Description

Both propeller-driven and jet pump-driven models are offered in our 747-cc 40-hp intermediate, which offers potent performance in a small package. It offers effortless starting, quick acceleration, and exceptional top-end speed thanks to its single throttle valve, long-track intake manifold, and electronic control module.

Convenience and Control

A Variable Trolling RPM Switch (VTS®) is a feature of our award-winning Multi-Function Tiller handle, which is optional. It enables accurate trolling speed adjustments in increments of 50 RPM. All Midrange models can use it.
EASY ENGINE FLUSHING: For increased convenience and longer engine life, a freshwater flush device enables you to flush the engine without starting it.
POWER TRIM AND TILT: The trim range for power trim and tilt models is -3 to +20 degrees. This raises the boat’s bow for a smoother ride, improved hole shot, and top speed.

Power and Performance

gasoline ECONOMY: The precise quantity of gasoline required for peak performance and economy is delivered via Precision Multi-Point Electronic gasoline Injection. Fuel economy is further improved with Yamaha’s EFI, which improves fuel atomization.
SINGLE OVERHEAD CAMSHAFT: The F40 and F30’s three-cylinder Single Overhead Camshaft (SOHC) architecture offers a small, light, and space-saving design.
PRECISE THROTTLE CONTROL: To guarantee the exact quantity of air required for maximum power and fuel efficiency, all air entering the engine block is directed through a single throttle valve. Following that, it enters each cylinder via a separate, lengthy intake track that is “pulse tuned” to provide air at the ideal volume and moment for optimal density and power.

DEPENDABLE STARTING: The fuel return system of the F40 and F30 reduces vapor. They provide reliable turn-key starting in both hot and cold temperatures when used in conjunction with multi-point electronic fuel injection.

Reliability and Durability

CORROSION PROTECTION: Our unique Phaze FiveTM anti-corrosive paint technique offers a robust, five-layer barrier against corrosion when combined with our proprietary alloy (YDC-30). Every four-stroke Yamaha Midrange engine comes with this protection as standard.
ADVANCED TECHNOLOGY: The Engine Control Module of the F40 and F30 connects to the Yamaha Diagnostic System software. To assist professionals in giving a thorough and precise diagnosis of your engine, this shows a selection of your engine’s previous and present operating circumstances.

Defending Against the Elements: Water entering the cowling is readily and effectively drained away by a well-proven one-piece cowling with an intake air drain system. For optimum dependability, incoming air is sent through a maze of passageways that assist catch water before it enters the engine’s intake.
CLEANER FUEL: The Yamaha optional 10-Micron Water Separating Fuel Filter is utilized in conjunction with a sizable on-engine water separating fuel filter equipped with a water sensor. This aids in removing impurities and water from the fuel before they can get to the fuel injectors and other filters on the outboard.
