FourStroke · Pro XS · Verado · from 40 to 425 hp · the brand is your choice
Honda, Yamaha and Mercury are the outboards we fit on NAVY RIBs, with equal standing: the brand is your choice. On this page we tell you about Mercury as we know it, from fitting it on the transom: where it comes from, what is in the range, which power suits each NAVY, how many years of warranty it gives you in Italy and what is worth asking before you sign. The final choice is yours, and it is made at sea.
PLATE 02 — Why Mercury is on board
A RIB is judged by its transom: every kilo hanging back there changes the trim, the time to plane, the way the bow rises over the wave. Mercury has been building outboards since 1939 and its most recent engines were born with this obsession. The 350 hp Verado V10 weighs 316 kg dry, with 5.7 litres of naturally aspirated displacement and a 150 A alternator; the 50 and 60 hp FourStrokes, the ones that go on the smaller NAVYs, stop at 112 kg. These are figures taken from the technical sheets Mercury publishes, not from a brochure.
Then there is something you only understand alongside the quay: handling. With electronic throttle and shift, the joystick and the Skyhook virtual anchor, a NAVY with two Mercurys on the transom moves sideways, turns on the spot and holds its position by itself while you get the lines ready. On the 9.50 Cabin, which is born for two outboards, that argument weighs as much as horsepower. Mercury is not the only brand on board a NAVY, though: Honda, Yamaha and Mercury have equal standing with us, and we put the engine in the quote together with the boat, so you have the final figure in front of you.
PLATE 03 — Which Mercury on which NAVY · Naviglia vision
The FourStroke 40, on NAVYs up to 6 metres
NAVY 4.80 · NAVY 5.50 · NAVY 6.00 · WITHIN 6 MILES OF THE COAST
Within 6 miles of the Italian coast you may drive without a boating licence if the engine does not exceed 30 kW (40.8 hp) and the displacement limits set by law. The Mercury FourStroke 40 EFI three-cylinder is rated at 30 kW and 747 cc, the four-cylinder version at 995 cc: both within the limits. With the 40 hp we recommend NAVYs up to 6 metres.
From the 5.50 to the 6.00: up to 150 hp
NAVY 5.50 · UP TO 115 HP · NAVY 6.00 · UP TO 150 HP
Licence holders go up with the size: the NAVY 5.50 carries 9 people and accepts up to 115 hp, the NAVY 6.00 carries 10 and goes up to 150. In the Mercury range these are the four-cylinder FourStrokes: 75, 90 and 115 hp from 2.1 litres, 150 hp from 3 litres, or the Pro XS 115 and 150 for those who want more punch.
The 7.60: 200 or 250 hp recommended, a single engine
NAVY 7.60 · 200/250 HP RECOMMENDED · SINGLE OUTBOARD UP TO 350 HP
On the NAVY 7.60 we recommend a single 200 or 250 hp engine: twin engines are possible, but with two engines you lose the stern swim platforms. The right size in the Mercury range is the FourStroke V6 at 200 or 225 hp, 216 kg, or the 250 hp V8: 239 kg in the FourStroke version, 272 kg in the Verado. The ceiling for a single engine is 350 hp, which means a Verado V10.
The 9.50 Cabin: two outboards, always
NAVY 9.50 Cabin · TWO OUTBOARDS, POWER AGREED ON THE QUOTE
On the flagship the configuration is twin outboards and we agree the power together on the quote. If your choice is Mercury, the natural pair is the Verado, V8 or V10, with the 26-inch mounting spacing designed for twin installations, digital controls and the Joystick Piloting we describe further down.
The whole NAVY rangePLATE 04 — Who Mercury Marine is
Fond du Lac, Wisconsin · since 22 January 1939 · a division of Brunswick Corporation
On 22 January 1939 an engineer named Elmer Carl Kiekhaefer took over the Cedarburg Manufacturing Company, a bankrupt workshop in Wisconsin. He meant to build magnetic separators for dairies; instead he found 300 outboards abandoned by the previous owner, repaired them, sold them and discovered that this work suited him better than expected. Mercury began like that, without a plan.
Today Mercury Marine is headquartered in Fond du Lac, still in Wisconsin, is a division of Brunswick Corporation and describes itself as the world's leading manufacturer of recreational marine propulsion engines: that is the company's own claim, and we report it as such. It counts over 5,200 people and 9 production plants across the United States, Mexico, Japan, China and Belgium. For Europe the reference is Petit-Rechain, near Verviers: the declarations of conformity for the engines that reach our harbours pass through there.

This is not a museum timeline: every date below explains something you still find today on the engine hanging off the transom of your NAVY, from the colour of the cowling to the way the joystick moves the boat along the quay. The dates come from the timeline Mercury published for its 85th anniversary and from Brunswick's company history.

PLATE 07
The 2026 Mercury range, read by those who fit it
Mercury organises its outboards in families, and for a RIB from 4.80 to 9.80 metres three of them matter. The FourStrokes, from 2.5 to 300 hp, are the everyday leisure engines: simple maintenance, moderate consumption. From 40 to 60 hp they have three or four cylinders, from 75 to 150 four cylinders of 2.1 and 3 litres; then the 3.4-litre V6, from 175 to 225 hp, and the 4.6-litre V8, from 250 to 300 hp. The Pro XS, from 115 to 300 hp, are the same engines with an acceleration tune: same base, more punch coming onto the plane. The Verados, from 250 to 600 hp, are the top family: a 4.6-litre V8, a 5.7-litre V10 up to 425 hp, a 7.6-litre 600 hp V12. There are also the SeaPros for commercial work and the ProKickers for trolling, which we do not fit on NAVYs.
One thing unites them all: the fuel. The technical sheets call for a minimum of 90 RON with no more than 10% ethanol, which is the petrol you find at the harbour pump, for the FourStroke 40 as for the Verado V10. The table alongside lines up the models that make sense on a NAVY with the figures Mercury declares; where Mercury does not publish the weight, as on the FourStrokes from 75 to 150 hp, the cell stays empty. Better one cell fewer than a number made up on the spot.

PLATE 08 — Chapter 02 · FourStroke and Pro XS
From 40 to 300 hp · three, four, six and eight cylinders · 90 RON petrol
This is the family you will see most often on the transom of a NAVY up to the 7.60. The FourStroke 40 EFI comes in two versions, a 747 cc three-cylinder and a 995 cc four-cylinder: with 30 kW declared it is the engine for those without a boating licence. The 50 and 60 EFI share the 995 cc four-cylinder and weigh 112 kg, a figure you feel straight away in the trim of a NAVY 4.80 or a NAVY 5.50. From 75 to 115 hp there is the 2.1-litre four-cylinder with a 35 A alternator; the 150, from 3 litres, goes up to 60 A with a belt drive.
Above 150 the FourStroke changes architecture: the 3.4-litre V6, from 175 to 225 hp, weighs 216 kg; the 4.6-litre V8, from 250 to 300 hp, weighs 239 kg. Both have the 85 A alternator with Idle Charge, which slightly raises the idle when the batteries are low. The Pro XS are the same mechanicals with a tune for punch: the 115 weighs 163 kg, the 150 weighs 207, the 175 V6 stops at 216 and the V8s from 200 to 300 hp at 232 kg, with Transient Spark advancing the ignition at the moment of take-off. On NAVYs we recommend them to those who often go out with a loaded boat and want to plane quickly.

PLATE 09 — Chapter 03 · Verado
Verado V8 250-300 · V10 350-425 · V12 600 · 26-inch spacing
Verado is the name Mercury has given its top family since 2004. Today it means three engines: the 4.6-litre V8, from 250 to 300 hp, 272 kg with a 115 A alternator; the 5.7-litre V10, from 350 to 425 hp, 316 kg with a 150 A alternator; and the 7.6-litre 600 hp V12, the world's first twelve-cylinder outboard, which has no reason to exist on a NAVY. The V10 is naturally aspirated, with no supercharger: ten cylinders breathing on their own, with the torque it takes to lift a 9.80-metre cabin RIB out of the water.
The V10 arrived in November 2022, the first in the industry, at 350 and 400 hp; in July 2025 Mercury added the 425 and enhanced the 350, with digital throttle and shift as standard and Joystick Piloting available. According to Mercury's own declared tests the enhanced 350 is 15% faster from 0 to 50 mph than the previous 350 and 40% quieter at cruise than a 350 hp competitor; these are the manufacturer's comparisons, and we report them as such. On the 400 and 425 there is also, as an option, the dual 12 and 48 volt alternator delivering 6,000 W, which feeds the lithium banks on board without a generator. The mounting spacing is 26 inches, the same as the V8s: it is the measurement Mercury chose for twin installations and for repowers.

PLATE 10 — Chapter 04 · Handling
Digital throttle and shift · Joystick Piloting · Skyhook · Active Trim
On twin-engine NAVYs, handling is half the pleasure of owning them, or half the fear. Mercury tackles it with a chain of systems that add up. Digital throttle and shift removes the mechanical cables between the lever and the engine: smooth engagement, immediate response, controls for one or more engines. Joystick Piloting, with one hand, moves the boat in any direction, sideways or turning on the spot, reading wind, wave and current. Skyhook is the virtual anchor: one button, and the boat holds position and heading with GPS precision while you wait your turn at the fuel dock or lower the tender.
Active Trim adjusts the engine trim by itself according to speed, with five profiles and the option to override it by hand at any moment; Adaptive Speed Control holds the revs when the load or the sea changes. In 2026 came the Premier Joystick, with closed-loop speed control and the Dockhook function announced to hold the boat against the quay, and the Keyless System, keyless starting with a code or a phone and built-in anti-theft, for SmartCraft engines from 75 hp upwards. On the NAVY console all this arrives through SmartCraft and the display you choose together with the electronics.

Which Mercury for which NAVY
These are the answers we give on the phone, with the figures next to them. They hold for Mercury as for the other two brands: what changes is the cowling, not the reasoning. The right power comes from how you will use the boat, how many people you carry and where you keep it; then you try it at sea, and that is where you decide.
No licence · NAVY 4.80, 5.50 and 6.00
4.80 m RIB with centre console, up to 6 people; with a 40 hp outboard it may be used without a licence within 6 miles of the coast (Italian limit 30 kW / 40.8 hp). In the Mercury range the three-cylinder FourStroke 40 EFI has 747 cc and is rated at 30 kW; the four-cylinder version, 995 cc, also stays below the 1,000 cc that Italian law sets for a four-stroke. On the NAVY 4.80 and the NAVY 5.50 it is the engine that takes you to the cove and brings you home; on the NAVY 6.00, which carries up to 10 people, it is the minimum to start from. Licence holders go up: 60 hp at 112 kg, 75 or 90 with the 2.1-litre four-cylinders, up to the 115 and the 150 where the model's price list allows it. On these sizes the weight on the transom matters more than anything else, and the 112 kg of the 60 is a good argument.
NAVY 7.60 · 200/250 hp recommended
7.60 m RIB, up to 15 people, single outboard up to 350 hp or twin engines. On the 7.60 we recommend 200/250 hp and a single engine: twin engines are possible, but with two engines you lose the stern swim platforms, which on the 7.60 are half the pleasure. In the Mercury range the right size is the 3.4-litre FourStroke V6, 200 or 225 hp at 216 kg, or the 4.6-litre V8: 250 hp at 239 kg in the FourStroke version, 250 or 300 hp at 272 kg in the Verado version, with the 115 A alternator. The ceiling is a 350 hp Verado V10, 316 kg: it is within the model's limits, but before hanging it on a 7.60-metre transom we talk it through together, on the water.
NAVY 7.60 · twin engines
The NAVY 7.60 can also take two outboards, from 2 × 150 to 2 × 250 hp. We recommend the single, and we tell you so openly: with two engines you lose the stern swim platforms, the ones you step off for a swim. But if you go far from the coast and want the reassurance of a second engine, there is a road for you. In the Mercury range it means two FourStroke V6s at 200 or 225 hp, 216 kg each, or two 250 hp V8s, 239 kg each in the FourStroke version and 272 in the Verado: the weight on the transom doubles, and we judge the trim together, on the water. The 26-inch spacing, the same on V8s and V10s, is the one Mercury designed for twin installations. We work out the full figure for you with both roads, single and pair, with the engine fitted and tested.
NAVY 9.50 Cabin · two outboards, power agreed on the quote
Cabin RIB, 9.80 m overall and 3.20 m beam, design category B, up to 15 people, twin outboards. The 9.50 is born for two outboards, with the sunpad above the engines: we agree the power together on the quote, the brand is your choice. If your choice is Mercury, the natural pair is the Verado: V8 at 250 or 300 hp, or V10 from 350 to 425 hp with digital controls, Joystick Piloting and the 150 A alternator that feeds fridge, windlass and on-board electronics without a generator. A 9.80-metre cabin RIB is judged by its handling too: with the joystick it moves sideways and turns on the spot, with Skyhook it stays on the spot while you lower the tender. These are things a photograph cannot show: you try them.
PLATE 12
Mercury's technologies, in plain words
The acronyms in the brochures seem designed to confuse. We translate them the way we explain them in the showroom, standing at the helm, with the names Mercury uses on its own pages.
Which of these you really need depends on the NAVY: on a 4.80 with the 40 hp, weight is what counts and little else; on the 9.50, with two engines astern, joystick and Skyhook are worth more than an extra 20 hp. We talk it through on the quote, item by item, together with the helm electronics.
PLATE 13
The manufacturer's warranty, in Italy
The RIB has its own separate cover. Up to 15 years' warranty, says our price list; the engine is covered by its manufacturer's warranty. For Mercury the rules are written in the Italian-language booklet "Warranty information EMEA and CIS", with the tables dated July 2024, which we read and compared with the German edition of the same document: the values match line by line. We report them as they stand: they are Mercury's terms, not ours, and they apply to leisure use.
| Outboard | Warranty | Corrosion |
|---|---|---|
| FourStroke from 2.5 to 150 hp | 2 years | 3 years |
| FourStroke V6 175, 200 and 225 hp | 3 years | 3 years |
| FourStroke V8 200-300 and Verado V8 250-300 hp | 3 years | 3 years |
| Verado V10 350 and 400 hp | 3 years | 3 years |
For eligible products the cover extends by itself one year at a time, up to 5 years in total, on three conditions: purchase and registration within the authorised Mercury network, a documented pre-delivery inspection, and maintenance carried out according to the manual and at least once a year. The warranty only starts after the engine is registered with Mercury, which is done at the time of sale; the corrosion warranty also passes to the second owner. The 425 hp V10, which arrived in 2025, does not yet appear in the Italian table: we ask about its duration case by case. The tables, as Mercury writes, do not affect your statutory warranty rights. The United States tables are different, and do not apply here.
PLATE 14
After delivery
A Mercury does not ask for special fuel: the technical sheets call for a minimum of 90 RON petrol with no more than 10% ethanol. That is the petrol you find at the harbour pump, and it is the same fuel for the FourStroke 40 and for the Verado V10. No premix: they are all four-stroke engines. The one real rule is the annual service: once a year, according to the manual, within the Mercury network, because it is the condition that keeps the extended warranty alive and because an outboard that sleeps in winter storage needs a check before going back to sea.
The service network is Mercury's, not ours: the centres are found on its website, with the locator, and Mercury measures customer satisfaction to reward the best workshops with its Service CSI award. We do something else: we fit the engine, we try it with you at sea, we deliver the NAVY to the harbour you name or to your home and we remain the same voice on the phone afterwards. The person who advised you on the engine on the first day is the same person who answers when you have a doubt about the service.
The questions about Mercury and about engines
The questions we receive about the engine, with the answer we give in person, and those about Mercury with the figures from its own sheets. One at a time: open one and the other closes.
Honda, Yamaha and Mercury are the outboards we fit on NAVY RIBs. The brand is your choice, together with the power.
It depends on the size and on the use. With a 40 hp we recommend NAVYs up to 6 metres; on the NAVY 7.60 we recommend 200/250 hp; on the NAVY 9.50 Cabin the configuration is twin outboards, and we agree the power together on the quote. The minimum, recommended and maximum power of each model is on its page.
In Italy the licence depends on the engine: within 6 miles of the coast none is needed if the outboard does not exceed 30 kW (40.8 hp) and the displacement limits set by law, 1,000 cc for a four-stroke. The Mercury FourStroke 40 EFI is rated at 30 kW and 747 cc in the three-cylinder version, 995 cc in the four-cylinder one: it falls within both limits. With the 40 hp we recommend NAVYs up to 6 metres: NAVY 4.80, NAVY 5.50 or NAVY 6.00.
The NAVY 7.60 can be fitted with a single or twin engines, but we recommend the single: with two you lose the stern swim platforms. On the NAVY 9.50 Cabin the picture changes: it is built for two outboards, and with two Mercurys you gain the joystick and the virtual anchor.
For leisure use, from Mercury's July 2024 tables: 2 years on the FourStrokes from 2.5 to 150 hp, 3 years on the V6s, the V8s and the 350 and 400 hp Verado V10s; plus 3 years against corrosion for all of them. The cover extends up to 5 years in total if the engine is registered, has had its pre-delivery inspection and is serviced every year within the Mercury network. The RIB has its own separate cover. Up to 15 years' warranty: you will find it on the warranty page.
Petrol of at least 90 RON, with no more than 10% ethanol: the ordinary petrol of Italian filling stations. It holds for the FourStroke 40 as for the Verado V10s. No premix, because they are all four-stroke engines.
Yes, the RIB is sold with or without an engine. We assess the match with your engine on the chosen model: we need its plate data.
A NAVY is bought with or without an engine. The engine is chosen separately, by power and brand, and we quote it together with the boat, fitted and tested: so you have the final figure in front of you, with several power options. If you prefer to buy the engine yourself, that is fine too: we assess the match on the chosen model.
Within the Mercury service network, found with the locator on the manufacturer's website. The warranty starts with the registration of the engine at the time of sale, and the extension up to 5 years requires maintenance according to the manual, at least once a year. For any doubt before and after delivery, the voice on the phone remains ours.
PLATE 16 — The other brands on board
Mercury is one of the three outboards we fit on NAVY RIBs. The other two are Honda and Yamaha, with equal standing; the tube fabric is signed by ORCA of Pennel & Flipo, the helm electronics by Garmin. Every brand has its own page, with the same verified facts you have read here.
PLATE 17 — In person · Naviglia vision
You can choose an engine on a screen only up to a point: then you need to feel how the bow rises, how long it takes to plane with six people aboard, what it sounds like at cruise. Come and see the NAVYs in person. Then try them at sea. The rest we decide together, on the quote.
