

  • Page 68: Trimming Outboard Motor

    EMU01412 TRIMMING OUTBOARD MOTOR The trim angle of the outboard motor helps determine the position of the bow of the boat in the water. The correct trim angle will help improve performance and fuel econo- my while reducing strain on the engine. The correct trim angle depends upon the combi- nation of boat, engine, and propeller.

  • Page 69: Adjusting Trim Angle

    ADJUSTING TRIM ANGLE EMU01657 Power Trim/Tilt Models 8 Be sure all people are clear of the out- board motor when adjusting trim/tilt angle, also be careful not to pinch any body parts between the drive unit and clamp bracket. 8 Use caution when trying a trim posi- tion for the first time.
  • Page 70 EMU01916 Trim angle settings and boat handling When the boat is on plane, a bow-up atti- tude results in less drag, greater stability and efficiency. This is generally when the keel line of the boat is up about 3 to 5 degrees.
