The Yamaha F15C outboard engine has quickly gained a reputation for superb performance. This is because it is closely related to the equally highly regarded F20B. Both engine share the same 362cc capacity powerhead, which offers excellent torque to punch a boat up onto the plane, combined with very low engine noise and great fuel economy. On the tiller control models, not only is the gear lever mounted at the front of the engine maximum for operator convenience and comfort, but a quick adjust steering friction lever is also mounted at the front. A 10 amp alternator is standard on all models, as is Yamaha’s almost legendary reliability. On the 15hp model, a tiller control, but electric start version is offered suitable for long shaft transoms. Both the 15hp and the 20hp offer standard and long shaft models with hand start, tiller control, or electric start, remote control. Also available are some remote control, electric start models which even have power tilt, enabling the operator to tilt the engine at the press of a button!
