YAMAHA 9.9 HP F9.9SMHB OUTBOARD MOTOR

Description

We have the Yamaha F9.9SMHB for sale, new in its crate and ready to ship anywhere in the world. It is Yamaha’s 9.9 horsepower four-stroke with a 15 inch shaft, a 212 cc twin cylinder engine, tiller steering, a pull start and a proper forward, neutral and reverse gearbox. It weighs about 87 pounds and runs from a separate portable fuel tank.

The 9.9 is one of the most popular outboard sizes in the world, and there are good reasons for that. It is the most power you can get from a portable twin that one or two people can still lift. In many places it also sits just under horsepower limits that apply on lakes, rivers or for licensing, so it gives you as much performance as possible without crossing those lines. On the right boat it planes easily, it trolls smoothly, it sips fuel and it is simple to look after. If your inflatable, RIB, jon boat or small aluminium boat has a 15 inch transom and is rated for it, the Yamaha F9.9SMHB for sale is hard to beat. This page covers the full specs, how to read the model code, which boats suit it, how it runs, how to set it up and look after it, and how ordering from us works.

Yamaha F9.9SMHB Specifications

These are Yamaha’s published figures for the F9.9, which you can check on Yamaha’s 9.9 and 8 HP portables page. The Yamaha F9.9SMHB for sale here is the short shaft, manual start, tiller model, the simplest and lightest version of the 9.9.

Reading the Model Code

F stands for four-stroke. 9.9 is the horsepower. S means the short 15 inch shaft. M means manual start. H means tiller handle. B is the design generation. So the Yamaha F9.9SMHB for sale is the 15 inch, pull start, tiller version. There is also a 20 inch long shaft pull start model, the Yamaha F9.9LMHB, and an electric start remote model, the Yamaha F9.9LEB. If you want extra thrust for a heavy boat, the T9.9 high thrust models are a different design worth a look too.

Why the 9.9 Is So Popular

Walk around almost any marina, lake or boat ramp and you will see 9.9 HP outboards like the Yamaha F9.9SMHB for sale everywhere. There are three main reasons.

The first is the power to weight ratio. The Yamaha F9.9SMHB for sale weighs about the same as the 8 HP, around 87 pounds, but makes nearly 25 percent more power. That is the most horsepower you can get in a motor that is still realistically portable. Two people can lift it on and off a boat without special equipment.

The second is that 9.9 sits just under 10 HP. In a number of countries, regions and individual lakes, there are rules that change at 10 HP. Some waterways only allow motors under 10 HP. Some places require a licence or registration above that level. The 9.9 gives you as much performance as possible while staying on the right side of those limits. Check your own local rules, because they vary a lot.

The third is versatility. A 9.9 can be the main motor on a small boat, a tender motor for a yacht with a bigger dinghy, or a kicker on a larger fishing boat. It does all three well, which is why so many people end up owning one.

Boats That Suit the Yamaha F9.9SMHB for Sale

Inflatables and RIBs

Most inflatables and RIBs from about 10 to 13 feet are rated somewhere around 10 to 20 HP. On these boats, the 9.9 is a great match. It will usually get two adults onto the plane, which makes tender runs and exploring trips far quicker than with a smaller single cylinder motor.

Jon boats and small aluminium fishing boats

On a 12 to 14 foot jon boat or a small aluminium skiff with a 15 inch transom, the Yamaha F9.9SMHB for sale is a classic fishing setup. It gets you to the fishing grounds at a decent speed, and its smooth twin cylinder idle is comfortable for trolling.

Small fibreglass skiffs and dinghies

Light fibreglass skiffs and sailing dinghies with 15 inch transoms rated for 9.9 HP also suit it well.

Kicker on a larger boat

Some owners use a 9.9 as a trolling kicker on a bigger boat. For that job, a long shaft or a high thrust model is usually better, because larger boats tend to have taller transoms and need more thrust at low speed. But on smaller boats with a 15 inch kicker bracket, the short shaft can work.

How the F9.9 Runs

Starting

The Yamaha F9.9SMHB for sale is pull start only. That might sound like a drawback, but a twin cylinder 212 cc engine is easy to pull over, and Yamaha’s starting system is smooth. From cold, pull the choke, put the motor in neutral and give a firm, steady pull. It usually fires on the first or second try. When warm, it nearly always starts on the first pull. No battery means nothing to go flat over the winter and nothing extra to carry or charge.

Acceleration

Yamaha fits an acceleration pump to the carburettor on the Yamaha F9.9SMHB for sale. When you open the throttle quickly, it squirts a little extra fuel into the engine so the motor picks up cleanly without stumbling. In practice, that means a crisp response when you open the throttle to get the boat onto the plane.

Shifting and reverse

The gear lever on the Yamaha F9.9SMHB for sale is on the side of the motor. Bring the throttle back to idle, then shift. Reverse is strong and makes docking, backing away from a beach and holding position against a current easy.

Steering

Yamaha gave the Yamaha F9.9SMHB for sale a shorter tiller handle, which is more comfortable to use, especially in a small boat where space is tight. There is a steering friction adjustment so you can set how freely the motor turns. Tighten it a bit if you want the motor to hold a straight course while you take your hand off.

Smoothness and noise

As a twin cylinder four-stroke, the Yamaha F9.9SMHB for sale is smooth and quiet. There is very little vibration through the tiller and no smoke or two-stroke smell. You can talk to your passengers at cruising speed without raising your voice.

Shallow Water Drive

The shallow water drive on the Yamaha F9.9SMHB for sale lets you lock the motor at a partly tilted angle and run slowly with the lower unit higher in the water. It is a handy feature on rivers, sandbars, flats and shallow beaches. Use it at low speed only, and watch the cooling water stream, because in very shallow water the intake can pick up sand or mud.

Fuel Supply

The Yamaha F9.9SMHB for sale runs from a separate portable tank, connected by a hose with a primer bulb. That gives you a lot more range than a small built-in tank and keeps the weight of the fuel low on the floor of the boat. Before starting, open the tank vent and squeeze the primer bulb until it feels firm. When you finish, close the vent and disconnect the hose before you lift the motor or the tank.

Use fresh unleaded with no more than 10 percent ethanol. If the boat will sit for more than a few weeks, add a fuel stabiliser or run the carburettor dry. Stale fuel is the biggest single cause of poor running and hard starting on small carburetted motors.

Speed and Performance

On a 10 to 12 foot inflatable or RIB with two adults, the Yamaha F9.9SMHB for sale will usually get the boat onto the plane and hold it there comfortably. On a light jon boat with one angler, it gives a brisk run to the fishing spot. As always, real speeds depend on the hull, the load, how weight is placed and the conditions. Treat any figure you read online as a rough guide. What we can say is that the jump from a 6 HP single to a 9.9 twin on a planing dinghy is usually dramatic: from slow displacement speed to properly skimming along.

Fitting the Motor

Before fitting the Yamaha F9.9SMHB for sale, check your boat’s capacity plate and make sure 9.9 HP and about 87 pounds are within the limits. At this weight, two people make lifting the motor onto the transom easier and safer. Clamp it in the centre of the transom, tighten both clamp screws firmly and fit a safety line from the motor to the boat.

Check the height. The anti-cavitation plate just above the propeller should sit level with or slightly below the bottom of the hull. Then set the trim rod so the motor’s leg is vertical when the boat is running with its normal load. If the bow rides very high, move the rod in a hole. If the bow ploughs into the water, move it out.

Connect the fuel tank, check the engine oil, put the motor in neutral, start it and look for the cooling water stream from the tell-tale. Then you are ready to go.

Breaking In a New Motor

Every new Yamaha needs a gentle break-in, and the Yamaha F9.9SMHB for sale is no exception. For the first hours, run at varied low and medium throttle settings, add short bursts of higher throttle as the hours go on, and avoid long periods at full throttle. Check the oil before each trip. When the break-in is finished, change the engine oil. The exact procedure is in the owner’s manual, which Yamaha also offers as a free download on its owner’s manual page.

Maintenance

After every trip in salt or brackish water, flush the cooling system with fresh water. Use a flushing attachment or stand the motor in a tub of fresh water deep enough to cover the intake and run it at idle for a few minutes. Rinse the outside too, especially the clamps, the swivel bracket and the lower unit. While the motor runs, glance at the cooling tell-tale. A strong, steady stream means the water pump is working properly.

Once a season, or at the hours listed in the manual, change the engine oil (about 0.8 litre) and the gear oil, check the spark plugs, grease the clamp screws, swivel and tilt points, check the propeller for damage, check the anode and inspect the fuel filter and hose. Every few seasons, replace the water pump impeller. In sandy or silty water, do it more often.

Before winter storage, run the carburettor dry or treat the fuel with stabiliser, change the oil, flush with fresh water, change the gear oil and store the motor upright somewhere dry. In cold places, make sure all water has drained before frost. Look after the Yamaha F9.9SMHB for sale like this and it will start reliably for many seasons.

Troubleshooting

Most starting and running problems on the Yamaha F9.9SMHB for sale have simple causes. If the motor will not start, check that the tank vent is open, the hose is clipped on firmly at both ends, the primer bulb is firm and the fuel is fresh. Make sure the kill cord clip is in place. If you have used a lot of choke on a warm engine, it may be flooded: push the choke in, open the throttle a little and pull a few times. If the motor starts and then dies after a minute, the tank vent is usually closed.

If the cooling stream is weak, clear the tell-tale outlet with a thin wire. If it stays weak, the intake may be blocked or the impeller worn. If the motor revs but the boat does not move well, check the propeller for damage or a fishing line wrapped around the shaft.

Running Costs

The Yamaha F9.9SMHB for sale is economical to run. Four-stroke twins burn modest amounts of fuel at a sensible cruise. Oil changes need under a litre. Plugs, impellers, anodes and gear oil are all inexpensive and widely available. There is no battery and no electronic control system. Many owners spend very little per year keeping their 9.9 in good shape.

Using It in Salt Water

Yamaha builds its portables with corrosion resistant alloys, protective paint and a sacrificial anode. Salt water still needs care: flush after every use, keep the anode in good condition, rinse the outside and spray the powerhead with a corrosion protection product now and then. With those habits, the Yamaha F9.9SMHB for sale will handle coastal use for years.

The 9.9 as a Yacht Tender Motor

Cruisers with a larger tender often choose the Yamaha F9.9SMHB for sale because it lets the dinghy plane with two or three people aboard. That turns a slow, wet ride ashore into a quick run, and it means you can anchor further out in a bay and still get to the beach easily. The trade-off is weight. At around 87 pounds, the motor is a two-person lift between the yacht and the tender, or a job for a small davit or lifting tackle from the boom. Always clip a line onto the motor before you move it.

At anchor overnight, tilt the motor up so weed and barnacles do not grow on the lower unit, and lock it to the transom with a cable lock in busy harbours. When you land on a beach, tilt up early and walk the last few metres so sand does not get into the water pump.

The 9.9 on a Fishing Boat

On a small aluminium or jon boat, the Yamaha F9.9SMHB for sale is a very capable fishing motor. It runs you out to the grounds at a good clip, then idles down smoothly for trolling. Because it is a twin, the idle is far smoother than a single cylinder, which makes long trolling sessions more comfortable. With a 12 or 24 litre tank on the floor, you can fish all day without thinking about fuel.

Accessories Worth Having

A bigger portable fuel tank is the first thing most owners add if one did not come with the motor. A cover protects the cowling. A flushing attachment makes salt water care easy. A spare propeller is cheap insurance if you run in rocky or shallow water. A cable lock deters theft. None of these are required to use the Yamaha F9.9SMHB for sale, but they make life easier over a long season.

What Comes in the Crate

The motor arrives assembled with the propeller fitted, the owner’s manual and the factory paperwork. Whether a portable fuel tank is included depends on the shipment, so ask us when you order if you need one. Check the oil tag and the oil level before the first start, because motors sometimes ship with little or no oil in the crankcase.
