Product information

Whether you're a recreational boat owner or a busy professional, choose the F350 to help you get more out of your boat.

Like every engine in the Yamaha range, it uses the very latest Yamaha marine technologies. Revolutionary engine layouts and ingenious intake and exhaust systems offer you supreme efficiency, aided by micro-computer controls which monitor every aspect of performance, from fuel mixture and combustion efficiency to maintenance scheduling.
Without compromising on power, performance or usability, our specially designed marine engines also help preserve the environment through the use of pioneering clean-burn technologies.

5 Years warranty5.3 litre 60º V8, DOHC with VCT

This powerful V8 engine incorporates a sophisticated EFI system, lightweight forged pistons and 4 over-sized valves per cylinder. Thanks to the special Dual Battery Charging System – which charges two batteries simultaneously – you’ll always have plenty of power to start the engine, even after long periods of idling at low RPM ,

Free flexible rigging kitDigital Network II

Boaters today expect clear, accurate engine data – and the new Multifunction Colour Gauge delivers. Only compatible with Yamaha’s new rigging system, its 5-inch full colour, high-resolution LCD can be configured to display multiple combinations of information. There’s even a special screen that can be set to monitor the Variable Trolling RPM mode.

Why choose yamahaVariable Camshaft Timing (VCT)

VCT precisely regulates the timing of camshaft intake, increasing combustion efficiency across all RPM ranges. Precise valve control delivers maximum torque, especially in the 2000-3500 RPM range, allowing large boats to get onto the plane easily – and get away fast.

Micro-computer ECM (Engine Control Module)

A reliable micro-computer is the 'brain' of your engine. By constantly monitoring all data inputs and settings, it helps ensure smooth running and optimised ignition timings – as well as activating warning and protection systems. A handy computer access port lets authorised Yamaha dealers easily diagnose any problems.

Counter-rotating propeller model

Digital network gaugesA standard twin-engine installation (with both propellers turning clockwise) pulls the boat towards the port side, making steering difficult, especially at higher speeds. The F350 is available with a counter-rotating propeller, offering perfect ‘neutral helm’ control when fitted alongside a standard model.

Dual In-bank™ exhaust and forged motor mounts

The innovative exhaust system, routed centrally between the cylinder banks, results in a more compact and even lighter engine design – for improved efficiency and performance. Of course, everything is built to be tough – forged aluminium mounts and an oversized mounting bracket add extra strength and banish noise and vibration.

PrimeStart™

You'll start the mighty F350 as easily as a car – even from cold. Exclusive to Yamaha, the PrimeStart™ system ensures that the engine fires first time, every time.

Wide Range Power Trim & Tilt

Discover the versatility and power of a Yamaha engine. Quick response, via push-button control, makes trim and tilt adjustments swift, smooth and easy. Experience a trim range of -4° to +16°, with negative settings, all geared to improve acceleration and bring the boat onto the plane quickly.
