V8 5.3-liter F350

The four stroke outboards F350 with their awesome power

Amazing Power & TorqueThe World's First 4-stroke Outboard to Use a V8 5.3 L Engine,
Revolutionizing the Offshore Outboard as We Know It.

The F350A model has pursued new potential in outboards, breaking the constraints of conventional power units for offshore applications. Its innovative and stylish form sets it apart from existing offshore outboards and hints at its high level of performance. In addition to the adoption of a V8 5.3 liter engine, which is a world-first for outboards, it also boasts the latest, original technologies. The end result is the realization of outstanding power and speed, superior durability and reliability, and a new dimension in ride comfort.

Power & Performance

Electronic single throttle/ Long intake manifold

The electronically controlled single throttle and long intake manifold with its changed intake structure provides the optimum amount of air to the combustion chambers, enabling the engine to produce maximum torque and power.

VCT: Variable camshaft timing

This system regulates intake valve open/close timing according to engine load. It heightens air intake efficiency and increases torque in the low to mid engine speed range.

Reliability & Durability

Compact in-bank exhaust

The in-bank exhaust system helps enhance engine performance by sending exhaust gases out more efficiently and reducing exhaust pressure.

Oversized strong mounting bracket

The bracket and mount system with forged parts and oversized mounting bracket provide plenty of durability and help protect the motor from shocks during offshore cruising in rough waters.

Durable lower unit bearings

An engine with as much power and torque as this needs lower unit bearings and bearing surfaces that stand up to the test. Yamaha has not only changed the type of bearings and / or increased their size, but also hardened the surfaces on which they ride, for increased reliability.


Variable trolling speed

Allows the adjustment of desired trolling speed at every 50 r/min between 600 and 1000 r/min.

Digital electronic throttle & shift

liminates remote control cable. Ensures smooth throttle and sure shifting for reliable operability.
