POWER AND PERFORMANCE
Superior Overall Performance
Yamaha two stroke HPDI®s feature an Engine Control Module, which regulates the HPDI® System to ensure superior power, fuel economy and reliability. Six individual sensors help the microcomputer optimize ignition timing and air/fuel mixture. Fuel is drawn through the fuel pump and vapor separator, then pressurized by the high-speed fuel pump to 700psi and sent into the fuel rails. Proven and reliable internal-opening fuel injectors provide a precise amount of fuel to each individual cylinder in a nearly atomized state, enhancing fuel distribution in the combustion chamber for maximum power and greater fuel economy.
Yamaha two stroke HPDI®s feature 76° V-block designs, which are compact and provide added torque for greater acceleration.
Max Fuel Atomization
Yamaha two stroke HPDI®s feature a High-Speed Fuel Pump that pressurizes fuel to 700 psi for maximum fuel atomization and outstanding fuel economy and performance.
Yamaha two stroke HPDI®s feature Six Individual Fuel Injectors that open internally, enhancing fuel distribution and reducing the chance of carbon build-up.
Max Fuel Economy
The proven Homogeneous Combustion Chamber Design on Yamaha two stroke HPDI®s maximizes power and fuel economy in the critical 2500-5500 RPM range.
The Vapor Separator Tank removes vapors from the fuel for smoother engine operation and increased reliability.
Yamaha offers propellers specifically designed to harness the power and maximize the performance of our 200HP HPDI® and 2.6L V MAX® HPDI® two stroke outboards. Available in aluminum, painted stainless steel or highly polished stainless steel right and left-hand rotation.
Yamaha 200HP two stroke HPDI®s feature a Multi-Charge Monitoring System that automatically monitors battery voltage and sends the alternator’s charging power to the battery that needs it most.
Yamaha HPDI® two strokes are California Air Resources Board (C.A.R.B.) Two-Star Rated for Very-Low Emissions and meet all federal EPA requirements.
RELIABILITY AND DURABILITY
A special Ion-Plated Top Piston Ring enhances durability and helps prevent oil from entering the combustion chamber. The oil bypass groove on the bottom piston ring delivers the precise amount of oil to the top ring and upper cylinder wall for even greater reliability.
A special Heat Treated Crankshaft, connecting rods, and gears enhance durability for long engine life.
Large Sacrificial Anodes in and around the engine draw corrosion away from vital, metal engine components.
Strong Forged Pistons add durability. Aluminum alloys are compressed in molds under extreme pressure, resulting in a much stronger piston on all HPDI®s.
Yamaha’s proprietary ACP-221 Paint Process provides an extra-tough, five-layer barrier against corrosion. It’s a key component of our renowned Ultimate Corrosion Protection System (UCP), which is standard on all Yamaha HPDI® two strokes.
Yamaha two stroke HPDI®s feature a stainless steel drive shaft, shift shaft, propeller shaft and steering tube for maximum corrosion resistance and long-term reliability.
Extended Engine Life
Yamaha two stroke HPDI®s feature a front-mounted Freshwater Flush Device allows you to flush the engine without starting it, for maximum convenience, durability and engine life.
Ultimate Corrosion Protection
Yamaha’s exclusive YDC-30 Alloy is one of the most corrosion-resistant base materials in the industry. Used with Yamaha’s proprietary ACP-221 Paint Process, it provides an extra-tough barrier against corrosion. They’re both key components of our renowned Ultimate Corrosion Protection System (UCP) which is featured on all Yamaha HPDI® two strokes.
Protection from Moisture
Sure-Seal Tri-Latches on all Yamaha HPDI® two strokes seal the cowl tight, keeping out water and debris.
All two stroke HPDI®s feature Precision Blend™ Oil Injection, which automatically injects the precise amount of oil based on engine load and speed.
All Yamaha 2.6L HPDI® two strokes are protected by our Two-Year Limited Warranty for pleasure use. Beyond that, Yamaha Extended Service (Y.E.S.) plans are available, for continued coverage after your factory warranty expires.
CONVENIENCE AND CONTROL
Ease of Multiple Engines
Manage multiple engines effortlessly with Yamaha’s twin binnacle controls. They feature smooth-shifting functionality and a sleek ergonomic design.
Easy Engine Flushing
Yamaha two stroke HPDI®s feature a forward-mounted Freshwater Flush Device makes it easy to completely flush the engine, in the slip or on the trailer, without running the engine.
Ample Charging Power
Yamaha two stroke HPDI®s feature a High Output Alternator to deliver an incredible 30 amps of charging power at 1,000 RPM, and up to 46 amps at approximately 3,500+ RPM. The result is plenty of charging power, even after prolonged idling or using multiple electronics while trolling at low RPMs.
Counter Rotation dramatically reduces steering torque and arm fatigue, while providing more control and acceleration in twin and triple applications. (Available on 200 2.6L HPDI®.)
Yamaha Gauges make the perfect compliment to all Yamaha engines. Our Command Link®, Multi-Function Digital and Pro Series™ gauges give you access to accurate, real-time information on all systems.
