2003 Yamaha 9.9C and 15C Outboard Motor Service Manual.
Because of their reliable design, relatively simple construction, and ease of repair; outboard motors are the ideal machine for maintenance and repair at home. With proper care and routine maintenance, an outboard motor will provide many years of reliable use. When repairing an outboard motor, most home mechanics will find them easy to work with and repairs quick and trouble-free.
Routine outboard motor maintenance starts right after using the motor. After the outboard motor is out of the water, flush it with clean water. This applies to both outboard motors used in salt water and motors used in inland lakes and rivers. After flushing the engine, disconnect the fuel lines and let the motor exhaust any residual fuel in the carburetor and fuel lines. After the engine has been flushed and the fuel lines and carburetor have been depleted, open the engine cowling and check for any leaks or other obvious problems.
Scheduled outboard motor maintenance should occur frequently. This routine outboard motor maintenance should include changing the oil, inspecting the propeller, inspecting the power trim and power lift system, changing the spark plugs, and replacing the fuel filter. Having a quality service manual specific to your outboard motor will help you identify the parts of your motor and assist you during routine maintenance.
Doing routine maintenance on your outboard motor at home provides many benefits. It is less expensive than having a outboard motor shop or marina do the maintenance. It prolongs the life of your outboard motor. And, it provides you a better understanding of the working components of your motor.
Even with diligent routine maintenance, outboard motors may require periodic repairs. In the event that you need to repair your outboard motor, it will likely be easier if you have been doing your own routine maintenance as you will be more familiar with the mechanics of your motor. Another asset that makes outboard motor repair easier, is access to quality service manuals and parts catalogues.
