 changed the corporate climate, and Kiekhaefer sought a government contract to design two-man air-cooled chainsaws. Army engineers were 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 inches (609.6 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.

Post-war history


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 motor at the 1947 New York Boat Show called the "Lightning" or KE-7.

Kiekhaefer decided to promote his company by owning a NASCAR

1950s through 1970s


In 1957 Kiekhaefer started testing at a Florida lake he called "Lake X" in order to keep the location secret. Later that year the company designed a new inline 6-cylinder 60 hp motor 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.

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.

Two Mark 75 motors set an endurance record by running non-stop for over 50000 miles (80,467 km) over 68 3/4 days on Lake X. The motors were refueled as they ran, and averaged 30.3 miles per hour.

When Mercury's top-of-the-line model Merc 800 was introduced, direct reversing as standard equipment was 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.

In 1961 the company merged with the Brunswick Corporation

.

The company introduced the MerCruiser stern-drive line at the 1961 Chicago Boat Show. The line would later take over 80 percent of the world market. http://northamerica.mercurymarine.com/about/heritage.php

In 1966, 6-cylinder Mercury models featured the introduction of electronic ignition, another first that eventually became an industry standard.

Carl Kiekhaefer resigned as President of Kiekhaefer Mercury in 1969, and the name was changed to Mercury Marine. 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 1971, they came out with the Rocket and Lightning models. 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 lightning-fast sled with slide suspension (as opposed to bogie wheel). 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. Mercury was renowned in the 1970s as one of the best racing and performance snowmobile manufacturers, as well as an industry leader in marine engine production.

Today


Today, Mercury product brands include Mercury, Mercury Racing, MerCruiser, and Mariner outboards (sold outside the U.S.). Outboard sizes range from 2.5 hp to 350 hp. MerCruiser sterndrives and inboards range from 100 to 450 hp and Mercury Racing outboards produce up to 350 hp and sterndrives to 1200 hp. Subsidiaries include Mercury Precision Parts and Accessories as well as Mercury propellers and Mercury Jet Drives. In the U.S. Mercury outboards, from 30 hp and below are rebadged Tohatsus.
Mercury has recently developed a processor enhanced line of outboards called the "Verado" outboard engine http://northamerica.mercurymarine.com/engines/outboards/verado/. The "Verado" system integrates the outboard into an entire system, including "fly-by-wire

In 2007 Mercury Marine began selling its Zeus drive system http://northamerica.mercurymarine.com/otherproducts/smartcraft/smartcraftinaction/zeus.php. 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 AnchorTM which will keep a vessel on a fixed heading within a tight range. The system might be called all weather as it will keep a heading in strong currents and winds.

Mercury Marine is one of the world’s leading providers of marine propulsion. As $2.3 billion division of Brunswick Corporation, Mercury and its 6,200 employees worldwide provide engines, boats, services and parts for recreational, commercial and government marine applications.

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, CO.

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 hp. SeaCore is designed for a wide variety of vessels operated in or moored on saltwater.
