Honda 10 HP Electric Start Short Shaft Outboard Marine Engine

The Honda BF 10 DK2 SHSU is a 4-stroke outboard marine engine designed for inflatable boats, small aluminum boats, and sailboat auxiliary motor applications requiring a short shaft. It features a 10 HP / 7.4 kW, 222 cc 2-cylinder OHC water-cooled engine. The 2-cylinder OHC configuration offers smoother power delivery, less vibration, and quieter operation compared to single-cylinder alternatives.

BF 10 DK2 SHSU Engine Technology: 2-Cylinder OHC Advantage

The 222 cc 2-cylinder OHC (Overhead Camshaft) engine reduces vibration and balances power output with more frequent ignition. The water-cooled system ensures stable operating temperatures during extended use. At 45.5 KG, it offers a balanced power-to-weight ratio in the short 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
• Short Shaft (381 mm (15")): Perfect fit for boat transom heights requiring a short shaft — propeller operates at optimum depth
• F–N–R Gear System: Forward, neutral, and reverse — full control for tight spaces, dock, and marina maneuvers; critical advantage for sailboat maneuvers
• Electric Start with Manual Backup: Easy engagement with electric assistance; reliable mechanical alternative to fully electric systems dependent on a battery
• Manual Trim: Manual adjustment of the transom angle — simple and reliable mechanical structure, independent of electricity
• 12-Liter External Tank Connection: Range determined by user needs — comfort for long routes with external tank connection

Short Shaft — Suitable for Which Boat Type?

A short shaft (381 mm / 15") is suitable for standard inflatable boats and small aluminum boat transom heights. It should not be confused with the long shaft model — an incorrect choice will prevent the propeller from reaching the correct depth.

Technical Specifications

Who is This Engine For?

• Inflatable boat and small aluminum boat users: 2-cylinder OHC structure and F–N–R gear, 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: F–N–R controlled, quiet 10 HP power for marina maneuvers and short passages
• Those seeking a backup engine: Portable safety solution supplementing the main engine — easily transported at 45.5 KG

Maintenance and Longevity

The impeller of the water-cooled system should be checked every 100 hours or every two seasons. After each use in saltwater, freshwater flushing is mandatory. The 4-stroke design requires oil changes — we recommend an oil change after the first 50 hours.

Frequently Asked Questions

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

It is suitable for all inflatable boat and aluminum boat models with a transom height of 381 mm (15"). It provides the most efficient use for inflatable boats ranging from 2.5–4 meters in length. Confirm 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 BF 10's 2-cylinder OHC structure provides less vibration and smoother power delivery with more frequent ignition intervals compared to the BF 6's single-cylinder OHV engine. The 222 cc versus 127 cc displacement difference offers a noticeable advantage in carrying capacity and against headwinds.

How does the Electric Start with Manual Backup system work?

The electric start system engages the starter motor with a turn of the key. The battery load is lower than a fully electric system. A rope-pull manual backup is available — allowing for reliable starting if the battery dies.

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

Honda outboard motors are compatible with the vast majority of Zodiac, Ribeye, Highfield, Bombard, Sea Eagle, and local brand inflatable boats thanks to their universal transom clamp system. The only criteria are your boat's 381 mm (15") transom height and the manufacturer-approved maximum engine power.
