With forward-mounted controls and optional power tilt, they make operation easy”perfect for spending a full day fishing the lake or skimming the marsh with your decoys. They also serve as excellent kickers on multi-species boats, with the 9.9 even offering a high-thrust model and an optional V MAX SHO-style sport cowl for a consistent look. Add a little more power to your day with Yamahas portable F9.9 and F8.
Power & Performance
Compact, lightweight design: A two-cylinder, single-overhead-camshaft platform and streamlined intake manifold provides an efficient, light design.
Responsive Acceleration: An acceleration pump on the F9.9 and F8 gives these engines the fuel they need--when they need it--like during rapid throttle advance. This ensures responsive acceleration.
Streamlined Intake: An intake silencer and manifold on the F9.9 and F8 result in more direct airflow, for minimum noise and maximum power.
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.
Convenience & Control
Smart Evolution: The F9.9 and F8 feature a new shorter handle for more comfortable operation. This also ensures that when the handle in hinged back, it tucks in tighter to the cowl for more stable, flexible storage.
Portability and Storage: Built-in front and rear handles make these lightweights easy to carry. Resting pads and an easy oil retention system allow for convenient on-side storage without cowling scuffs or oil leakage.
Propeller Protection: Yamaha's Shallow Water Drive, standard on all 9.9- and 8-hp tiller handle models, helps keep the propeller and lower unit out of harm's way in shallow water.
Model Specific Features
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.
