Yamaha 90hp Outboard Engine

Yamaha 90hp Outboard Engine

The Yamaha 90hp Outboard Engine is one of the most trusted and powerful midrange four-stroke motors on the market today, designed specifically for anglers and boaters who require a blend of speed, efficiency, and reliability. Whether you’re trolling inshore waters or powering a multi-species fishing boat across rough seas, this engine delivers performance that elevates your boating experience.

Advanced Engine Design for Superior Performance

At the heart of the F90 is a 1.8-liter inline 4-cylinder engine featuring a single overhead camshaft (SOHC) design with four valves per cylinder. This combination boosts volumetric efficiency, meaning the engine breathes better, creating more power while remaining lightweight. The result is a motor that offers excellent torque and acceleration, ideal for boats ranging from 20 to 25 feet in length.

Unlike older models, the F90 utilizes Electronic Fuel Injection (EFI) technology. EFI delivers fuel more precisely than carbureted systems, improving throttle response and fuel economy, while reducing emissions—making it both a powerful and environmentally responsible choice.

Precise Control with Variable Trolling RPM Switch (VTS®)

One of Yamaha’s standout innovations on the F90 is the Variable Trolling RPM Switch (VTS®). Anglers will appreciate the ability to adjust trolling speeds in 50 RPM increments anywhere from 550 to 1000 RPM. This fine control allows you to match the motor speed perfectly to the fishing conditions or bait presentation, even enabling sub-idle trolling speeds, which are essential when working in sensitive or shallow waters.

Enhanced Electrical System with High Output Alternator

The F90 features a three-phase alternator capable of producing up to 35 amps of power—40% more output than previous designs. This high-capacity electrical system ensures your batteries stay charged, even when running multiple accessories like fish finders, lights, or live wells.

Durability and Maintenance Made Easy

Yamaha designed the F90 with long engine life and easy maintenance in mind. A built-in freshwater flush device lets you rinse salt, dirt, and debris from the cooling system without running the engine—great for preserving performance and preventing corrosion after a day on the water. Additionally, the F90’s power trim and tilt system allows you to adjust the engine’s angle for optimal performance and protection against shallow hazards.

Ergonomics and Handling

The F90 is engineered for smooth handling, featuring remote mechanical steering with a 20-inch shaft—perfect for a variety of mid-sized boats. The motor’s weight of 353 lbs strikes a balance between stability and agility, helping maintain a comfortable, controlled ride on the water.

Yamaha’s Trusted 3-Year Warranty

Yamaha backs this engine with a comprehensive 3-year warranty, underscoring their confidence in the product’s quality and durability. This warranty protects your investment, offering peace of mind whether you’re fishing recreationally or relying on your motor for commercial use.
