2021 Yamaha 9.9HP Outboard Motor
Our 212-cc 9.9-hp portable is an impressive little outboard with a new, shorter tiller handle for increased comfort and the option of manual or electric start. The F9.9 platform is so popular, we also offer it in a high-thrust T9.9 format. The high-thrust model offers the option of a 25-inch shaft and a V MAX SHO® sport cowl when used as a kicker on a multi-species boat.
Reliability & Durability
- Optimal Operation: A CDI Microcomputer Ignition monitors throttle position, engine speed and atmospheric conditions in order to precisely adjust ignition timing under all conditions for optimum ignition performance, ensuring smooth and reliable operation
 - Corrosion Protection: Combined with our proprietary alloy (YDC-30), our exclusive Phaze Five™ anti-corrosive paint system provides a tough, five-layer barrier against corrosion. This protection is standard on all Yamaha four-stroke outboards.
 - Engine Warning System: Protects the outboard with a range of functions including: overheat protection and low-oil-pressure warning (automatically reducing maximum RPM to 2000), over-rev protection, start-in-gear protection and shift-in prevention at open throttle.
 - Solid and Dependable: Incoming air is routed through the Air Intake Labyrinth System that traps and drains water before it enters the engine’s intake for maximum reliability.
 - Wet Sump: A pressurized oil delivery system incorporates a compact and durable oil pump to keep all of the moving parts of their SOHC systems lubricated and running smoothly for maximum reliability.
