Core Features of Your Yamaha F90LB 90 HP Outboard

Propeller-Driven Performance

The F90LB utilizes a conventional propeller-driven lower unit. This design provides efficient propulsion for a wide range of planing and displacement hull boats. It offers excellent top-end speed and versatile performance for fishing, cruising, and watersports.

Robust 1.8-Liter In-Line 4 Engine

The F90LB features a 1.8-liter (1832cc), In-Line 4-cylinder, single-overhead-camshaft (SOHC) engine. This design, therefore, provides a compact, lightweight, and space-saving powerhouse. It delivers strong low-end and mid-range torque, resulting in quick acceleration and responsive handling.

Electronic Fuel Injection (EFI)

The F90LB utilizes Electronic Fuel Injection. This advanced system ensures precise fuel delivery. It provides easy starts, smooth idling, and outstanding fuel efficiency across all RPMs. Furthermore, EFI minimizes emissions and reduces maintenance requirements.

Lightweight and Compact Design

Weighing approximately 353 pounds (160 kg), the F90LB offers an impressive power-to-weight ratio for a 90 HP outboard. This lighter weight, consequently, reduces transom stress and enhances boat performance.

Long (20-inch) Shaft

The “LB” in F90LB specifies a long 20-inch shaft length and indicates a remote mechanical control. This makes it ideal for boats with standard transom heights. It ensures the propeller remains sufficiently submerged for optimal performance, even in choppy water or when running at high speeds.

Electric Start

The F90LB includes electric start for convenient push-button ignition. This provides effortless starting, allowing quick water access.

Power Trim and Tilt

The “B” in F90LB indicates full Power Trim and Tilt. This essential feature lets you conveniently adjust the engine’s angle with a simple button press. Indeed, this is perfect for shallow water maneuvering, trailering, or fine-tuning the boat’s running attitude for optimal performance and fuel economy. It offers a wide trim range, including negative trim, for quicker planing.

Remote Mechanical Control

The F90LB operates via remote mechanical control. Specifically, this connects to a control box at your boat’s helm or console. This provides precise throttle, shift, and steering control for a more comfortable and integrated boating experience.

High Output Alternator

Equipped with a 35-amp alternator, the F90LB generates ample power. It keeps your boat’s battery charged. Furthermore, it runs essential electronics, lights, and other accessories, even during extended idling or slow speeds.

Variable Trolling RPM Switch (VTS®)

The F90LB offers the optional Variable Trolling RPM Switch (VTS®). This allows anglers, for instance, to fine-tune trolling speeds in precise 50 RPM increments, from 550 to 1000 RPM. This is highly beneficial for various fishing techniques. You can access it via a compatible gauge or remote switch.

Durable and Reliable Construction

Yamaha built the F90LB with legendary quality. It features a robust design. This includes, for example, Electronic Fuel Injection, a microcomputer-controlled ignition, and a wet sump lubrication system. Yamaha’s exclusive Phaze Five™ anti-corrosive paint system provides a tough, five-layer barrier against corrosion. Yamaha engineered it to withstand rigorous use. It provides years of trouble-free operation.

Freshwater Flushing Device

A convenient freshwater flushing device is integrated into the engine. This allows you to easily flush salt and debris from the cooling passages without running the engine. Consequently, this significantly extends your outboard’s lifespan, especially after saltwater use.
