for both outboards and stern-drives. 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 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. 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. 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 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. 1970s 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. 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). 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
