3.Remove the top cowling and silencer cover/cap. Remove the propeller.

4.Install the flushing attachment over the cooling water inlet. NOTICE: Do not run the engine without supplying it with cooling water. Either the engine wa- ter pump will be damaged or the en- gine will be damaged from overheating. Before starting the en- gine, be sure to supply water to the cooling water passages. Avoid run- ning the outboard motor at high speed while on the flushing attach- ment, otherwise overheating could

occur. [ECM02000]

5.Cooling system flushing is essential to prevent the cooling system from clog- ging up with salt, sand, or dirt. In addi- tion, fogging/lubricating of the engine is mandatory to prevent excessive engine damage due to rust. Perform the flush- ing and fogging at the same time.

WARNING! Do not touch or remove electrical parts when starting or during operation. Keep hands, hair, and clothes away from the flywheel and other rotating parts while the engine is running. [EWM00091]

6.Run the engine at a fast idle for 10–15 minutes in neutral position while supply- ing fresh water.

7.Just prior to turning off the engine, quick- ly spray “Yamaha Stor-Rite Engine Fogging Oil” alternately into each carbu- retor/each intake manifold. When prop- erly done, the engine will smoke excessively and almost stall.

8.Remove the flushing attachment and wipe off any excess water.

9.Install the silencer cover/cap and top cowling. Install the propeller.

Lubrication (oil injection models)

1.Install the spark plug(s) and torque to proper specification. For information on spark plug installation, see page 63.

2.Fill the oil tanks. This prevents the for- mation of condensation. For models with a remote oil tank, it may be necessary to manually override the control unit to completely fill the engine oil tank.

3.Change the gear oil. For instructions, see page 67. Inspect the oil for the pres- ence of water which indicates a leaky seal. Seal replacement should be per- formed by an authorized Yamaha dealer prior to use.

4.Grease all grease fittings. For further de- tails, see page 63.
