40 Hp Mercury Outboard

PLEASE NOTE: We charge € 50 transport costs for shipping. We make the engine ready to sail and therefore it cannot be included in the regular shipment.The company can be traced back to 1922, when the Takata Motor Research Institute began carrying out research into various forms of internal combustion engines. Research and development of high-speed, portable engine generators and radio-controlled generators began immediately; these were brought to production in 1930. During the 1930s and 40s, Tohatsu consolidated its product line and moved its corporate office to Tokyo. Among its products in the 1930s were railcars for the Ministry of Railways.In 1950, production and sales of motorcycles began. 1955 brought aggressive growth to Tohatsu. Capital increased to 150 million yen and production on a new line of engines started. Sales offices were established in Fukuoka, Nagoya, Tokyo, Sendai and Sapporo. Dealerships were set up throughout Japan.

Tohatsu Corporation (トーハツ株式会社, Tōhatsu Kabushiki-gaisha) is a Japanese company manufacturing and selling outboard motors, pleasure boats, portable fire pumps, small fire trucks, pumps for construction and drainage, and refrigeration units for transportation. It also does real estate property management in Japan.In the mid-1950s, the company held the top market share, with 22 percent of the Japanese motorbike market. They also manufactured racing motorcycles and achieved success in Japan and abroad. Financial problems led to the discontinuation of Tohatsu motorcycle production in 1964.

As well as marketing outboards under its own brand, Tohatsu outboards are rebadged and sold as other brands. In 1988 Tohatsu and Brunswick Corporation set up a joint venture named Tohatsu Marine Corporation to produce outboards for Mercury Marine. All Mercury outboards with less than 30 HP are rebranded Tohatsus.

1956 ushered in the production of the first Tohatsu Outboards (1.5 hp). Since then, Tohatsu outboards have served a variety of marketplaces: commercial fishing, military, marine transport, surf life saving, recreation and competition racing. They are the second largest producer of outboards in the world.
In 1994, Suzuki unveiled the first of their four-stroke outboard motors, the DF9.9 and DF15.. The company subsequently released the DF60 (which featured an electronic fuel injection system) in 1997, and the DF300 in 2006 being the industry’s first 300HP V6 4-stroke outboard. In 2017, Suzuki Marine debuted the DF350A outboard motor, under the slogan: “The Ultimate 4-Stroke Outboard”. The DF350A engine received the 2017 IBEX Innovation Award of the National Marine Manufacturers Association (NMMA).After manufacturing their first outboard motor in 1965, the 5.5 horsepower D55, Suzuki continued producing outboard motors. in 1987, the two-stroke, V6 DT200 Exante engine won the company’s first accolade: the “Most Innovative Products” award from the National Marine Manufacturers Association (NMMA) of the U.S.

Suzuki Marine is an international company that designs and manufactures outboard motors. A subsidiary of the Japanese multinational motor corporation Suzuki, Suzuki Marine has locations in America, Asia, Europe, Africa and Oceania.
Suzuki outboards have won several of the “Innovation Awards” awarded by the National Marine Manufacturers Association (NMMA). The NMMA is a trade association representing boat, marine engine and accessory manufacturers in the U.S. Listed below are the Suzuki outboard models that have won the “Innovation Award”:

Suzuki Marine produces two-stroke and four-stroke outboard engines ranging from 2.5 horsepower to 350hp. Suzuki Marine outboard motors are manufactured at the Tokoyama facility in the Aichi prefecture of Japan, and in factories in several countries abroad.
Michio Suzuki was born in Hamamatsu, Shizuoka Prefecture, Japan on February 10, 1887. While he worked as a young apprentice carpenter, the textile industry in the Enshu region where he lived was booming. Suzuki became an inventor and businessman, and began his career manufacturing looms. In 1909, he founded Suzuki Loom Works. In 1920, Suzuki established the Suzuki Looming Manufacturing Co. as a joint-stock company. The company successfully established itself as a supplier of looms in Japan’s lucrative silk industry, but damage to factories sustained during the World War II and the collapse of the cotton industry in the 1950s prompted Suzuki to expand into other areas of manufacturing.When the second outboard motor, DT5, was produced in 1977, the corporation marketed it in the U.S. under the new brand Suzuki Marine. In 1999 the company produced their first foreign-made outboard motor in Thailand by the Thai Suzuki Motor Company.Several decades later the company manufactured its first automobile, as civilian passenger vehicles were deemed a non-essential commodity in Japan due to tough economic conditions following World War II. Suzuki began developing products that were specifically needed at the time. This led to the release of the company’s first motorised bicycle in 1952, entering them into the motor industry. This first motor formed the foundation of Suzuki’s future in designing engines. In January 1954, the company changed its name to Suzuki Motor Co., Ltd. A year later, the first Suzuki automobile, Suzulight, went on sale. In 1965, the company marketed their first Suzuki outboard motor, D55.

Where are 40 hp Mercury outboards made?
China Mercury Marine is a marine engine division of Brunswick Corporation headquartered in Fond du Lac, Wisconsin. The main product line is outboard engines. It also produces the MerCruiser line of sterndrives and inboard engines. Some manufacturing is in Fond du Lac, while 40-60 HP engines are made in China.
Founded by Japanese inventor Michio Suzuki in the city of Hamamatsu in 1909, the company has built engines, motorcycles, automobiles, ATVs and outboard motors, building their first outboard motor in 1965. The Suzuki Marine brand was formed in 1977 to market outboard motors exclusively to the U.S., and currently has factories and distributors in several countries. In 2017 the Suzuki Motor Corporation was the fourth largest automaker by volume in Japan.Mercury’s first 6-cylinder engines featured “direct reversing”. Instead of a lower unit with forward, neutral and reverse gears, its lower units were more compact, with only drive and driven gears, and no submerged shift mechanism required. Reverse was selected by turning off the engine and restarting it in opposite rotation, and neutral by simply switching off. Mark 75s, like many of their smaller brethren, were available in an “H” (high speed) version. Many of these large H engines sported open headers for competition and produced 90 horsepower from 60 cubic inches. Two totally stock Mark 75s set a world endurance record on Lake X, running 50,000 miles at an average of 30.3 mph, while being re-fueled on the fly. The boats were stopped only for driver changes and standard maintenance. After the record-setting run was completed, the motors were torn down and inspected for wear. They were found to be well within factory tolerances.

In 1957 Kiekhaefer started testing at a Florida lake he called “Lake X” to keep the location secret. Later that year the Kiekhaefer Mercury company designed a new inline 6-cylinder, 60 cubic inch, 60 hp (45 kW) engine named “Mark 75”. Like its 2- and 4-cylinder brethren, the Mark 75 featured internal reed valves. The reed valve blocks served as intermediate main bearings. Because the valves occupied space already necessary for the main bearings instead of mounting to an extension of the crankcase, crankcase volume was minimized, resulting in a higher crankcase compression ratio, and more power in proportion to displacement than the competition.In 2007 Mercury Marine began selling its Zeus drive system. Developed by Mercury and its joint venture company Cummins MerCruiser Diesel (CMD), the Zeus drive is a dual-engine pod drive system. Some of the most notable benefits from this class design for boaters will be enhanced helm control. While underway an automated trim control feature simplifies operation. Also, Zeus includes Skyhook Electronic Anchor which will keep a vessel in a fixed location within a tight range. The system might be called all weather as it will maintain location in strong currents and winds.For 1962, the Merc 1000 became the new top of the line in line 6, offering 100 hp. It was somewhat of a sensation. It also introduced the new “Phanton Black” paint scheme which soon spread to the entire line and became famous.Why these Mark engines (and other Mark engines) carried number names which were not horsepower ratings, not displacement numbers, and not consistent from one motor to another, is a real mystery. Why was the 20 hp Mercury a Mark 25, and the 40 hp Mercury a Mark 55, while the 30 hp job was the Mark 30? No one really knows.

Kiekhaefer decided to promote his company by owning a NASCAR and AAA team. The team dominated NASCAR Grand National (at one point winning 16 straight races), even though it only competed in 1955 and 1956. The team won the 1955 and 1956 NASCAR championships with drivers Tim Flock and Buck Baker. One of Kiekhaefer’s innovations was using dry paper air filters, which are still standard in automobiles today.

At present, Mercury product brands include Mercury, Mercury Racing, MerCruiser, and Mariner outboards (sold outside the U.S.). Outboard sizes range from 2.5 horsepower (1.9 kW) to 600 horsepower (450 kW). MerCruiser sterndrives and inboards range from 135 to 430 horsepower (320 kW) and Mercury Racing outboards produce up to 450 horsepower (340 kW) and sterndrives to 1,750 horsepower (1,300 kW). Subsidiaries include Mercury Precision Parts and Accessories as well as Mercury propellers and Mercury Jet Drives. Mercury outboards 30 hp and below are manufactured by Tohatsu in Japan.

Carl Kiekhaefer resigned as President of Kiekhaefer Mercury in 1970, and the name was changed to Mercury Marine in 1972. During this time, Mercury produced snowmobiles, like many other companies in the late 1960s. The first ones incorporated a 250 cc two-man chainsaw engine.In 1975 Mercury introduced 340cc and 440cc versions of the Sno-Twister and both were dominant at the track. 1976 saw a change in the Sno-Twister, this time 250cc, 340cc, and 440cc versions were all introduced. These were radical for their time and were the result of Mercury Sno Pro sleds developed and raced the previous year. These 1976 sleds were featured water-cooled Kohler engines. The chassis were small, lightweight, very low profile, with curved handlebars and seat cushions that were designed for left turns (oval tracks). Of course, there were also smaller Mercs during both the K era and the Mark era, such as the “Super 5” and later, such engines as the “Mark 6” and the “Mark 10”. Mercury Marine is a marine engine division of Brunswick Corporation headquartered in Fond du Lac, Wisconsin. The main product line is outboard engines. It also produces the MerCruiser line of sterndrives and inboard engines. Some manufacturing is in Fond du Lac, while 40-60 HP engines are made in China. Smaller engines are Tohatsus that have been rebadged.In 1975 and 1976 Mercury also produced the Trail Twister snowmobiles which were available in 340cc and 440cc which were fan-cooled. These were some of the fastest lake racers around in their day. This started off a new era in snowmobile construction for the whole industry and the sled’s basic format set up what is seen today in modern snowmobiles.

World War II changed the corporate climate, and Kiekhaefer sought a government contract to design two-man air-cooled chainsaws. Army engineers had been unable to design a lightweight motor. Kiekhaefer designed a new lightweight chainsaw in 2 months. The Kiekhaefer powered chainsaw was able to cut through a 24-inch (610 mm) green log in 17 seconds, while it took the nearest competitor 52 seconds. Mercury was awarded the contract, and was the world’s largest chainsaw manufacturer by the end of the war.In 1971, they came out with the Rocket and Lightning models of snowmobiles. These sleds combined aluminum tunnels with Canadian Curtiss Wright (CCW) engines. The Rocket was a 340, and the Lightning a 400 with electric start. By 1972, Mercury started production of the Hurricane, a more modern snowmobile with optional slide rail suspension (as opposed to bogie wheel). In 1974 Mercury introduced the Sno-Twister 400cc snowmobile designed primarily for racing. It featured a Kohler free-air engine and succeeded in dominating the 400cc class.

Mercury has recently developed a processor-enhanced line of outboards called the “Verado” outboard engine. The “Verado” system integrates the outboard into an entire system, including “fly-by-wire” steering and advanced diagnostics. Verado engines are available in 250 hp and 300 hp (V8), 350 hp and 400 hp (V10, introduced in 2022), and 600 hp (V12) as of early 2021.
Kiekhaefer Mercury foresaw that the average American’s interest in boating would increase after the war. Kiekhaefer introduced a 19.8 cubic inch, 10 horsepower (hp), two-cylinder alternate firing design engine at the 1947 New York Boat Show called the “Lightning” or KE-7. This engine, also called the “Super 10”, actually developed around 14 horsepower. Its designation was updated to KF-7 for 1949. For 1951 the engine block, though still displacing 19.8 cubic inches, was updated a great deal, and given the name “Hurricane”. The 1951 kg-7 “Super 10” featured this engine, which developed around 16 horsepower. For 1952, this model was updated with a “forward, neutral, reverse” gearset, and a twist grip throttle. It was renamed “Cruiser” at this point, and no longer called “Super 10”. This engine later became the heart of the “Mark 25”, of the mid to late fifties. Initially rated at 16 horsepower, this engine was soon beefed up to 20. There was also an “H” version, which produced more power but carried no rating. “H” version Mercurys were mostly used for racing.With Mercury Marine outboards typically having smaller displacement per horsepower and better fuel economy than the competition’s motors, an ad ran in publications showing a Mercury-powered boat pulling an elephant on a large ski-like platform. The caption simply read “Mercury, pulls an elephant. Runs on peanuts.”

When Kiekhaefer Mercury’s top-of-the-line, 80 horsepower (74 cubic inch) model “Merc 800” was introduced for 1960, direct reversing as standard equipment was optionally replaced by full forward, neutral and reverse gear shifting, as on Mercury’s 2- and 4-cylinder models, and “thru-hub” exhaust was introduced. Previously, as with other outboard brands and Mercury’s smaller models, exhaust exited from a chute at the rear of the cavitation plate above the propeller. Thru-hub exhaust was claimed to be more efficient by omitting the added drag of an exhaust chute, and using the low-pressure area necessarily created by the gear housing and propeller moving through the water to assist in exhaust evacuation. Over the next several years, thru-hub exhaust became a standard feature of all Mercury models, and later was adopted near industry-wide for both outboards and stern-drives.
For 1958, an enlarged version of this engine was introduced. The new “Mark 78” had 70 horsepower with 66 cubic inches of displacement. No “H” version was offered. Also in 1958, a stock Mark 75H set a new world speed record for outboard motors, of 107 mph.Mercury’s brand portfolio includes Mercury and Mariner, Mercury MerCruiser sterndrives and inboard engines, MotorGuide trolling motors, Mercury and Teignbridge propellers, Mercury inflatable boats, Mercury SmartCraft electronics, and Mercury and Quicksilver parts and oils. MotoTron electronic controls was also a part of Mercury Marine, but as of October 2008 Brunswick Corp. sold MotoTron and its intellectual properties to Woodward Governor of Fort Collins, Colorado.

Is Mercury made by Tohatsu?
As well as marketing outboards under its own brand, Tohatsu outboards are rebadged and sold as other brands. In 1988 Tohatsu and Brunswick Corporation set up a joint venture named Tohatsu Marine Corporation to produce outboards for Mercury Marine. All Mercury outboards with less than 30 HP are rebranded Tohatsus.
Due to a rather large gap between the Mark 25 (20 hp) and the Mark 55 (40 hp), Mercury brought out the 4 in line, approximately 30 cubic inch “Mark 30” (30 horsepower) engine for 1956, and produced versions of its “TurboFour” engine for several years. It, too, was available as an “H” version, producing much extra horsepower for racing and sporting use.The Kiekhaefer Mercury company began in 1939 when engineer Carl Kiekhaefer purchased a small outboard motor company in Cedarburg, Wisconsin. Kiekhaefer’s original intention for the Kiekhaefer Corporation was to make magnetic separators for the dairy industry. The purchase included 300 defective outboard motors. Kiekhaefer and a small staff of employees rebuilt the motors and sold them to Montgomery Ward, a mail-order company. The motors were much improved, so the buyer purchased more. Kiekhaefer designed motors that withstood the elements better than his competition and called the motor Mercury (taking advantage of the “Mercury” Motor Car popularity at the time) whilst adopting the logo of the Roman god Mercury.

SeaCore is a brand of sterndrive marine propulsion systems manufactured in the United States by MerCruiser. The SeaCore engine design utilizes materials, technologies, and systems, created specifically for Mercury Marine, to prevent galvanic corrosion within its engine, transom and drive. SeaCore propulsion includes models generating between 220 and 425 horsepower (317 kW). SeaCore is designed for a wide variety of vessels operated in or moored on saltwater.

In 1949, the company also introduced its first large outboard, the approximately 40 cubic inch, 4 cylinder in line, “Thunderbolt”. This engine was rated at 25 horsepower, but actually put out around 28. There was soon an “H” version designed for high rpm use. This version put out nearly 40 horsepower, while being rated at “25+”. The Thunderbolt engine benefited from upgrades and updates, eventually becoming the Mark 40, Mark 50, and Mark 55 engines of the mid and late fifties. All of these were rated quite accurately at 40 horsepower. The Mark 55H (high speed) developed more, but carried no rating.High-displacement, four-cylinder, single-overhead-cam design delivers optimum power and a smooth ride. Great for aluminum tiller, aluminum console, inflatable rigid hull (RIB) and soft hull, watersports, and fish & ski boats.

The tachometer informs the operator of potential problems such as low oil pressure, low battery, and overheat, through the built-in warning lights. (For models equipped with a tachometer)
The multi-function tiller handle features an ergonomically designed shift lever for easy and convenient shifting as well as a longer throttle grip with 110 degrees rotation for easier maneuverability. All controls on the new multi-function tiller are conveniently located on the handle for easy access and control. More specifically, the gear shift, throttle control, trim switch, safety lanyard cord, TLDI warning lights, and electric start key switch are all integrated in the tiller handle.Use our handy database to locate the dealers in your area!
