Honda BF8DK3LHA 8 HP 4-Stroke Outboard Motor

Lightweight 8 HP Power, High-Output Charging, Easy One-Hand Starting & Shallow-Water Drive

The Honda BF8DK3LHA 8 HP 4-Stroke Outboard Motor is designed specifically for smaller 12–16 foot boats, delivering an impressive balance of power, portability, reliability, and fuel efficiency. At just 98 lbs., it is lighter than many conventional 8 HP outboards, making it easier to transport, install, and handle.

Powered by a 222 cc, 2-cylinder 4-stroke SOHC engine, the BF8 produces 8 HP at 5,000 RPM while maintaining Honda's reputation for quiet and efficient operation. Its advanced PGM ignition system, Auto Start Enrichment, and built-in decompression release make starting significantly easier, while the engine alert system helps protect critical components from low oil, overheating, and over-revving.

The BF8 also stands out with its fully regulated 6-amp charging system, providing up to 76 watts of electrical output. This helps maintain battery charge and power onboard electronics, even while trolling. Combined with shallow-water drive, five-position trim, a long tiller handle, and an ergonomic rounded design, the BF8 offers an ideal combination of performance and portability for smaller boats.

Key Features

Lightweight 8 HP Performance

At only 98 lbs., the BF8 provides full 8 HP performance in a remarkably portable package, making it particularly well suited for smaller boats, dinghies, and auxiliary applications.

Reliable & Efficient 4-Stroke Design

The 4-stroke engine combines Honda's renowned reliability with efficient fuel consumption and eliminates the need for fuel-oil mixing.

Easy One-Hand Starting

A built-in decompression release works with the digital ignition system to reduce the effort required to pull-start the engine by hand.

Auto Start Enrichment

The Auto Start Enrichment system functions similarly to an automatic choke, automatically adjusting the air/fuel mixture to provide easier starting and faster warm-up.

High-Output Charging System

The BF8 includes a 6-amp, 76-watt alternator with voltage regulation, providing electrical power for onboard electronics while helping maintain battery charge.

Charging at Trolling Speeds

The charging system provides 2 amps at 1,000 RPM, helping maintain battery power and operate electronics even when the engine is running at low trolling speeds.

PGM Ignition System

Honda's PGM ignition system uses a microprocessor to precisely control ignition timing during startup and throughout the engine's RPM range, helping optimize overall engine operation.

Engine Alert System

An integrated warning system helps protect the engine from potentially severe damage caused by low oil, over-revving, and overheating.

Shallow-Water Drive

The shallow-water drive system allows the motor to be tilted upward for operation in shallow areas, helping reduce the risk of lower-unit and propeller damage.

Longer Tiller Handle

The extended tiller handle provides improved control while reducing steering effort. Its lightweight composite construction contributes to durability without adding unnecessary weight.

Front-Mounted Shift Controls

The conveniently positioned shift lever allows fingertip shifting between Forward, Neutral, and Reverse, while the twist-grip throttle provides precise speed control.

Smooth Pendulum Mount System

Honda's triangulated rubber mounting system absorbs vibration and helps provide exceptionally smooth engine operation.

Starting & Fuel System

The BF8 is equipped with an easy-starting recoil system supported by Honda's PGM ignition and Auto Start Enrichment technology.

Auto Start Enrichment automatically adjusts the air/fuel mixture during startup and warm-up, helping the engine start quickly without requiring complicated manual choke adjustments.

Engine Protection

Engine Alert System

The integrated engine warning system helps protect the motor from severe damage resulting from:

• Low oil


• Over-revving


• Overheating

This added monitoring provides additional protection during operation and helps alert the operator to conditions that require attention.

Smooth & Quiet Operation

Honda's pendulum mount system uses a triangulated rubber mounting arrangement to absorb engine vibration and provide smoother operation.

The longer tiller and EZ Steer friction control also help reduce steering effort and improve operator comfort during extended use.

Lightweight & Portable Design

The BF8 weighs only 98 lbs. (44 kg) in the supplied L-type configuration. Its rounded housing and integrated carrying handle make transportation easier.
