3.With the engine off, turn on the water sup- ply and let the water flush through the cooling water passages for about 15 min- utes.

4.Turn off the water supply, and then dis- connect the garden hose from the garden hose connector.

5.Connect the garden hose connector to the fitting on the bottom cowling and tight- en it securely. NOTICE: If the garden hose connector is not properly con- nected, cooling water can leak out and the engine can overheat during opera-

When flushing the cooling water passages with the boat in the water, tilting the outboard motor up until it is completely out of the water will achieve better results.

WARNING

These procedures require mechanical skills, tools, and supplies. If you do not have the proper skills, tools, or supplies to perform a maintenance procedure, have a Yamaha dealer or other qualified mechanic do the work.

The procedures involve disassembling the outboard motor and exposing dangerous parts. To reduce the risk of injury from moving, hot, or electrical parts:

●Unless otherwise specified, stop the en- gine and keep the key and engine shut- off cord (lanyard) with you when you perform maintenance.

●The power trim and tilt switches operate even when the main switch is turned to the “” (off) position. Keep people away from the power trim and tilt switch- es whenever working around the out- board motor. When the outboard motor is tilted, keep away from the area under it or between it and the clamp bracket. Make sure that no one is in this area be- fore operating the power trim and tilt mechanism.

●Allow the engine to cool before handling hot parts or fluids.

●Always assemble the outboard motor completely before operating it.

Maintenance, replacement, or repair of the emission control devices and system may be performed by any marine engine repair establishment or individual. All warranty repairs; however, including those to the emission control system, must be performed by an authorized Yamaha marine dealership.

A service manual is available for purchase through your Yamaha dealer for owners who have the mechanical skills, tools, and other equipment necessary to perform maintenance not covered by this owner’s manual.
