highlights

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 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™

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. 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.

HELM MASTER EX COMPATIBLE

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.

features and benefits

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

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. 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.

CLEAN RIGGING

Optional for boats featuring the new and upgraded V6 Offshore with Helm Master EX Full Manoeuvrability, there is an available Integrated Helm Master Light. The light mounts directly in the rear apron of the outboard(s) rather than requiring independent lights on the transom. These clearly indicate the boat is actively in Full Manoeuvrability mode to anyone approaching from abaft (requires Helm Master EX Prop Light Kit).

EASIER FLUSHING

The engine flush hose can now be routed through a new rigging grommet inside the rigging tube, similar to XTO, which means automatic or manual on-board engine flushing systems can be used with ease (requires use of Flushing Kit). This means cleaner rigging and easier operation of one of the most important maintenance procedures for the longevity of the outboard(s). In addition, all V6 Offshore outboards still feature a built-in external flush attachment.

ENHANCED RELIABILITY AND DURABILITY

Even after a decade of proven performance, the new 4.2-litre V6 Offshore has an improved lower unit featuring new components and design features that add durability, further increasing consumer confidence.

FLEXIBLE RIGGING OPTIONS

With the new and upgraded V6 Offshore, you can choose different ignition control options on singles and twins (keyed or wireless fob). For displays, you can choose the full-function Multi- Function Display (MFD) – the CL7; the new small and thin touchscreen colour display – the CL5; or use analog gauges through use of an Analog Gauge Interface (AGI). There are even multi-function display interfaces (MFDIs) available to pipe display and control features directly to select third-party MFDs.

INCREASED COOLING CAPACITY

Yamaha V6 Offshore models come standard with dual pairs of water inlets, for increased cooling efficiency. Located on the front and both sides of the lower unit, each pair of pick-ups operate independently of each other to provide proper water flow in a wide variety of applications and conditions.

RELIABILITY AND EFFICIENCY

4.2 litres of class-leading displacement teams with individual intake and exhaust camshafts to provide more precise valve timing control with fewer moving parts than conventional rocker arm systems for increased reliability. This superior design also allows for use of 4 valves per cylinder which exchange intake and exhaust gases more efficiently for responsive power and increased fuel economy.

STRIKING NEW EXTERIOR DESIGN

Capitalizing on many styling cues from its big brother, the XTO-like appearance in pearlescent white or signature Yamaha grey now feature a colour-matched lower unit, a new one-piece top cowling with water-draining air duct molding, a new bottom cowling and apron shape and raised chrome graphics on built-in DES models only. Stunning new looks meet proven performance to compliment and complete even more premium boats.

IMPROVED TOP SPEED POTENTIAL

Compatible with Yamaha’s new Saltwater Series IITM HP propeller, faster top speed without sacrificing acceleration is possible for lighter weight V6 Offshore applications where the propeller rides fully submerged, while the built-in Shift Dampener System (SDS®) helps keeps shifting smooth and quiet.

INCREDIBLE POWER AND PERFORMANCE

As the only outboard manufacturer using a highly advanced, thermally applied plasma fusion process on the cylinder walls, Yamaha’s V6 Offshore outboards have no conventional steel cylinder sleeves, yet the cylinder walls are 60 percent harder than steel. That means larger cylinder bores for increased displacement result in more power and torque without increasing outer cylinder dimensions. It also results in significantly lighter weight, better cooling and “micro-textured” cylinder walls that dramatically reduce internal friction loss, further increase performance and enhance reliability.

OUTSTANDING FUEL ECONOMY

All air entering the engine block of each Yamaha V6 Offshore outboard is routed through a single 75mm electronically-controlled throttle valve. Working in concert with the Precision Multi-Point Fuel Injection System, these features help ensure the precise amount of air and fuel necessary for optimum power and fuel ef?ciency. The reduction in friction from the micro-textured cylinder walls further adds to this outboard’s amazing fuel economy.
