Suzuki 9.9 HP DF9.9BTX5 Outboard Motor

Description

The Suzuki DF9.9BTX5 for sale here is a new 9.9 HP remote control outboard with a 25 inch extra long shaft, electric start and power tilt. It ships worldwide in the factory crate, the price is on this page, and we quote delivery to your door before you pay.

This is the motor for a tall transom and a helm. Sailing catamarans, high sided tenders, small workboats with a console and pontoon style boats with a deep stern all need the prop well down in the water. The Suzuki DF9.9BTX5 for sale puts it there, and you drive it from a remote control box instead of hanging over the back.

On this page you will find what the code means, the full spec table, how to rig a remote 9.9, how to check that 25 inches is really what your boat needs, break-in, service, salt water care and our answers to common questions. If you are still unsure after reading, contact us with a photo of your stern.

Reading the model code on the Suzuki DF9.9BTX5 for sale

Suzuki packs the whole spec into the code. If you read it right you know exactly what will arrive. Here is the Suzuki DF9.9BTX5 for sale letter by letter.

• DF: Suzuki four stroke outboard.
• 9.9: 9.9 horsepower, the class that many lakes, marinas and licence rules treat as the upper limit for a small motor.
• B: the fuel injected generation of the Suzuki 9.9, with Lean Burn control.
• T: power tilt, which on this range also brings electric start.
• No H: there is no tiller. Steering, throttle and shift are by remote control.
• X: extra long shaft, 25 inches.
• 5: production version suffix.

No W, so the cowl is the standard dark Suzuki colour. If you want white, ask about the Suzuki DF9.9BTXW5. If you would rather steer by hand, the tiller version is the Suzuki DF9.9BTHX5.

Who buys the Suzuki DF9.9BTX5 for sale

Not many boats need a 25 inch shaft and remote controls at 9.9 HP, but the ones that do have few other options. The Suzuki DF9.9BTX5 for sale is mostly bought for:

• Sailing catamarans of about 30 to 40 feet that use an outboard in a well or on a bracket between the hulls, run from the cockpit.
• Sailboats with a high stern where a long shaft prop lifts out of the water in a following sea.
• Houseboats and small barges with a deep stern and a helm forward.
• Workboats and dive tenders with a console and a high transom.
• Auxiliary motors on bigger boats where the kicker is run from a remote at the helm.

On a catamaran or sailboat, the extra long shaft is the difference between a motor that pushes in a swell and one that screams as the prop comes out. We have customers who first bought a 20 inch motor, then came back for the Suzuki DF9.9BTX5 for sale after one rough harbour entry.

Remote control also makes sense for anyone who runs the boat standing or seated forward. A 25 inch tiller is awkward to reach on a tall stern, so most buyers on those boats go remote.

Suzuki DF9.9BTX5 for sale: specifications

The 9.9 uses the same 327 cc block as the Suzuki 15 and 20, tuned for 9.9 HP. That gives it plenty of low speed torque for its class, which helps on a heavy catamaran. The official Suzuki 2.5 to 30 HP range page lists the full family if you want to compare.

Features worth knowing on the Suzuki DF9.9BTX5 for sale

Fuel injection

No carburettor. The Suzuki DF9.9BTX5 for sale starts cleanly cold and does not need a choke. Fuel injection also handles the occasional long lay-up much better than a carb, which matters on a cruising boat where the motor may sit for weeks.

Lean Burn

At steady cruise the ECU leans the mixture. On a sailboat motoring in a calm for hours, that adds up. Owners tell us they get more hours out of a tank than with the older carb 9.9s.

Power tilt

A 25 inch shaft motor sticks well down. When you anchor or moor, you want it up and out of the water to stop growth on the lower unit. The Suzuki DF9.9BTX5 for sale does that from a switch, which beats leaning over a high stern to lift 125 lb by hand.

Charging

The alternator puts charge back into the battery while you motor. On a sailboat it helps top up the house bank, but it is a small alternator. Do not rely on it alone for a boat with a fridge and an autopilot.

High thrust on a 9.9

Suzuki offers props for the 9.9 in several pitches. For a heavy catamaran, a lower pitch prop helps the Suzuki DF9.9BTX5 for sale reach its rpm range under load. Ask us which prop suits your boat before we ship.

Rigging: what you need besides the motor

A remote motor needs more parts than a tiller. Plan these before the Suzuki DF9.9BTX5 for sale arrives, so you are not waiting on a cable in the middle of the season.

• Remote control box: a Suzuki side mount or top mount control with throttle and shift in one lever. It usually holds the key switch and kill cord.
• Main wiring harness: connects the control box and key switch to the motor. Length depends on your boat.
• Throttle and shift cables: two cables, measured along the real cable path plus a little slack.
• Steering: a mechanical cable steering system, or a link arm if the motor is steered with the boat’s rudder on some catamarans. Some installs fix the motor straight and steer with the rudder.
• Battery: a marine starting battery with fuse and cables.
• Fuel tank and line: portable tank or a built-in tank with a filter.
• Propeller: one is supplied, but a different pitch may suit you better.

We can supply the Suzuki control box, harness and cables with your motor so everything matches. Genuine parts and accessories are also listed on the Suzuki genuine parts site.

Measuring control cables

Run a piece of rope along the path the cable will take, from the control box to the motor, following the gentlest bends. Measure the rope and round up to the next foot. Too short and the motor cannot steer or tilt fully. Too long and you have loops that stiffen the action.

Is 25 inches right for your boat?

This is the most important check before you order the Suzuki DF9.9BTX5 for sale. Measure from the top of the transom or bracket clamp point down to the bottom of the hull, or on a sailboat, to the waterline with the boat loaded.

• About 15 inches: short shaft, see the Suzuki DF9.9BTS5.
• About 20 inches: long shaft, see the Suzuki DF9.9BTL5.
• About 25 inches: extra long, the Suzuki DF9.9BTX5 for sale on this page.

On a planing boat the anti-ventilation plate should sit level with the bottom of the hull. On a displacement boat like a cat or sailboat, you want the plate well below the surface, often 4 to 6 inches, so the prop stays in the water when the stern lifts in waves. That is why so many sailing buyers need extra long.

If your motor sits in a well, measure from the clamp point to the bottom of the well opening. Send us the numbers and we will confirm.

Break-in for the Suzuki DF9.9BTX5 for sale

Follow the procedure in your owner’s manual. The usual pattern for this range looks like this.

• First 2 hours: under half throttle, varying speed. A short burst higher now and then is fine.
• Third hour: up to about three quarter throttle.
• Up to 10 hours: short periods at full throttle are fine, avoid long runs flat out.
• At 20 hours: first service with oil, gear oil and checks.

On a sailboat, people tend to run the Suzuki DF9.9BTX5 for sale at one steady speed for hours. During break-in, change speed every 10 to 15 minutes. It matters for the rings.

Maintenance schedule

For the Suzuki DF9.9BTX5 for sale on a cruising boat, carry a spare impeller, plugs, a fuel filter and a spare prop shear parts kit if your prop uses one. They are small and cheap, and they fix most problems far from a dealer.

Salt water care

Most buyers of the Suzuki DF9.9BTX5 for sale use it in salt. Flush it with fresh water after use through the flush port, rinse the outside and spray the bracket and tilt unit with a corrosion inhibitor.

When the boat sits on a mooring, tilt the motor fully up. Growth on the lower unit will block the water intake and damage the impeller. If you cannot flush after every trip, at least flush it every time you are back at a dock with fresh water.

Check the anodes every few months in warm water. Never paint them. Replace when about half gone.

Problems we hear about, and the fixes

Motor cranks but will not start

Check the lanyard is clipped into the control box, the lever is in neutral, the fuel vent on the tank is open and the bulb is firm. That covers most cases with the Suzuki DF9.9BTX5 for sale.

Stiff shift or throttle

Usually a cable routed with too tight a bend or dried out. Re-route, grease the ends, or replace the cable.

Prop comes out of the water

Check mounting height. On a sailboat bracket, lower the bracket or confirm you have the 25 inch shaft.

Overheat alarm

Stop and check the tell-tale stream. Weed or a plastic bag over the intake is common. If clear, the impeller may be worn.

Suzuki DF9.9BTX5 for sale compared with its neighbours

• Suzuki DF9.9BTX2: same spec, earlier production version. Check stock and price.
• Suzuki DF9.9BTHX5: tiller version with the same 25 inch shaft and power tilt.
• Suzuki DF9.9BTL5: remote with 20 inch shaft.
• Suzuki DF15AEL5: 15 HP long shaft for boats that allow more power.
• Suzuki DF20ATL5: remote 20 HP with power tilt, for heavier boats.

The Suzuki DF9.9BTX5 for sale gives the same engine as the 15 and 20 but at 9.9 HP. That is often a licence or marina rule choice. If you have no such limit and a heavy boat, the remote 20 is worth a look. See all 9.9 versions in our Suzuki 9.9 HP category and the whole range in Suzuki outboards.

Running twin Suzuki DF9.9BTX5 for sale motors on a catamaran

A lot of our catamaran customers order two motors, one for each hull. Twin installs give you real control in a marina. You can turn the boat almost on the spot by running one motor ahead and one astern. With a pair of the Suzuki DF9.9BTX5 for sale, each motor gets its own control lever, or you use a twin binnacle control.

Twin installs need two harnesses, two sets of cables and usually two batteries or a split charging setup. Plan where the cables will run through the bridge deck before ordering. Some owners link the two motors with a tie bar and steer both with the rudders. Others fix the motors straight ahead and leave the steering to the rudders at speed.

On the fuel side, each motor should have its own fuel line and filter. If one line takes air or water, you still have the other motor. That redundancy is the main reason cruising sailors pick two Suzuki DF9.9BTX5 for sale motors over one larger engine.

Choosing a prop for the Suzuki DF9.9BTX5 for sale

The prop supplied with the motor suits an average boat. Many buyers of the Suzuki DF9.9BTX5 for sale have heavy displacement boats, so a lower pitch prop is often better. The goal is simple: at full throttle with a normal load, the engine should reach the 5,000 to 6,000 rpm range.

• If the motor will not reach 5,000 rpm at full throttle, the pitch is too high. Go down a size.
• If it goes past 6,000 rpm easily, the pitch is too low. Go up a size.
• For pushing a heavy boat into wind and waves, a high thrust style low pitch prop is usually best.

Suzuki and aftermarket makers offer props for this engine in several pitches. Tell us your boat length, weight and use, and we will suggest a prop to ship with the Suzuki DF9.9BTX5 for sale. A tachometer helps a lot when you test, and many remote installs add one at the helm.

Fuel and storage

Use fresh unleaded petrol of the octane listed in your owner’s manual. Avoid fuel that has sat in a tank for months. Ethanol blended fuel takes on water over time, and water is the main enemy of any fuel injected motor, including the Suzuki DF9.9BTX5 for sale.

Fit a water separating fuel filter between the tank and the motor if the boat lives on a mooring in humid weather. It costs little and catches water before it reaches the engine.

For a lay-up longer than a month:

1. Add fuel stabiliser to the tank and run the motor for a few minutes so treated fuel reaches the system.
2. Flush with fresh water.
3. Change the engine oil so acid from old oil does not sit on the bearings.
4. Change the gear oil and check it for water. Milky oil means a seal needs attention.
5. Disconnect the battery and keep it charged.
6. Store the motor tilted down if it is off the boat, or fully up if it stays on the bracket.

Following these steps every winter keeps the Suzuki DF9.9BTX5 for sale starting first time in spring.

Driving a remote 9.9 on a sailboat

Motor sailing works well with the Suzuki DF9.9BTX5 for sale. Keep the motor at mid throttle, let the sails do part of the work, and you save fuel. In a following sea, watch for the prop coming close to the surface. The extra long shaft gives you more margin than a 20 inch motor, but on a very steep wave any outboard can ventilate.

When you sail without the motor, tilt it fully up with the power tilt. A prop in the water causes drag and the lower unit can catch weed or lines. Before you start again, make sure the area around the prop is clear of ropes. Starting in gear is blocked by the shift lockout, so always shift to neutral first.

Owners who use the Suzuki DF9.9BTX5 for sale for long passages often add a remote tachometer and a fuel flow meter. Knowing your burn per hour makes passage planning easier.

Why buy the Suzuki DF9.9BTX5 for sale and not a used motor

Used 25 inch remote 9.9s are rare, and the ones on the market have often spent years in salt on a mooring. Corroded brackets, worn impellers and seized tilt units are common. A new Suzuki DF9.9BTX5 for sale comes with a factory warranty, a full service history from day one and no hidden salt damage.

You also get the current fuel injected design. Many used motors in this size are older carb engines, and parts for some are getting harder to find. With the Suzuki DF9.9BTX5 for sale, parts are easy to get through the Suzuki network in most regions.
