HONDA 9.9 HP BF10DK3SHS 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 BF10DK3SHS 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 BF10DK3SHS for sale in Short

The Honda BF10DK3SHS 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 electric start with a 12 amp alternator, tiller steering and manual tilt, and a 15 inch shaft. Honda lists the S type BF8 and BF9.9 at about 92 pounds dry, with a little more for the starter and other added equipment.

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.
• S (after the H): electric starter.

Specifications of the Honda BF10DK3SHS for sale

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

How the Honda BF10DK3SHS 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 BF10DK3SHS for sale suits them so well.

Electric Start

Turn a key and go. No standing in a rocking boat pulling a cord, no sore shoulder after a day of moving between spots. Electric start models also get a 12 amp alternator, and Honda notes it reaches full output at only 3,000 RPM, so it keeps a battery charged even at modest cruising speeds. The trade off is a battery to carry and maintain.

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 BF10DK3SHS for sale

• Inflatables and small RIBs with a 15 inch transom rated for 9.9 HP.
• Yacht tenders used by guests and crew.
• Dive and snorkel inflatables that stop and start often.
• Aluminium dinghies and small skiffs.
• Boats on waters with a 9.9 HP 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 Battery

Use a marine starting battery of the size the owner’s manual recommends, in a secured box, as far forward as the cables allow for balance. Keep terminals clean and tight. The 12 amp alternator keeps it charged while you run.

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

Your guests take the tender to a snorkelling spot. They turn the key, the Honda BF10DK3SHS for sale starts, and the inflatable planes off with two aboard. At the reef they shut down, snorkel for an hour, climb back in and start it again with the key. Nobody has to stand up in a rocking dinghy and pull a cord. The battery stays topped up by the 12 amp alternator.

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 BF10DK3SHS 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. Disconnect the battery first. Use a proper outboard stand or rail bracket and keep it covered.

Who Buys the Honda BF10DK3SHS for sale

Yacht owners with tenders, dive operators, inflatable owners who want key start, and anglers in places with a 9.9 HP limit. They choose the Honda BF10DK3SHS for sale for its light weight, short shaft and the convenience of electric start.

Is the Honda BF10DK3SHS for sale Right for You?

If your boat has a 15 inch transom and a 9.9 HP rating, and you want key start, the answer is yes. If you would rather avoid a battery, the pull start BF10D3SH is lighter and simpler. For tenders used by guests, the Honda BF10DK3SHS for sale is hard to beat.

Break-In and the First Service

For the first several hours, vary your throttle, avoid long stretches at full throttle and don’t hold one steady RPM for ages. The owner’s manual gives the exact steps. After break-in, change the engine oil and filter and check the gearcase oil. That first service clears out the fine particles from new parts bedding in, and it is one of the cheapest ways to help the Honda BF10DK3SHS for sale last.

Fuel Quality Wherever You Boat

Water, dirt and stale fuel cause more outboard problems than anything else. Fuel quality varies from country to country and from one station to the next, and boats that sit in heat collect condensation in their tanks. Fit a good water separating filter, check the bowl often and change the element when due. Buy from busy stations, keep containers clean and sealed, and add stabiliser if the boat will sit for more than a few weeks.

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

Honda protects its outboards with layered paint, sacrificial anodes and sealed electrical connectors, but salt always wins against neglect. Flush the engine with fresh water after every salt trip, rinse the outside, check the anodes each season and replace them when about half worn, and touch up any chipped paint on the lower unit before corrosion spreads.

Storage Between Seasons

Before storing the motor for more than a month or two, change the oil so old oil doesn’t sit inside, treat or drain the fuel, flush the cooling system, check the gearcase oil for water and store the motor so water drains from the lower unit. In hot, humid climates, keep the boat covered and run the engine every few weeks if you can.

New Versus Used

Used outboards can look like a bargain, but you rarely know the full story. Was it flushed after salt? Were oil changes done on time? Did it ever overheat? A brand new Honda BF10DK3SHS for sale starts at zero hours, with a clean history and factory warranty coverage where it applies. For a motor you plan to keep, that certainty is worth paying for.

Why Honda

Honda is an engine company first. Its outboards borrow heavily from its car, motorcycle and power equipment engines, which is why they tend to start easily, run smoothly and keep going for years with ordinary care. Honda was also one of the first big outboard makers to go fully four stroke, long before emission rules pushed the rest of the industry that way.

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

From day one, write down engine hours, services and parts. It keeps you on schedule, helps any mechanic diagnose problems and adds real value when you sell. Honda motors hold their value well on the used market, and a documented history makes that even more true.

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 BF10DK3SHS 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 BF10DK3SHS 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.
• Charge or buy a good marine battery, box and cables.
• 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 BF10DK3SHS 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 BF10DK3SHS 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. Read the owner’s manual section on emergency starting before your first trip, so you know what to do if the battery ever fails. 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 BF10DK3SHS 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 BF10DK3SHS 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 BF10DK3SHS 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.
