Maintenance

●Keep hands, hair, and clothes away from the flywheel and other rotating parts while the engine is running.

7.Run the engine at a fast idle for 10–15 minutes in neutral position.

8.Just prior to turning off the engine, quickly spray “Yamaha Stor-Rite Engine Fogging Oil” (Part No. LUB-STRRT-12-00) alter- nately into each carburetor or the fogging hole of the silencer cover, if equipped. When properly done, the engine will smoke excessively and almost stall.

9.Remove the outboard motor from the test tank.

10.Install the silencer cover/cap and top

cowling.

Always follow these preventive measures:

●Avoid bodily contact with electrolytic fluid as it can cause severe burns or per- manent eye injury.

●Wear protective eye gear when handling

or working near batteries. Antidote (EXTERNAL):

●SKIN - Flush with water.

●EYES - Flush with water for 15 minutes

and get immediate medical attention. Antidote (INTERNAL):

●Drink large quantities of water or milk

followed by milk of magnesia, beaten egg, or vegetable oil. Get immediate medical attention.

●Charge batteries in a well-ventilated ar- ea.
