Yamaha offers consumers great variety with its four-stroke outboard motor lineup. In 2011 alone, the company featured 10 different four-stroke makes with dozens of different models. Each had unique engineering specs, power capabilities and intended uses. But despite this great variety between different models, Yamaha’s troubleshooting tips remain nearly identical for all of the company’s four-stroke outboards. Yamaha includes troubleshooting tips and specific part requirements in the owner’s manual for each of its outboard motors.
Use the Yamaha outboard’s starter. If the starter motor doesn’t engage and the engine doesn’t turn over, the electrical system may be at fault.
