A revised design, a retained engine block
In 2018, Yamaha launched its most powerful engine, the 425-hp V8 XTO, later joined by the 375-hp. For the 2022 season, the V6 lineup inherits the technological features of its big brothers, though there is no mention of the badge on the hood of the latter. Available in 300, 250 and 225 hp, they retain their original 4.2L engine block but adopt a new one-piece upper cowl with dual air intakes. The lower engine unit that houses the sub-base has also been modified to reduce vibration and provide a smoother ride. The oil system has also been changed for better durability over time.
New features for a smoother ride
Among the new features, the two largest powers are equipped with the Digital Electric Steering (DES, digital electric steering) for a smoother, more intuitive driving experience. For the 225 hp, DES is an option, which will be complemented by TotalTilt.
They also include the TotalTilt from Yamaha, which allows for full tilt up or down (to the trim cylinder) with a built-in lift limiter to facilitate engine handling and prevent accidental damage.
Finally, the new V6s adopt TERE (Thrust Enhancing Reverse Exhaust) for better control during reverse maneuvers. The exhaust is located above the anti-ventilation plate allowing the propeller to operate in water with no gas flow below 2500 rpm, the speed typically used during port maneuvers.
Compatible with the Helm Master EX system
These three new models are compatible with the Helm Master EX control system, which offers a wide range of piloting and navigation functions via a joystick: maneuvers, autopilot, speed limit..
Trials to discover
We had the opportunity to test these new V6 in several engine configurations and on different boats: semi-rigid, rigid hull, open hull or weekender in the bay of Mandelieu. To be discovered soon.
