Yamaha 15 outboard manual

An optimally balanced crankshaft and labyrinth exhaust deliver smooth power, while Microcomputer Ignition adjusts timing to maintain maximum engine performance, economy and power under all conditions. An intake silencer and manifold on the F20 and F15 result in more direct airflow, for minimum noise and maximum power. An acceleration pump on the F20 and F15 gives the engine the fuel it needs--when it needs it--like during rapid throttle advance.

This ensures responsive acceleration. 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. A Freshwater Flush Device allows you to flush the engine without running it, for added convenience and extended engine life.

Incredible light weights, built-in resting pads and carry handles, an easy oil retention system and an optional folding tiller handle, allow for easy carrying and on-side storage without oil leakage or cowling scuffs.
