Honda 10 HP Electric Start Long Shaft Outboard Marine Engine

The Honda BF 10 DK2 LHSU is a 4-stroke outboard marine engine designed for inflatable boats, small aluminum boats, and sailboat auxiliary engine applications that require a long shaft, featuring a 10 HP / 7.4 kW and 222 cc 2-cylinder OHC water-cooled engine. Its 2-cylinder OHC structure provides smoother power delivery, less vibration, and quieter operation compared to single-cylinder alternatives.

BF 10 DK2 LHSU Engine Technology: The 2-Cylinder OHC Advantage

The 222 cc 2-cylinder OHC (Overhead Camshaft) engine reduces vibration and balances power output with a more frequent firing interval. The water-cooled system ensures stable operating temperatures during prolonged use. With a weight of 48 KG, it offers a balanced power-to-weight ratio in the long shaft category.

• 2-Cylinder OHC Engine (222 cc): Smoother power delivery and less vibration compared to single-cylinder alternatives — a comfort difference on long voyages
• Long Shaft (508 mm (20")): Perfect fit for boat transom heights requiring a long shaft — propeller operates at optimum depth
• F–N–R Gear System: Forward, neutral, and reverse — full control in confined spaces, at docks, and during marina maneuvers; a critical advantage in sailboat maneuvers
• Manual Start with Electric Starter: Easy engagement with electric assistance; a reliable mechanical alternative to a battery-dependent full electric system
• Manual Trim: Manual adjustment of transom angle — simple and reliable mechanical structure, independent of electricity
• 12-Liter External Tank Inlet: Range determined by user needs — comfort for long routes with external tank connection

Long Shaft — Which Boat Type Is It Suitable For?

The long shaft (508 mm / 20") is suitable for the vast majority of inflatable boats, aluminum fishing boats, and small fiberglass boat models. It also fits standard transom heights for sailboat auxiliary engine use.

Technical Specifications

Who Is This Engine For?

• Inflatable boat and small aluminum boat users: The 2-cylinder OHC structure and F–N–R gear make it the most balanced 10 HP option in this segment
• Fishing and lake use: Quiet operation of the water-cooled 4-stroke allows for long sessions without scaring fish
• Sailboat auxiliary engine: Quiet 10 HP power with F–N–R control for marina maneuvers and short passages
• Those seeking a backup engine: A portable safety solution in addition to the main engine — easily transported at 48 KG

Maintenance and Longevity

Impeller inspection for the water-cooled system should be performed every 100 hours or two seasons. For saltwater use, freshwater flushing is mandatory after every use. The 4-stroke design requires oil changes — we recommend an oil change after the first 50 hours.

Frequently Asked Questions

Which inflatable boats is the Honda BF 10 DK2 compatible with?

It is suitable for all inflatable boat and aluminum boat models with a transom height of 508 mm (20"). It provides the most efficient use for inflatable boats ranging from 2.5–4 meters in length. Please verify your boat's transom height from the manufacturer's brochure.

How much better is the 2-cylinder OHC engine compared to the BF 6 single-cylinder engine?

The 2-cylinder OHC structure of the BF 10 provides less vibration and smoother power delivery due to a more frequent firing interval compared to the BF 6's single-cylinder OHV engine. The difference in displacement, 222 cc vs 127 cc, offers a noticeable advantage for carrying loads and against headwinds.

How does the Manual Start with Electric Starter system work?

The electric starter system engages the starter motor with a turn of the key. The battery load is lower compared to a fully electric system. A manual pull-start is available as a backup — allowing for safe starting if the battery is dead.

Which inflatable boat brands are compatible with the BF 10 DK2 LHSU?

Thanks to Honda's universal transom clamp system, Honda outboard motors are compatible with the vast majority of inflatable boats from brands like Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local manufacturers. The only criteria are your boat's 508 mm (20") transom height and the manufacturer-approved maximum engine power.
