The Piranha Outboard Motor Database contains technical specifications for most late model Yamaha outboard motors.

Find the recommended rpm range, gear ratio, cylinder count, and many other technical specifications for many different Yamaha models. This information can help you figure out what motor you might have as well as whether your current propeller is working correctly.

At Piranha we have made an enormous effort to make sure our outboard motor database is as correct and complete as possible.

If you find any errors, please let us know so they can be corrected. Also, if you would like to contribute any information that is missing, we would love to add it for everyone to use.
