XTO Offshore V8 5.6L 425 HP
Yamaha’s mid-powered Portables, the F9.9 and F8, provide nimble, lightweight, efficient power you can take with you. These SOHC 212cc two-cylinder wonders are both under 90 pounds. They feature carrying handles, resting pads and on-side storage capability; so they easily ride along to the cabin or your hunting spot.
Make an appointment with Tom Ross to come in and see this motor in person.
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.
