2023　SETC High Quality Paper Award

Awarded: Development of Lightweight Oil Catch Tank Produced by Laser Powder Bed Fusion
Recipient(s): Keita Watanabe, Hirotaka Kurita, Shinya Iwasaki
Materials Division, Manufacturing Technology Center

2023　SETC High Quality Presentation Award

Awarded: Effect of Impurity Elements in Recycled Ingots on Seizure Properties of Die-Cast Cylinders made of Hypereutectic Al-Si Alloy
Recipient(s): Atsushi Owada, Takaharu Suzuki
Materials Division, Manufacturing Technology Center

2020　IBEX Innovation Award

Awarded: Phase Angle Control Charging System; This high-output alternator system for outboard motors enables use of gyro stabilizers, air conditioning, sound systems, console area electronics, etc., without use of a generator by providing up to 96 amperes of electricity (net value per outboard) even when idling.

2018　IBEX Innovation Award

Awarded: F425A; The F425A employs a 5,559cc V8 engine producing 425 hp and is the first 4-stroke outboard to use gasoline direct injection to spray fuel at high pressure and high precision directly into each combustion chamber. It also features an integrated electric steering system, which eliminates the need for cables or hydraulic lines.

2017　IBEX Innovation Awards

Awarded: F25G; The F25G uses a 432cc in-line 2-cylinder engine and is approx. 20 kg lighter than its predecessor, a weight reduction that makes it the lightest offering in the 25 hp 4-stroke outboard class. Its other features include a battery-less fuel injection system for easy engine starts.

2014　SETC High Quality Paper Award

Awarded: Friction Measurement of Al-17%Si Monolithic Cylinder with using Newly Developed Floating Liner Device
Recipient(s): Tatsuhiko Sato
Motor Sports Development Division, Technology Center

Hirotaka Kurita, et al.
Materials Division, Component Section, Engine Unit

2013　SETC High Quality Paper Award

Awarded: Reduced-Order Modeling of Intake Air Dynamics in Single-Cylinder Four-Stroke Engine
Recipient(s): Shun-ichi Akama, Yasunori Murayama, Shigeho Sakoda
Fundamental Technology Research Division, Research & Development Section, Technology Center

2013　IBEX Innovation Award

Awarded: F200 and VF150 VMAX SHO; F200
This 4-stroke 2,785cc inline 4-cylinder 200 hp outboard motor achieved the lightest weight in its class (in February 2013) while earning the highest-possible three-star rating for ultra-low emissions based on the 2008 California Air Resources Board (CARB) regulations.; VF150 VMAX SHO
This 4-stroke 2,785cc inline 4-cylinder 150 hp outboard motor achieved top speed and acceleration rivaling that of a 2-stroke and a lightweight design thanks to its 16-valve, DOHC layout with Variable Cam Timing (VCT), electronically controlled fuel injection and other technologies.

2011　SETC Best Paper Award/ High Quality Paper Award

Awarded: Influence of Injection and Flame Propagation on Combustion in Motorcycle Engine – Investigation by Visualization Technique –
Recipient(s): Miki Yumoto, Kazuhiro Goto, Shouichi Kato, Minoru Iida
Powertrain Technology Research Division, Research & Development Section, Technology Center

2010　SETC High Quality Paper Award

Awarded: Analysis of Port Injected Fuel Spray Under Cross Wind Using 2-D Measurement Techniques
Recipient(s): Minoru Iida, et al.
Powertrain Technology Research Division, Research & Development Section, Technology Center

2010　IBEX Innovation Award

Awarded: VF250 VMAX SHO; This 4-stroke 4,169cc V6 250 hp outboard motor was the first to employ large diameter sleeveless cylinders, which provide reduced weight and increased heat and wear resistance through the use of thermal spray technology.

2009　SETC High Quality Paper Award/High Quality Presentation Award

Awarded: Fuel Film Behavior Analysis Using Simulated Intake Port
Recipient(s): Minoru Iida, Keiichi Yoshikawa, et al.
Powertrain Technology Research Division, Research & Development Section, Technology Center

2007　SETC Best Paper Award

Awarded: Fuel Behavior Model-Based Injection Control for Motorcycle Port-Injection Gasoline Engines
Recipient(s): Masaki Torigoshi
Advanced Technology Research Division, Research & Development Operations

Hiroki Tanabe, Shigeho Sakoda
Advanced System Research Division, Research & Development Operations

2007　SETC Best Paper Award

Awarded: Determination of Operating Ranges of Marine Engines
Recipient(s): Daniel Jeffery Ostrosky, et al.

2007　IBEX Innovation Award

Awarded: F350A; The F350A was the first commercially available outboard motor powered by a V8 engine, and it had the highest displacement in the world (in February 2007) at 5,330cc, producing a maximum 350 hp. Among its features was the ability to synchronize rpm with other motors in multi-rig formats (up to three total).

2000　Boating Week Innovation Award

Awarded: F225; The F225 featured an internal layout which reversed the configuration of the air intake and exhaust systems to create an “in-bank exhaust system,” a first for an outboard motor. Compared to other models with similar horsepower, the 4-stroke F225 was significantly lighter and more compact.

1999　MotorBoating and Sailing Award

Awarded: F100; This 1,596cc inline 4-cylinder 100 hp 4-stroke outboard motor featured the world’s first 16-valve DOHC engine.

1999　IMTEC Innovation Award

Awarded: High Pressure Direct Injection (HPDI); Compared to conventional direct-injection systems of the time that used pressures of around 20 bar (290 psi), this fuel injection system for outboard motors made it possible to inject fuel at much higher pressures of 50 bar (725 psi). By reducing the injection spray into finer particles, it improved combustion efficiency, thus lowering fuel consumption and producing cleaner emissions.

1990　FISITA World Automotive Congress Outstanding Paper Award

Awarded: Traction Drive CVT for Motorcycle
Recipient(s): Yasushi Ichihara
Motorcycle Center, Testing Group

1985　Tomizuka Prize

Awarded: R&D and practicalization of an exhaust timing control system for high-performance 2-stroke engines (Yamaha Power Valve System)
Recipient(s): Masayasu Mizoguchi
Motor Sports Development Operations

1984　Japan Society of Mechanical Engineers Medal

Awarded: LDV Measurements of Pipe Flows in a Small-Two-Cycle Spark-Ignition Engine
Recipient(s): Noritaka Matsuo
Research Division

Yoshio Hirano, et al.
Power Products Business Unit

1964　Auto & Motor Sport Magazine Annual Trophy

Awarded: YG-1; This motorcycle’s 2-stroke 75cc 6.5 hp single-cylinder engine featured a cutting-edge rotary disc valve intake and was mounted in a lightweight and compact 70 kg chassis, resulting in outstanding performance and reliability.
