If you’re the kind of person who likes to do it yourself, here are some suggestions for performing maintenance on your outboard motor. First, it’s important to note that present day marine equipment is quite sensitive, and represents advanced technological machinery. Make sure to have the proper training before performing maintenance on these sensitive technological systems. Don’t perform maintenance that’s not covered in the service manual unless aware of the procedures and precautions, otherwise, your safety could be at risk. There are simple procedures, like premixing fuel with gasoline and Yamaha 2S oil, which all outboard engine owners should know. However, the service manual is written for technicians who have received special training, and if the manual doesn’t make sense, it’s best not to attempt maintenance. Make sure to have the special tools and equipment needed for maintenance, and never substitute generic equipment (like wrenches, screwdrivers, or hammers) when a special tool is necessary.
For complex maintenance, it’s best to take in the outboard to a local dealer. All dealerships have qualified trained technicians, who can perform maintenance and even provide more advice on how to do it yourself.
