Yamaha's V MAX SHO 250 hp and 200 hp models, which have been eagerly awaited on the European market for several seasons, will be available to order from the fourth quarter of 2025. These two models, already widely distributed on other continents, mark the official introduction of the "Super High Output" range to the European offering. This range is designed for lightweight hulls, fast walk-behind fishing boats and performance-oriented RIBs.
A naturally-aspirated 4.2-litre V6 block: a compromise between torque and reliability
The two new outboard engines are based on a 60° V6 architecture, without supercharging, with a displacement of 4.2 liters. This choice guarantees available torque at low revs, ideal for heavy-duty starting or maneuvering under load. The 24 valves are operated by a double overhead camshaft (DOHC), with a TCI ignition system designed to improve engine speed stability, particularly at mid-range.
Sleeveless cylinders: weight savings and improved heat dissipation
For these two models, Yamaha has renewed its use of plasma fusion technology on the cylinder walls. By doing away with traditional steel liners, this solution reduces the overall mass of the block while promoting heat exchange. As a result, the engine boasts a better power-to-weight ratio, a decisive factor for fast hulls with high rear lift.
Complete electronic management and EFI fuel injection
The entire powertrain is based on electronic fuel injection (EFI), for fine fuel delivery and precise throttle control. This system contributes to lower fuel consumption and ensures progressive, controllable throttle response, particularly during acceleration. This type of tuning is also conducive to compatibility with integrated navigation instruments.
Power Trim & Tilt with TotalTilt?: assisted tilt over the entire stroke
Both motors are equipped with the TotalTilt system, allowing full tilt up or down at the touch of a button. This makes it easier to raise the base quickly in shallow draft situations, when launching or cleaning the propeller. It also makes it easier to adjust the boat's trim under way, with enhanced responsiveness.
Enhanced power supply: 70 A alternator as standard
Each engine is equipped with a 70-amp alternator, delivering a stabilized voltage of 12 volts. This capacity is sufficient to simultaneously power on-board equipment such as depth sounders, electric windlass and compression refrigerators. Yamaha emphasizes optimal efficiency, even at low rpm, thus limiting unnecessary engine stress at anchor.
Finishing and acoustics: a focus on perceived comfort
The manufacturer has also worked to reduce noise and vibration levels. The engine settings are designed to achieve a more subdued sound signature, which can make all the difference during long cruises or on stationary fishing boats. The V MAX SHO engine cowling features a distinctive, easily identifiable graphic identity.
