Q. Is fuel contaminated or stale?
A. Fill tank with clean, fresh fuel.
Q. Is motor angle too high?
A. Return to normal operating position.
Q. Is fuse for electric start relay or electric circuit blown?
A. Check for cause of electric overload and repair. Replace fuse with one of correct amperage.
As long as an engine has compression over 100 psi it will likely run very well. Maybe not making 100% of available power but nevertheless a good running engine. here

The starting system on your Yamaha outboard includes the starter motor, battery, fuel pressure sensor, throttle position sensor, ignition system, starter relay, wiring harness, switches and more. These parts work together to convert electrical energy from battery into mechanical energy to rotate the crankshaft and start the Yamaha outboard engine. Use the directions below when troubleshooting the starting system. here
It is highly recommended you download the factory repair manual for your exact model and year Yamaha outboard. An outboard that won’t start might have many possible causes and solutions. This information is extensive but it might not include every detail that is specific to your model or year. here
Maybe the outboard cranks but won’t start or maybe it won’t crank over at all. Whatever the case, if your engine fails to fire up and start operating, you should refer to the troubleshooting guide listed below.
The ignition system on your Yamaha outboard engine is a system in which fuel-air mixture is ignited so as to fire up the internal combustion engine and keep it running. Parts of the ignition system include spark plug(s), coil resistance and ignition coil leads, spark plug caps, correct ECM output peak voltage and more. Use this guide to trace and correct faults within the engine’s ignition system. [links]
