Suzuki 90 HP DF90AWQH Outboard Motor

Description

We have the Suzuki DF90AWQH for sale new in the factory crate. It is Suzuki’s 90 horsepower Cargo Series tiller four stroke with a 20 or 25 inch shaft, a tiller handle, gas assisted tilt and electric start, finished in Pearl Nebular Black. It is built for working boats: fishing boats, pangas and cargo boats run by a skipper standing at the stern.

We sell new outboards to private owners, fishing operators, boat builders and dealers, and we ship worldwide. Tell us where your boat is and we send you a delivery quote before you commit to anything. This is where the Suzuki DF90AWQH for sale earns its keep.

Below you will find the full specs, what the model code means, the boats it suits, rigging, maintenance and the questions buyers ask us most. It is a long page on purpose. A motor like this is a serious purchase and most people want the details first.

Suzuki DF90AWQH for sale: Specifications

Numbers can move a little between production runs, so the paperwork in the crate is the final word. Suzuki keeps the current figures on its DF90AWQH page on Global Suzuki if you want to compare models side by side.

What the Model Code on the Suzuki DF90AWQH for sale Means

Suzuki model codes look confusing until someone explains them once. DF is Suzuki’s four stroke prefix and 90 is the horsepower. The A marks the A generation of this engine. WQH is the code for the Cargo Series tiller version, with a tiller handle and gas assisted tilt.

What you do not see in the code matters too: there is no Z, so it is standard rotation.

The Suzuki DF90AWQH for sale Is Built for Work

The DF90AWQH is the first motor in Suzuki’s Cargo Series, a line made for commercial users and fishermen. It is a 90 horsepower tiller motor built to run all day, every day.

It uses the 1.5 litre inline four from the DF90A, with an offset driveshaft and a two stage gear reduction to 2.59:1. That gearing keeps the prop turning with heavy loads on board. Plenty of buyers send us their boat details before ordering the Suzuki DF90AWQH for sale, and we like that.

The working features are what set it apart. A gas assist tilt lets you lift and trim the motor with little effort. The tiller handle adjusts to three levels. A sub water inlet keeps cooling going when algae or weed block the main intake. Stainless rivets on the tilt system, water in fuel protection and an anti-corrosion finish help it survive hard use.

Gas Assist Tilt

Instead of a power trim motor, the Suzuki DF90AWQH for sale uses a gas assisted tilt system. You can raise and lower the motor quickly with very little effort, even on the water. Fewer electrics also means fewer things to fail in a hard working boat.

Boats That Suit the Suzuki DF90AWQH for sale

Fishing boats and pangas

Open work boats where the skipper stands at the stern.

Cargo and passenger boats

Boats that carry goods or people between islands, villages and river towns.

Aquaculture and farm boats

Boats working fish farms and shellfish beds.

Utility boats

Any open boat where a tiller makes more sense than a console.

How the Suzuki DF90AWQH for sale Feels on the Water

Steering a 90 horsepower motor with a tiller sounds heavy, but the Suzuki DF90AWQH for sale handles well thanks to its adjustable handle and smooth throttle.

Loaded with nets, fish or cargo, it keeps pushing without bogging, which is what the gearing is for.

Running a Tiller Motor This Size

The Suzuki DF90AWQH for sale is meant for single engine working boats. The skipper sits or stands beside the motor and steers with the handle, which gives a direct feel for the boat and leaves the deck clear for nets, fish boxes or cargo. Make sure there is a solid place to brace your legs, because a 90 swings with some force.

Colour and Finish

Black is the standard Suzuki finish and suits almost any boat. If you want a white cowl to match a white hull, ask us about the W version of this motor. The engine underneath is the same. Keep that in mind when you set up the Suzuki DF90AWQH for sale.

Rigging the Suzuki DF90AWQH for sale

A tiller motor needs very little rigging. Bolt it to the transom, connect a fuel line with a water separating filter, wire in a battery with good cranking amps and you are close to done. There is no console, no control box and no steering system to buy.

Set the tiller handle to the height that suits you. Suzuki gives you three positions, which helps whether you sit on a thwart or stand.

Mount the motor so the anti-ventilation plate sits roughly level with the bottom of the hull, then fine tune after a test run. If the prop blows out in turns, drop it a hole. If there is a lot of spray and drag, raise it. The 12 V, 27 amp alternator keeps electronics charged on a normal day.

Transom Height and Shaft Length

This motor comes in more than one shaft length: L (20 inch) or X (25 inch). Measure from the top of the transom to the bottom of the hull at the centreline, send us the number and we will match the shaft. Getting this right is the single most important part of ordering an outboard. That applies to the Suzuki DF90AWQH for sale as much as any motor.

Suzuki DF90AWQH for sale or a Remote DF90A?

The DF90A remote models need a console, controls and steering. They suit leisure boats and boats with a helm station.

The Suzuki DF90AWQH for sale is for open working boats where the operator stands or sits at the motor. It skips the cost of controls and steering, and the tiller gives direct feel.

Who Buys the Suzuki DF90AWQH for sale From Us

Most of our buyers are owners who want a reliable motor and a fair price without dealer games. Next come fishing and charter operators repowering a working boat, and then boat builders and dealers who need stock to rig new hulls. The feedback after a season is nearly always the same: it starts every time, it is easy on fuel compared with what they had, and it has needed nothing beyond normal servicing.

Day to Day Ownership

Good outboards fade into the background. You stop thinking about the engine and think about the fishing or the family instead. The Suzuki DF90AWQH for sale starts on the first turn, idles cleanly with no choke and does not foul plugs after a slow morning. Keep up with flushing and servicing and it will keep doing that for years.

Breaking In the Suzuki DF90AWQH for sale

Follow the break-in in the owner’s manual. In short: vary the revs during the first hours, do not hold it at full throttle for long, and change the engine oil and filter at the first service. A motor broken in gently uses less oil and runs smoother for the rest of its life.

Give the gearcase its first oil change at that service too. It flushes out the fine metal from new gears bedding in.

Keeping the Suzuki DF90AWQH for sale Healthy

Nothing about this motor needs special tools for routine care. Stick to a simple routine:

• After every trip: flush, rinse and check the tell-tale stream.
• Every month in use: look at the anodes, the prop and the fuel filter bowl.
• Every 100 hours or yearly: engine oil, oil filter, gear oil and a grease of every fitting.
• Every two years or so: water pump impeller and thermostat check.
• At the major service: plugs, fuel filter and a valve clearance check if the manual calls for it.

The timing chain runs in oil and does not need replacing like a belt. That is one less big bill to plan for.

Matching the Motor to the Boat

The right motor is the one your boat is rated for, carrying the load you normally carry. Check the capacity plate for maximum horsepower and engine weight, then think about how you use the boat. Heavy loads, rough water and long runs all favour running close to the maximum rating. Light boats and calm water give you more freedom. If the numbers do not line up with 90 HP, ask us and we will point you to a better match. If you are unsure, send us a photo of the transom and we will check the Suzuki DF90AWQH for sale is the right fit.

Fuel Use and Running Costs

Four stroke fuel injection makes the Suzuki DF90AWQH for sale far more economical than the old two stroke tillers many work boats still run. Suzuki says the same.

Parts are easy to find in most countries because Suzuki sells a lot of outboards. Filters, impellers, anodes and plugs are normal stock items. That keeps the long term cost of owning the Suzuki DF90AWQH for sale sensible.

Keep the Fuel Clean

Most problems people blame on the engine start in the tank. Water, old fuel and dirt in the lines will make any motor run badly. Change the water separating filter every season, drain the bowl if you see water and use fresh fuel. In hot, humid places keep the tank as full as you can when the boat is parked, so there is less room for condensation.

Treat the fuel well and fuel injection rewards you with easy starts and smooth running.

Getting the Prop Right

A motor is only as good as its prop. With the Suzuki DF90AWQH for sale you want to land in the 5,300 to 6,300 rpm band at wide open throttle with a normal load. Too many revs means the pitch is too low. Too few means it is too high. The usual pitch choice for this motor is a 13 to 25 inch pitch range.

Look at Suzuki genuine parts and accessories for propellers and service parts, or ask us. We are happy to suggest a pitch if you send the boat make, length and typical load. Many repeat customers come back for a second Suzuki DF90AWQH for sale on another boat.

Running Slow All Day

Anglers spend a lot of time at idle or just above it. A fuel injected four stroke handles that well. There is no smoke, no oil fouling and no hard restart after a long drift. Keep an eye on the battery if you run a lot of electronics at low revs, and give the motor a short run at higher revs on the way home to clear it out.

Instruments for the Suzuki DF90AWQH for sale

Suzuki’s digital gauges read engine data straight from the motor, including fuel flow and service reminders. If you prefer, plain analogue tach and trim gauges work too. Whatever you fit, run tidy wiring with proper fuses. Good wiring now saves a lot of headaches later.

Batteries and Wiring

Use a marine starting battery with good cranking amps, keep the terminals clean and tight and fit a battery switch. If you run lots of electronics, a second house battery with a charging relay keeps the starting battery fresh. Corrosion on terminals and loose earth wires cause more no-start calls than anything inside the engine.

Salt Water Care

Flush after every salt trip. Rinse the outside, wipe salt off the cowl and spray a corrosion inhibitor under the cowl now and then. Suzuki’s anti-corrosion finish is tough, but salt finds any gap if you ignore it. If the boat lives in the water, tilt the motor up when you leave it. The Suzuki DF90AWQH for sale is covered here too.

Hot and Cold Climates

In hot climates, check the tell-tale stream often and keep the cooling passages clean. Warm, silty water is hard on impellers. In cold climates, fuel injection makes starting easy, but drain the motor and winterise it properly before a freeze.

Towing and Ramp Habits

Long road trips are harder on an outboard than most people think. Use a motor support bracket rather than resting the motor on the tilt ram, and check the bolts on the transom clamp or mounting after the first few trips. At the ramp, back in, lower the motor, start it in the water and watch for the tell-tale before you drive off the trailer.

Back home, flush it while you wash the boat. Same routine every time and it becomes second nature. That is a big part of why people choose the Suzuki DF90AWQH for sale.

Laying It Up

For short breaks, flush, drain and tilt up. For a long lay up, run stabilised fuel through the system, change the engine and gear oil, fog the engine if the manual calls for it, grease every fitting and keep the battery charged. A cover keeps sun and bird mess off the cowl.

Simple Fixes Before You Call a Mechanic

No crank: lanyard clipped on, lever in neutral, battery charged, terminals tight.

Hard starting: firm primer bulb, tank vent open, no water in the separator, fresh fuel. Owners of the Suzuki DF90AWQH for sale tell us the same thing again and again.

Overheat alarm: stop, tilt up and look for a plastic bag or weed over the intake. Check the tell-tale stream when you restart.

Low top speed: check the prop for damage, check the mounting height and make sure the boat bottom is clean.

Rough running: old fuel and dirty filters cause most of it. Start there. It is one of the reasons we keep the Suzuki DF90AWQH for sale in stock.

Carry These on Board

A spare kill cord, a spare prop with nut and washer, a fuel filter, a couple of spanners, a radio and a torch. Add a tow line and an anchor that holds. It sounds basic, but most bad days on the water start with something small.

Tips for a Repower

A repower is the best chance you will get to fix the things you cannot reach with a motor on the back. Check the transom, replace old fuel hoses and the primer bulb, clean or replace the tank pickup and fit a new water separating filter. Fresh fuel lines and clean fuel make a new motor happy from the first day.

Measure the transom height before ordering so the shaft length is right. It is the one mistake that is hard to fix later. You get all of that with the Suzuki DF90AWQH for sale.

Two Stroke to Four Stroke: What Changes

If your old motor was a two stroke, a few things will feel new. You will stop buying two stroke oil. The motor will idle cleanly without smoke. Fuel bills drop, often a lot, especially at cruise. You will also notice the extra weight on the transom, so set the trim and mounting height carefully on the first runs.

Service changes too. Instead of plugs and oil injection checks, you will be changing engine oil and filters like a car. It is simple, and most owners prefer it.

Mistakes We See Buyers Make

The most common one is the wrong shaft length. Measure the transom before ordering, not after the crate arrives. The second is under-propping, which lets the motor over rev and wastes fuel. The third is skipping the rigging list, then finding out the old controls or harness do not fit the new motor. And the last is ignoring the boat’s capacity plate. A motor heavier or more powerful than the hull is rated for is a real safety problem. Ask us if you want photos of the Suzuki DF90AWQH for sale before it ships.

The First Year of Ownership

Year one is easy. Follow the break-in, get the first service done on time and keep a log of hours. Look at the prop and anodes now and then, and flush after every salt trip. Before winter or a long break, do a proper lay up. If you do those simple things, the motor will reward you with years of trouble free running.
