Honda's new 75/90HP EFI Engines

Product catalog summary

Overview
Honda's 75/90 hp EFI engines incorporate advanced technology for mid-size marine engines, featuring VTEC racing technology for power and lean burn technology for fuel efficiency. These engines are known for their durability and quiet operation.

Specifications
The engines are 4-stroke SOHC with 4 cylinders and a displacement of 1496cc. They have a full throttle RPM range of 5300-6300 for 90HP and 5000-6000 for 75HP. The engines use PGM-FI fuel delivery and have a microcomputer programmed ignition system.

Features

Programmed Electronic Fuel Injection: Ensures precise fuel/air delivery for easy starts and efficient throttle response.
Torsion Dampener: Improves handling by lowering the center of gravity.
Engine Alert System: Provides alerts for overheating, low oil pressure, and over-revving.
Corrosion Protection System: Utilizes a multi-layered paint process and stainless steel technology for enhanced protection.
Lean Burn Control: Increases fuel efficiency by operating on a leaner air/fuel mixture.
High Performance Gearcase: Reduces drag and increases acceleration and top speed.
Superior Battery Charging: Offers 35 amps of charging power, significantly more than competitors.

Comparative Advantages
Compared to competitors like Yamaha, Mercury, and Suzuki, Honda's engines are lighter, offer more battery charging power, and include features like the BlasT system and lean burn control that competitors lack.

Conclusion
Honda's 75/90 hp EFI engines provide a combination of advanced technology, efficiency, and reliability, making them a superior choice in the mid-size marine engine market.

lean Burn Control Increases fuel efficiency by allowing combustion to operate on a leaner air/fuel mixture. At cruising speed, this engine runs on 20%less fuel*than others in its class. ■ BATTERY CHARGING AMPS Mode Consumption RACING TECHNOLOGY VTEC synchronizes the lift and duration of the intake valves both at low rpm and at high rpm. This yields a longer, flatter torque curve which means max power at every speed. Superior Battery Charging There's always plenty of electric power with Honda's exclusive neodymium magnet flywheel.
