Mariner Tilt Trim Motor

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.

When did Mariner become Mercury?
It was also the first probe to visit two planets. Launched on November 3, 1973, it reached Venus on February 5, 1974. Using a gravity assist from this planet, Mariner 10 first crossed the orbit of Mercury on March 29, 1974 and did so a second time on September 21, 1974.
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.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.

How do you tilt a Mariner outboard?
Down you can pull it back a little unlock drop your motor. Down. It’s simple system very straight forward. And works quite well.
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.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 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. 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.

Are Mercury and Yamaha outboards the same?
When it comes to comparing Mercury vs Yamaha you will find that both companies are a great choice. It really comes down to a matter of preference. Both companies have long histories of producing durable and quality outboard motors.
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.

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”.

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.
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.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.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.

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.
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.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. 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. 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.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.

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.
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.

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.

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.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.

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 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.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.”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.

How do you manually tilt an outboard motor?
And then press in real hard. And turn it clockwise. Just a turn or two to the left and you’ll see your motor start to slowly.
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.It is the buyer responsibility to ensure that part is the right one for his outboard. If you have any concerns regarding the suitability of the item please ask before purchase.Mariner 10 was the seventh successful launch in the Mariner series and the first spacecraft to use the gravitational pull of one planet (Venus) to reach another (Mercury). It was also the first probe to visit two planets. Launched on November 3, 1973, it reached Venus on February 5, 1974. Using a gravity assist from this planet, Mariner 10 first crossed the orbit of Mercury on March 29, 1974 and did so a second time on September 21, 1974. A third and last Mercury encounter took place on March 16, 1975. It measured the environments of both Venus and Mercury. It then undertook experiments in the interplanetary medium. Mariner 10 showed that Venus had at best a weak magnetic field, and the ionosphere interacted with the solar wind to form a bow shock. At Mercury, it confirmed that Mercury had no atmosphere and a cratered, dormant Moon-like surface.

When did they stop making Mariner motors?
In 1999, the decision was reached to end Mariner sales in the U.S. but to continue distribution internationally in markets where it remains popular. In the U.S., loyal Mariner owners were downhearted.

Mercury and mariner are the same company, both owned by the bruswick corp. Mariner was originally an australian licenced company that re-badged overseas engines and sold them locally under the ‘mariner’ brand name, mostly US made mercurys and a few Johnsons… some time ago Brunswick/Mercury bought the mariner name and took over operations. They have been sold side by side in australia ever since and obviously mercury has become more prolific with the acceptance of american brand names. The current concept is that ‘Mariner’ is the fishermans brand, as you will see from the mariner branded advertising in magazines such as “Bluewater”… Mercury is seen as the Liesure craft brand and is marketed as such, they are identical products just badged differently.
Glad i can shed some light on this topic… As far as pricing goes, the Retail for the EFI model is around the $14k mark not fitted, the non EFI is currently being sold for around the $12k mark

This question may sound strange but I have always wondered what the difference between Mercury and Mariner. Looking at the May issue of Modern Boating the specs on the 90hp EFI Fourstroke are different!The previous model 90hp four stroke Mercury/mariner was a Yamaha produced engine block, which mercury assembled and sold as their own. This was the current model up until the release of the ‘verado’ based inline four cylinder at the Sydney boat show last year. The reason for the difference in specs is that Mercury/Mariner company (tellwater) are still selling the remainder of the yamaha based engines as “mariner” and are promoting the new mercury designed and produced ‘verado’ 4 cyl under their premier “mercury brand. Eventually the new model four stroker will be badged as a mariner…same engines different stickers basicallyDo you know how long the marine engine on your boat is going to last? There are two kinds of marine engines—gasoline and diesel—and one lasts far longer than the other. On average, a marine diesel engine lasts about 5,000 hours, while a gasoline engine lasts for 1,500 hours. What does that mean for you and your vessel? Is there any way to extend the lifespan of the engine?Neglecting an engine is the quickest way to reduce its lifespan to zero. You should be regularly inspecting your marine engine, installing the proper sensors, changing the oil every 150 hours, and running the engine routinely throughout the year. Also, do not forget about the filters. Should such elements on the filter get to the engine, it will cause a dangerous accumulation and may cause rust.

The main advantage of owning a boat with a gas-powered marine engine is that they are cheap to purchase and overhaul. The downside is that these engines last about 1,500 hours, which is half the lifespan of a car’s engine.

Interestingly, outboard motors run for around 3,000-4,000 hours. Inboard engines last far longer because they come with flushing and cooling systems. On average, inboard diesel marine engines last about 5,000 to 8,000 hours, depending on maintenance.
If an engine is trying to tackle a heavier load than recommended, it is going to strain to function. That will generate more wear and tear, deducting from the overall lifespan of the engine.A boat that has a diesel marine engine is going to be far more expensive than one with a gas engine, but there is a reason for that. Diesel marine engines are crafted to be more durable: bigger cranks and crankshafts, piston cooling jets, and greater oil capacity. With proper maintenance, a diesel engine can last between 6,000 to 8,000 hours. In other words, a single diesel engine is worth the lifetime of a boat—in most cases.

As with any kind of engine, just because they can last for 8,000 hours, doesn’t automatically mean that is what will happen. Diesel and gasoline marine engines can both fail rapidly when not maintained properly. Here are some factors that subtract from an engine’s life expectancy:
For longevity, gasoline engines should be regularly operated and routinely maintained. However, that is rarely the case when it comes to boats. Most owners launch their boats a handful of times a year, and this leads to the engine sitting for a long period. Non-use puts an untold amount of strain on these kinds of engines, leading to a shorter than average lifespan.In conclusion, gasoline marine engines last around 1,500 hours, and diesel marine engines have a life expectancy of 5,000 hours. Maintenance can improve these numbers greatly, so be sure to keep up with your boat and use it often! Account for the engine type when shopping for your next boat.

Who makes the Mariner motor?
Mercury 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).
Ensure that the marine engine is cooling properly, particularly if it is a diesel engine. Nearly half of all diesel marine engines become scrap at an accelerated rate because of a poor cooling system. Diesel engines contain far more high piston compression than a gasoline engine, which generates loads of heat. If the cooling system is not functioning optimally, it can shave hours off your engine’s life.Is your boat used in salt, brackish, or freshwater? One of the worst environments is salt water, as there are elements in the water that are corrosive to metal. This is why engines often have a flushing system to keep the salt water from damaging the motor. Unfortunately, marine engines used primarily in salt water have a shorter lifespan than those used in brackish or freshwater.

Both gasoline and diesel marine engines want to be run. Letting the fuel sit or keeping the engine cool can be harmful. Therefore, run the engine long enough to get the oil and fuel warm, as that will lubricate the gears inside evenly. Keep in mind that diesel engines have a low RPM, leading to a longer warm-up time.
Although the construction of inboard and outboard marine engines is not any different, they do age at different rates. Outboard motors are mounted on the outside of the craft, creating more space inside the ship for people. On the other hand, inboard engines are installed within the boat. Both are in contact with water constantly, so the kind of water the boat is primarily used in will have an impact on these engines.Freshwater is the friendliest towards your marine engine, as there is no salt to cause corrosion. Marine engines that are used only in freshwater are going to have the longest lifespan.

Mercury Outboards – Durable. Reliable. Powerful.

Mariner was originally built under a joint venture with Yamaha, which was ended by the Federal Trade Commission’s ruling that the agreement hindered competition. By the early ’80s, Mariner and Mercury were becoming more similar than different. When electronic fuel injection was introduced in 1986, the transition was complete; the two outboards were mechanically the same.
An expert R&D team that included brothers Stan Hayes and Doug Hayes — winning racers for Polaris — and engine specialist Les Cahoon designed a competitive snowmobile for the 1973-74 season called the Sno-Twister that went on to dominate racing and change public perception of the Mercury snowmobile brand.However, the economies of scale did not bode well for a two-brand strategy. With less risk of losing U.S. sales through a larger number of committed boat builders, the savings in manufacturing and marketing costs for a single outboard brand would be significant.A new design and liquid-cooled engine for 1976 powered Sno-Twister drivers to wins in every stock, junior and women’s class, and all but one Mod Stock class, while Stan Hayes qualified for the World Championship final. But it wasn’t enough.

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.
In the mid 1990s, the future viability of a second outboard brand was debated. While the distribution issue lessened as more boats and motors were sold as a package by U.S. boat builders, Mariner enjoyed a far larger market share internationally than at home. Still, the perception remained that OMC would enjoy a “two-to-one advantage” with its dual outboard brands.It appears you are using Internet Explorer, an unsupported web browser.

Rival engine builder Outboard Marine Corporation (OMC) sold two outboard brands, Johnson and Evinrude. While Mercury enjoyed equal market share in the category, it was thought that a second outboard line could boost Mercury Marine’s distribution, both in the U.S. and internationally.
