1.0-Liter Four-Cylinder Engine
The Yamaha F70 uses a 1.0-liter inline-four engine with electronic fuel injection.
Its 16-valve design and single-overhead-camshaft configuration are intended to support responsive performance and efficient operation in a lightweight package.
Yamaha’s electronic fuel injection system helps deliver fuel to the engine according to operating requirements, supporting consistent running performance across a range of boating conditions.
Lightweight 70HP Performance
The Yamaha F70 weighs approximately 253 pounds, making it a practical option for compatible boats where weight and balance are important considerations.
Its lightweight construction combined with 70 horsepower provides a useful balance of performance and maneuverability for fishing and recreational boating.
Actual performance, acceleration, and top speed depend on the vessel’s hull design, propeller, passenger and equipment load, water conditions, and engine setup.
20-Inch Shaft Configuration
The Yamaha F70 features a 20-inch shaft configuration.
Selecting the correct shaft length is important for proper engine mounting and operation. Customers should verify their vessel’s transom height and manufacturer’s recommended shaft length before ordering.
15-Amp Charging System
The Yamaha F70 features a 15-amp alternator output at wide-open throttle, providing charging capability for the boat’s battery and compatible onboard electrical accessories.
This is useful for compatible fishing and recreational boats equipped with basic marine electronics, navigation equipment, and other electrical accessories. Actual charging output varies with engine speed and electrical load.
Optional Variable Trolling RPM
The Variable Trolling RPM Switch (VTS) is available as an optional feature, depending on the selected rigging and equipment configuration.
This feature allows anglers to make controlled trolling-speed adjustments, helping maintain a suitable pace for different fishing conditions.
Customers should confirm the compatibility and additional equipment required for this option before purchase.
Remote Mechanical Controls and Power Trim & Tilt
The Yamaha F70LB, F70LB2, and F70LB3 are listed with remote mechanical controls and power trim and tilt.
Remote controls allow operation from a compatible helm, while power trim and tilt provides convenient adjustment of the engine’s position during operation, launching, and storage.
Customers should confirm the required remote-control box, cables, steering equipment, gauges, propeller, and other rigging components for their specific boat before installation.
Three Available Colors
The Yamaha F70 70HP is available in three finishes:
Yamaha Gray – F70LB: Traditional Yamaha appearance.
Pearl White – F70LB2: A clean white finish for boats with a light or modern color scheme.
Matte Brown – F70LB3: A distinctive matte finish for customers looking for an alternative to traditional outboard colors.
Color selection should be made when ordering because each finish has a corresponding model code and MSRP.
