Yamaha F40LA Outboard Motor

20-Inch Shaft | Remote Control | Electric Start | Power Trim And Tilt | Yamaha Gray

The Yamaha F40LA is a 40 hp Yamaha outboard motor designed for aluminum fishing boats, skiffs, small center consoles, bay boats, and compatible utility boats. This Yamaha outboard engine combines a 20-inch shaft, remote control, electric start, Electronic Fuel Injection, and power trim and tilt in a configuration built for compatible boats rated for 40 horsepower.

This configuration is designed for a compatible remote helm, control box, steering system, cables, and rigging. Power trim and tilt provides powered running-angle adjustment, shallow-water positioning, and easier trailering. Before ordering, confirm the boat’s horsepower rating, transom height, shaft requirement, steering setup, battery and rigging needs, propeller choice, and typical passenger and gear load.

Compare before ordering: Use the Model Comparison Guide above the model selector to review both Yamaha F40 configurations. The F40LEHA uses tiller steering and manual tilt, while the F40LA uses remote control and power trim and tilt.

Best Boats for This 40 HP Yamaha Outboard

Boat type	Fit for F40LA	Buyer guidance
Aluminum fishing boats	Strong fit	Remote steering and power trim and tilt suit many console-equipped fishing layouts.
Skiffs	Strong fit	A practical match when the hull uses a 20-inch transom and remote helm.
Small center consoles	Strong fit	Remote controls and powered trim support everyday cruising and fishing.
Bay boats	Possible	Confirm the hull rating, total load, expected water conditions, and performance requirements.
Utility boats	Good fit	Suitable when the boat is already configured for remote steering and electric start.
Large or heavy boats	Usually not enough power	Consider a larger Yamaha outboard for heavier hulls, greater loads, or offshore use.

A 40 hp outboard is commonly chosen when boaters need more power than a 25 hp portable motor while retaining a manageable engine for compatible fishing, utility, and recreational boats. Never exceed the boat manufacturer’s maximum horsepower rating.

20-Inch Long-Shaft and Transom Compatibility

The Yamaha F40LA has a 20-inch shaft, commonly called a long-shaft outboard. It is intended for boats with compatible 20-inch transoms. Measure the transom and confirm the shaft length required by the boat manufacturer before ordering; shaft length should not be selected from boat length alone.

Yamaha F40LEHA vs. F40LA: What Is the Difference?

Model	Steering	Tilt / trim	Best for
Yamaha F40LEHA	Tiller handle	Manual tilt	Direct tiller control and a simpler manual-tilt setup
Yamaha F40LA	Remote control	Power trim and tilt	Console-steered boats and powered trim adjustment

Choose the Yamaha F40LEHA when the boat is set up for tiller steering and a manual-tilt configuration. Choose the Yamaha F40LA when the boat uses remote steering and requires power trim and tilt. Confirm current product specifications, propeller requirements, controls, battery, steering, and installation needs before purchasing.

What to Check Before Buying This 40 HP Yamaha Boat Motor

• Horsepower rating: Confirm that the boat is rated for a 40 hp outboard.
• Shaft length: Verify that the boat requires a 20-inch long-shaft motor.
• Steering: Confirm compatibility with remote control.
• Starting system: Plan for the battery, key switch, wiring, and related requirements of electric start.
• Tilt or trim: This configuration uses power trim and tilt.
• Boat load: Include passengers, fuel, batteries, fishing equipment, coolers, and typical operating conditions.
• Propeller and rigging: Confirm the correct propeller, mounting hardware, controls, cables, steering components, and installation parts.
• Maintenance: Plan for engine oil, filters, gear lube, flushing, fuel care, break-in service, and scheduled maintenance.

What Affects the Total Yamaha F40 Setup Cost?

The total cost can vary by selected model, steering configuration, tilt system, propeller, battery, controls, cables, gauges, freight, dealer preparation, installation, extended warranty, and current availability. Compare the complete setup rather than only the engine price.

Support the Yamaha F40LA After Purchase

Confirm the correct Yamaha outboard propeller, Yamaha outboard service kit, Yamalube four-stroke marine oil, and Yamaha outboard filters for the exact model. Review compatible Yamaha outboard controls, steering components, cables, and electrical rigging.

Use Yamaha service and owner’s manuals, the Yamaha outboard service schedule, and Yamaha outboard engine schematics for model-specific maintenance and parts identification. To compare nearby horsepower and configuration options, browse Yamaha FourStroke 30–115 hp midrange outboards.
