SUZUKI 9.9 HP DF9.9BTHX2 OUTBOARD MOTOR

Description

Here is the Suzuki DF9.9BTHX2 for sale, new in the factory carton and ready to ship worldwide. It is Suzuki’s 9.9 horsepower twin cylinder four stroke on the 25 inch extra long shaft, with electric start, power tilt and a tiller handle. The price is shown on this page.

Extra long shafts are the hardest 9.9 to find in a shop, because few dealers stock them. Most small outboards are sold on 15 or 20 inch legs. If your boat has a tall transom, or if you hang the motor on a bracket well above the water, the longer leg is the whole reason you are looking. We quote delivery before you pay.

This page covers the specs, the model code, why a 25 inch shaft is needed on certain boats, how to measure for it, and what to know about weight, rigging and care. We also point you to the other shaft lengths in case you have measured wrong.

Suzuki DF9.9BTHX2 for sale: Specifications

Market sheets can differ a little, so the engine plate is final. Suzuki’s 2.5 to 30 HP outboard page lists the family if you want to compare.

What the Letters in DF9.9BTHX2 Mean

DF is the four stroke line. 9.9 is the horsepower. B is the engine generation. T is power tilt. H is the tiller handle. X is the 25 inch shaft. The 2 is the production series.

If you want the same motor in white, there is the Suzuki DF9.9BTHXW2. If you need wheel steering on a 25 inch leg, look at the Suzuki DF9.9BTX2. For a 20 inch leg, the Suzuki DF9.9BTHL2 is the match.

Who Needs a 25 Inch Shaft

Sailboat owners are the biggest group. Many yachts carry the auxiliary on a transom bracket high above the waterline, and the stern moves up and down in a seaway. A standard shaft would lift the propeller out of the water with every wave. The extra five inches keeps it submerged.

Catamarans and trimarans with high bridgedeck sterns also need long legs. So do tall sided workboats, big pontoons, and old wooden boats with deep transoms. Some fishermen with high freeboard skiffs use X shafts for the same reason.

If you are replacing an old long shaft motor and it worked well, the Suzuki DF9.9BTHX2 for sale is probably right. If you are not sure, measure.

How to Measure for an X Shaft

Lay a straight edge across the top of the transom. Measure straight down to the bottom of the hull at the centreline. For sailboats with a bracket, measure from the bracket mount to the waterline at normal load, then add the depth the propeller needs. A measurement of about 25 inches calls for this shaft. Around 20 means a long shaft, and around 15 means short.

Be careful on a boat that heels, pitches or carries variable load. A stern bracket that is 25 inches above the keel line in the marina may be 18 inches above the water when a crew of four sits aft. Think about the worst case, not the best.

Boats That Suit the Suzuki DF9.9BTHX2 for sale

Cruising sailboats

Whether a 9.9 is enough depends on the yacht’s displacement and windage, so check with the boat builder or ask us. Tiller steering, power tilt and electric start matter here. Press a switch to lift the motor clear when sailing, so there is no drag.

Small catamarans and trimarans

A single 9.9 on a centre bracket suits a lot of beach cats and cruising cats. Check the bracket rating for engine weight.

High freeboard workboats

River taxis, ferries and fish pen boats with tall transoms benefit. A longer leg gives better prop grip when the boat is loaded.

Old wooden boats

Traditional boats often have deep transoms. A 25 inch shaft fits where a standard leg would hang in the air.

Weight on a Bracket

At about 128 lb the Suzuki DF9.9BTHX2 for sale is the heaviest of the 9.9 range. A stern bracket takes that load a long way behind the transom, which multiplies the strain. Use a proper marine outboard bracket rated for the weight, and fit it to the transom with backing plates through the hull or the stern rail structure.

Check the bracket for movement every season. Bolts loosen, and stainless fittings crack with age. Add a safety cable or chain from the motor to the boat. A dropped motor is expensive.

Power Tilt on a Tall Transom

This is where power tilt shows its worth. Lifting a 128 lb motor from a high bracket by hand is a hard job in a swell. The tilt switch does it for you. Five trim positions let you adjust the angle, and the lock pin holds the leg up while you sail.

Keep the pin and the rams clean. Rinse them after salt. If you leave the boat for a long period, run the tilt through its full travel now and then so the seals do not stick.

Electric Start and the Backup

On a pitching sailboat, pulling a cord with one hand while holding on with the other is no fun. The starter solves that. You still have manual start through the cowling if the battery fails. Use a 12 volt marine battery with clean terminals and an inline fuse, and keep it dry.

The 12 amp alternator will top up the battery as you motor. It is not meant for heavy accessories, so keep the house battery separate.

Motoring a Sailboat With the Suzuki DF9.9BTHX2 for sale

A sailboat auxiliary has a different job from a fishing motor. It has to push a heavy, round hull against wind and tide, keep working for hours at part throttle, and do it from a bracket that sees spray and flying lumps of sea. The Suzuki DF9.9BTHX2 for sale suits that work because the 2.08:1 gearing swings a larger, lower pitch propeller, and the twin cylinder engine is happy at moderate revs.

Do not expect planing speeds on a keel boat. Hull speed is set by the waterline length, and no 9.9 changes that. What a good auxiliary gives you is control in a marina, a way out of a lee shore and a reliable way home when the wind drops.

Before you buy, ask your boat builder or class association what size of motor is recommended. Heavy cruisers sometimes need more than 9.9 HP, and a smaller boat may be overpowered.

Mounting Height on a Bracket

Getting the height right is more work than most owners expect. With the boat loaded and at rest, the anti-ventilation plate should sit below the surface, with the propeller well covered. Then think about what happens when the stern lifts in a wave. If the plate breaks the surface, the prop sucks air and the engine over revs.

Start with the plate a few inches under the water at rest. Run the boat in typical sea conditions and adjust. If the prop ventilates, lower the motor. If it throws spray and drags, raise it a hole. The Suzuki DF9.9BTHX2 for sale has a long enough leg to give you room to adjust either way.

Handle Position and Steering

With a tiller on a high bracket, you often steer from the cockpit by reaching back. A long handle helps. Some owners fit a tiller extension. Others add a remote throttle. Make sure the handle swings clear of the backstay and the rail, and that you can reach the stop button and tilt switch from where you stand.

Set the friction control so the motor holds a heading while you adjust a sheet. When you are done, lock the steering by the tension screw so the motor does not swing when you sail.

Fuel Tank and Line Placement

A fuel line that crosses the cockpit is a trip hazard and a leak waiting to happen. Fit the tank in a vented locker if you can, and run the line through a clamp on the stern rail. Use a fuel filter with a water separator, because condensation in a tank that sits half empty for months is common on boats.

Keep the tank at the same level or slightly above the motor so the fuel flows evenly. Check the line connectors for tight seals every season.

Lifting the Motor Off for Winter

If you take the motor home for the winter, you need two people and a strap. At roughly 128 lb the Suzuki DF9.9BTHX2 for sale is not a one person lift, especially from a bracket on a boat in the water. Use a halyard or a small davit with a lifting strap, and keep the leg vertical so oil stays where it belongs.

Many owners leave the motor on the boat in a mild climate. If you do, tilt it up, spray the exposed metal with protector and cover it.

Why Fuel Injection Matters on a Boat That Sits

A sailboat motor may run for twenty minutes each weekend. A carburettor motor in those conditions often gums up. The Suzuki DF9.9BTHX2 for sale has fuel injection, so it does not have a float bowl or jets to clog. It starts on the first try more often than not, even after a month. We will not promise it never fails, but it is a much safer bet for a boat that sits.

Choosing Between the Suzuki DF9.9BTHX2 for sale and a 20 Inch Model

If the water is flat and your bracket is low, a 20 inch shaft may be enough and the Suzuki DF9.9BTHL2 is a little lighter. If you cruise in swells or the bracket sits high, buy the X. A long shaft that is too short fails every time you meet a wave. A shaft that is too long only costs a bit of drag.

Rigging the Suzuki DF9.9BTHX2 for sale

Fit the motor to the bracket with both clamp screws, evenly tightened, and add a safety cable. Set the height so the anti-ventilation plate sits just below the hull bottom or the waterline, not above it. Connect the fuel line and bulb, then the battery.

Keep the fuel tank where it can be reached and secured. Many sailors use a small tank in a locker with a long line to the motor. Make sure the line is tight against snags and has no kinks.

A standard external fuel tank of about 12 litres usually comes with this class of motor, but ask us what ships with yours.

Propeller Choice for the Suzuki DF9.9BTHX2 for sale

A displacement hull wants a lower pitch propeller than a planing boat. A sailboat auxiliary needs thrust for pushing a heavy hull, not top speed. Tell us the boat type and weight and we will suggest a prop. Suzuki’s genuine parts and accessories page lists props and service items.

Breaking In the Suzuki DF9.9BTHX2 for sale

Follow the break-in procedure in the manual. Keep the throttle varied and moderate for the first hours, avoid long full throttle runs, change the oil early and check the gear oil and clamps after the first trips.

Maintenance

• Flush with fresh water after every salt trip.
• Change engine oil each year or at the manual’s interval.
• Change the gear oil each season. Milky oil means water got in.
• Replace the anode when it is half gone.
• Replace the water pump impeller every couple of seasons.
• Check bracket bolts, clamps and the safety cable.
• Clean the tilt rams and check the battery.

Sailboat motors often sit idle for weeks. Run the Suzuki DF9.9BTHX2 for sale for a few minutes each month, with water supply, to keep everything moving.

Salt Water Care for the Suzuki DF9.9BTHX2 for sale

A motor on a stern bracket takes salt spray every time the boat moves. Flush it after every trip if you can, even if the leg has not been in the sea. Wipe the cowl, rinse the tilt rams and spray the clamp screws and swivel with a light corrosion inhibitor. Check the anode often, because an extra long leg sits in the water longer than a short one. A worn anode leaves the aluminium gearcase to take the damage.

Why Owners Choose the Suzuki DF9.9BTHX2 for sale

Most of the sailors who buy this motor from us have owned a long shaft outboard that was too light or too noisy, or one that would not start when the wind dropped. They want a reliable motor on a tall bracket with a switch to lift it. Fishing boat owners with tall transoms say much the same. They accept the weight in return for a leg that reaches the water in any sea.

Running Costs of the Suzuki DF9.9BTHX2 for sale

Fuel burn depends on the boat, load, prop and sea state, so we do not quote figures. A four stroke runs on plain petrol with its own oil. Parts such as impellers, filters, plugs and anodes are cheap and stocked by Suzuki dealers in most countries. The extra long leg costs a little more than a short one, but it is a one time cost.

Storing the Suzuki DF9.9BTHX2 for sale

Before a long layup, flush the motor, add stabiliser to the tank, change the oil and grease the clamp screws. Store it upright in the position the manual shows, or tilted and locked on the bracket with a cover. Put the battery on a maintainer or take it home. Check the pull start through the cowling once a season so you know it works.

Common Problems and Quick Checks

Starter does not turn. Check the battery, terminals and kill switch lanyard.

Prop ventilates in waves. The motor may be too high on the bracket. Lower it.

Power tilt does not move. Check the fuse and battery voltage.

Cranks but will not start. Check the primer bulb, tank vent and fuel filter.

Weak tell-tale stream. Clear the outlet and check the impeller.
