HONDA 9.9 HP BF10D3SH Outboard Motor

Description

Dinghies, inflatables and small tenders live and die by weight. Hang a heavy motor off a light boat and it squats, sprays and handles badly. The Honda BF10D3SH for sale on this page is Honda’s 9.9 HP four stroke with a short 15 inch shaft, one of the lightest four strokes in its class. It is brand new in the crate and we ship it worldwide.

Below you will find what the model code means, the full specifications, how the motor runs, which boats it suits, how to set it up and look after it, and how ordering works. The price and cart are at the top of the page.

The Honda BF10D3SH for sale in Short

The Honda BF10D3SH for sale is a 9.9 HP, 222 cc, twin cylinder four stroke with a single overhead cam, four valves and one carburettor. It has pull start, tiller steering and manual tilt, and a 15 inch shaft. Honda lists the S type BF8 and BF9.9 at about 92 pounds dry.

What the Model Code Means

• BF: Honda four stroke outboard.
• 10: the 9.9 HP model (Honda uses 10 in the code).
• S: short shaft, 15 inches (381 mm).
• H: handle, meaning tiller steering.

Related models: the electric start short shaft Honda BF10DK3SHS, the 20 inch Honda BF10DK3LH, and the 8 HP Honda BF8DK3SHA.

Specifications of the Honda BF10D3SH for sale

All figures come from Honda’s official BF8 and BF9.9 specification page.

How the Honda BF10D3SH for sale Runs

Honda’s 222 cc twin is a smooth, quiet little engine. Two cylinders fire more evenly than a single, so there is far less vibration through the tiller handle. It idles steadily, which makes slow trolling easy, and it responds cleanly when you open the throttle. Fuel use is tiny, and there is no smoke or oily smell like an old two stroke.

The BF9.9 is tuned to make its power at 5,500 RPM. It revs a little higher than the BF8 and gives you that bit of extra push that helps a 12 to 14 foot boat plane with two people aboard.

The gear ratio is 2.33:1, which is on the low side for a motor this size. That helps it swing a four blade prop with good grip, useful for heavier small boats and for trolling.

Why the 15 Inch Shaft Matters

On a 15 inch transom, a short shaft puts the anti ventilation plate about level with the bottom of the hull and the prop in clean water just below. A longer shaft would hang too deep, add drag and spray and make it easier to hit rocks. Most inflatables, dinghies and small car top boats have 15 inch transoms, which is why the short shaft Honda BF10D3SH for sale suits them so well.

Pull Start Made Easy

Honda fits these small twins with a decompression system and digital CDI ignition so they pull over easily, often with one hand. With the choke used properly on a cold engine, a well maintained Honda BF10D3SH for sale usually starts in a pull or two. There is no battery to go flat, which suits boats that sit for weeks at a time, tenders and boats kept at remote cabins.

Tilting and Shallow Water Drive

At under 110 pounds, the motor is easy to tilt by hand. Release the tilt lock, lift using the handle and engage the tilt support. For shallow water, the shallow water drive position lets you run slowly with the motor partly raised. Keep the water intake submerged and watch the cooling water tell tale.

Setting the Trim

The running angle is set with a five position adjuster on the bracket, from 4 to 20 degrees. Choose the position that keeps the motor roughly vertical when the boat is running with your usual load. If the bow ploughs, move out one position. If it bounces, move in one. On displacement boats, a vertical motor usually gives the best push.

Boats That Suit the Honda BF10D3SH for sale

• Inflatables and small RIBs with a 15 inch transom rated for 9.9 HP.
• Yacht tenders that need to plane with two aboard.
• Aluminium dinghies and small car top boats.
• Small skiffs used in shallow creeks.
• Boats in places where 9.9 HP is the licensing limit.

Always check the capacity plate for maximum horsepower and engine weight, especially on inflatables.

Mounting the Motor

Mount it on the centreline of the transom and tighten the clamp screws firmly. Check them again after the first trip, because tiller motors can creep with vibration. Start with the anti ventilation plate about level with the bottom of the hull. On an inflatable, use a transom pad under the clamps and make sure the transom board is sound.

Choosing a Propeller

At full throttle with your usual load, the engine should reach 5,000 to 6,000 RPM. If it falls short, a lower pitch helps; if it overshoots easily, go up. Very heavy boats may be better served by a Power Thrust model. Honda’s propeller selector is a handy reference.

A Day Out

You clamp the Honda BF10D3SH for sale onto your inflatable, give one pull and it settles into a quiet idle. With a friend aboard, you open the throttle and the boat climbs onto plane, something an 8 might struggle with at that load. You spend the afternoon exploring the coast, pull up on a beach for a swim and tilt the motor up by hand. On the way home, the twin hums along, barely touching the fuel.

8 or 9.9 HP?

The BF8 and BF9.9 share the same 222 cc engine and weigh the same. The 9.9 is tuned to make more power at a higher RPM. If your boat is rated for 9.9 HP, the extra power costs nothing in weight and helps with heavier loads. If it is rated for 8, stay with the 8. In some places, licensing or waterway rules also depend on horsepower, so check what applies where you boat. Either way, the Honda BF10D3SH for sale is built on the same smooth, reliable engine.

Carrying and Storing a Portable

At around 92 pounds, this is a one or two person carry. Always carry and store the motor the way the owner’s manual shows, usually upright or on a specified side, so oil stays in the sump. Use a proper outboard stand or rail bracket and keep it covered.

Who Buys the Honda BF10D3SH for sale

Inflatable and tender owners who want their boat to plane with two people, dinghy owners, cabin owners and anglers in places where 9.9 HP is a common licensing or waterway limit. The Honda BF10D3SH for sale gives them the most power in Honda’s light portable range without adding any weight over the 8.

Is the Honda BF10D3SH for sale Right for You?

If your boat has a 15 inch transom and a 9.9 HP rating, and you want a light, simple motor with no battery, the answer is yes. If you restart often or would rather use a key, the BF10DK3SHS adds electric start. For most small inflatables and tenders, the Honda BF10D3SH for sale is the sweet spot of power and weight.

Break-In and the First Service

New engines need a gentle start. Run the motor at a mix of speeds for the first few hours, keep long full throttle runs to a minimum and follow the break-in section of the owner’s manual. Then do the first oil and filter change and check the gearcase oil. It takes little time and money, and it sets the Honda BF10D3SH for sale up for a long life.

Fuel Quality Wherever You Boat

Clean fuel keeps any outboard happy. In hot, humid places, or wherever fuel is stored in drums, water finds its way into tanks. Run the Honda BF10D3SH for sale through a water separating filter, look at the bowl before each trip, and replace the element on schedule. Fill up at busy stations and don’t leave fuel sitting in a tank for months without a stabiliser.

Carburettors are simple and can be serviced almost anywhere, but stale fuel leaves sticky deposits in their tiny jets. Drain the carburettor before long storage, as the owner’s manual describes, and most starting trouble never happens.

Salt Water Care

Salt is hard on every engine. After each trip in salt or brackish water, flush the Honda BF10D3SH for sale with fresh water, rinse the outside, and keep an eye on the anodes. Replace them once they are roughly half gone. Paint chips on the gearcase should be touched up quickly, and a corrosion inhibitor spray on the powerhead now and then helps a lot.

Storage Between Seasons

For a long layup, change the oil, deal with the fuel as the manual describes, flush the engine and check the gearcase oil for any sign of water. Store the motor trimmed or stood so the lower unit drains. In warm, damp places, cover the boat and start the engine every couple of weeks.

New Versus Used

A second hand motor comes with questions nobody can answer for certain: missed services, salt damage, an overheat years ago. Buying the Honda BF10D3SH for sale new means zero hours, a known history and factory cover where it applies.

Why Honda

Decades of building car, motorcycle and generator engines sit behind every Honda outboard. The company committed to four strokes long before most rivals, and that head start shows in how quiet, economical and dependable its motors are.

Service and Parts Near You

Honda has marine dealers and distributors in many countries, and routine parts such as filters, plugs, anodes and impellers are widely stocked. Look up your nearest service point on Honda’s dealer locator or through your local distributor before you order.

Safety

Wear the kill switch lanyard whenever the engine is running. Carry life jackets for everyone, a way to call for help and basic tools and spares. Check fuel and oil before every trip and tell someone your plans. Honda’s boating safety tips are worth a read at the start of each season.

Keep a Service Log

A simple notebook or phone note with hours, services and parts is worth its weight in gold. It reminds you what is due, helps your mechanic, and makes the Honda BF10D3SH for sale easier to sell for a good price one day.

Common Mistakes to Avoid

Ordering the wrong shaft length. Ignoring the capacity plate. Forgetting controls, harness or a battery where needed. Mounting a new motor on a damaged transom. Never checking wide open throttle RPM after fitting a prop. Skipping the first service. Letting fuel go stale. Each is easy to avoid, and avoiding them keeps the Honda BF10D3SH for sale running well for years.

Getting Ready Before the Motor Arrives

While the crate is on its way, get the boat ready. That way the Honda BF10D3SH for sale can go on the transom the day it arrives.

• Measure the transom height and confirm the shaft length.
• Check the capacity plate for maximum horsepower and engine weight.
• Inspect the transom for soft spots, cracks or corrosion and repair them.
• Replace old fuel hoses and fit a water separating fuel filter.
• Pick a first propeller to try.

Weight and Balance

On a tiller boat the stern carries the motor and the driver, which can make the bow ride high. Spread the load forward, keep the fuel tank central and your boat will run far better with the Honda BF10D3SH for sale on the back.

Real World Performance

Top speed and fuel use depend on hull, load, prop, motor height and trim, so any single number is only a guide. Honda publishes real test results, with speed, RPM, fuel flow and the prop used, on its performance test page. Look for a boat similar to yours for a realistic idea of what to expect from the Honda BF10D3SH for sale.

Trailering

For trailering, tilt the motor up and support it with the tilt lock or a transom saver bar so the lower unit clears the road and the bracket isn’t taking every bump. Remove the key where fitted and disconnect a portable fuel tank. At the ramp, only lower the motor once the water is deep enough to cover the cooling water intake.

Spares Worth Keeping Aboard

A spare spark plug, a fuel filter element, a spare prop nut and cotter pin, and the basic tools to fit them take up almost no space. Far from help, those few items can save your day.

Living With It Long Term

Look after the basics, oil, filters, impeller, anodes and clean fuel, and the Honda BF10D3SH for sale should give many years of dependable running. Honda four strokes are known for going a long way on simple, regular care.

Commercial and Rental Use

Marinas, lodges, fish farms and rental fleets run Honda outboards because they start easily and keep going. If you plan to use the motor commercially, check the warranty terms in your country, since commercial cover is usually shorter than recreational cover, and keep closely to the service schedule.

Resale Value

Honda outboards are always in demand on the used market because people know how long they last. Keep your receipts and a simple service record, and the Honda BF10D3SH for sale will hold its value well and help your boat sell when the time comes.

Choosing the Right Horsepower

The capacity plate on your boat sets the upper limit, and it should never be exceeded. Below that, match the motor to your use: more people, more gear and rougher water call for more power, while light, calm water boating is happy with less. If you are between two sizes, tell us about your boat and we will give you an honest opinion on whether the Honda BF10D3SH for sale is the right one.

Register Your Motor

Wherever you live, register your new outboard with the local Honda distributor if registration is offered in your country. It makes warranty claims simpler and means you hear about any service updates. Keep your purchase papers with your service log.
