Yamaha 350 HP Outboard for Sale: The F350 V8

When the Yamaha F350 arrived, it changed what boaters expected from an outboard. A 5.3 litre V8 four stroke, it gave large offshore boats the kind of smooth, torquey power that previously needed inboard engines. It became the engine of choice on big centre consoles and sportfishers, usually in twins, triples or quads. Here is every Yamaha 350 HP outboard for sale in our stock.

Standard rotation

Counter rotation

F is standard rotation, LF is counter rotation, X is the 25 inch shaft and U the 30 inch shaft. Versions ending in 2 are a later variant; check each product page for details.

Why the F350?

V8 torque

A large V8 delivers massive low end torque, pulling heavy offshore boats onto plane with full tanks, crew and gear.

Smooth, quiet running

Eight cylinders run with very little vibration, which makes long offshore runs far more comfortable.

Built for multi engine rigs

The F350 was designed for twin, triple and quad installations, with digital controls that keep multiple engines in sync.

Boats That Suit a Yamaha 350

  • Offshore centre consoles of 10 to 13 metres in twin or triple setups.
  • Sportfishing boats and express cruisers.
  • Large catamarans and commercial boats needing big, reliable power.
  • Repowers of older F350 installations, where matching engines simplifies rigging.

Planning a Multi Engine Installation

In a twin rig, use one F and one LF. In a triple, a common setup is two outer engines in opposite rotation with a standard rotation centre engine. Match shaft lengths across all engines. The F350 uses Yamaha's digital electronic controls, so plan for compatible controls, harnesses and gauges, plus hydraulic steering sized for the load, heavy duty batteries and high capacity fuel filtration.

25 or 30 Inch Shaft?

X (25 inch) and U (30 inch) are both common. Large offshore boats with high transoms and multi engine setups often use U. Measure carefully, especially when replacing engines on a bracket.

Considering the XTO?

Yamaha's newer XTO Offshore 425 builds on the V8 idea with more power and integrated electric steering. If you are not matching existing F350s, it is worth comparing.

Care for Big V8s

Engines of this size reward careful maintenance. Flush every engine after salt water use, change engine oil, filters and gear oil at the hours in the manual, inspect anodes, thermostats and water pump impellers, and keep fuel clean with high capacity water separators. On multi engine boats, service all engines together so their hours and condition stay matched. Run each engine regularly, even when the boat is idle for weeks, and keep batteries fully charged.
