2023 Yamaha Marine F300

Yamaha's next-generation 4.2-litre F300 Offshore outboard combines a high performance, big block V6 featuring outstanding power and fuel efficiency with the availability of Yamaha-exclusive built-in Digital Electric Steering and Thrust Enhancing Reverse Exhaust system.

BUILT-IN DIGITAL ELECTRIC STEERING

The same smooth, fast and precise Digital Electric Steering (DES) introduced on the XTO Offshore is now built-in to F300 and F250 V6 variants. The latest boat steering technology provides smooth, fast steering and, unlike some conventional steering systems, draws battery amperage only when actively in use.

THRUST ENHANCING REVERSE EXHAUST

Thrust Enhancing Reverse Exhaust keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm when in reverse. This means the prop bites only clean water, resulting in outstanding reverse thrust and control to back down on fish. It’s especially effective when combined with the fast precision of Digital Electric Steering and Helm Master EX Full Manoeuvrability, which is helpful around docks and confined spaces.

TOTALTILT(TM)

Yamaha’s exclusive TotalTilt(TM) function allows complete tilt up from any position with a simple double push of the “UP” trim/tilt button, or full tilt down (until trim ram contact) by the same double push of the “DOWN” trim/tilt button. There’s also a new built-in integrated tilt limiter to help prevent inadvertent damage. Plus, built-in DES models tilt higher out of the water than previous models, which helps lessen the potential for corrosion.

Features may include:

SMOOTH, PRECISE DIGITAL ELECTRIC STEERING (DES)
  • The same smooth, fast, and precise Digital Electric Steering that was introduced on the XTO Offshore is now built-in to F300 and F250 variants. DEC models can be equipped with the new bolt-on Helm Master® EX Digital Electric Steering as well. The result is significantly easier rigging and an uncluttered bilge - with no steering pumps, hoses, hydraulic lines or connections, no bleeding procedure, less complexity and straightforward serviceability. Both use the latest in boat steering technology to provide smooth, fast steering and, unlike some conventional steering systems, draw battery amperage only when actively in use.
STRONGER REVERSE AND LOW-SPEED MANOEUVRING
  • Thrust Enhancing Reverse Exhaust (TERE) keeps exhaust bubbles above the anti-ventilation plate and out of the propeller below 2500 rpm when in reverse. This means the prop bites only clean water, resulting in outstanding reverse thrust and control to back down on fish. It’s especially effective when combined with the fast precision of Digital Electric Steering and the Helm Master EX Full Manoeuvrability joystick – very helpful around docks and confined spaces.
MORE FLEXIBILITY, MORE CONTROL
  • The new Helm Master EX DEC control brings modern amenities like speed control, trim assist and station selection to all DEC installations, in addition to useful convenience features like single-lever operation and centre engine only to multi-engine DEC applications.
FASTER, EASIER ENGINE TILTING
  • Yamaha’s exclusive TotalTilt™ function allows complete tilt up from any position with a simple double-push of the “UP” trim/tilt button, or full tilt down (until trim ram contact) by the same double push of the “DOWN” trim/tilt button. For safety, a warning horn will sound just before and during these operations. Movement and the horn can be stopped anywhere in between by pressing the tilt button again. No more holding the trim button makes for effortless trailering and convenience when complete up or down tilt is desired.
