Power and Performance

Fuel Economy

Precision Multi-Point Electronic Fuel Injection delivers the exact amount of fuel needed for optimum performance and efficiency. Yamaha’s EFI optimizes fuel atomization further enhancing fuel economy.

Single Overhead Camshaft

A Single Overhead Camshaft (SOHC), three-cylinder design on the F40 and F30 provides a compact, lightweight, space-saving design.

Precise Throttle Control

All air entering the engine block is routed through a single throttle valve, to ensure the precise amount of air necessary for optimum power and fuel efficiency. It then enters each cylinder through individual long intake tracks, which are 'pulse tuned' to provide air at the precise volume and timing for maximum density and power.

Convenience and Control

CONTROL AND COMFORT

Our optional, award-winning Multi-Function Tiller handle features a Variable Trolling RPM Switch (VTS®). It allows for precision trolling speed adjustments in 50-RPM increments. Compatible with all Midrange models.

EASY ENGINE FLUSHING

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

POWER TRIM AND TILT

Power trim and tilt models provide a trim range of -3 up to +20 degrees. This brings the bow of the boat up, for better hole shot and top speed and a smoother ride.
