A fool is anyone who calls another stupid without asking a few questions first...
Yep, zukis are OMCs, and some Mercs are Yammis, and (back in history):
West Bend became
Chrysler, which became
Force, which later became some
Mercury models.
Scott-Atwater became
McCullough and made a bunch of motors as
Sears, Gamefisher, and
Eska. Are you seeing a trend?
West Bend and Elgin sold zillions of motors through Sears - from the 50s through the 60s - then replaced by other names - see above.
But here is a great story:
Chris-Craft got in the fray in the 40s and 50s and sold Chris-Craft outboards - called the "World's finest outboards" - they were available in models from 5-10 HP. CC hired a bunch of Mercury engineers for their designs and Mercury sued. Mercury won, and CC was forced out of the outboard business. But the business did not go totally away, the Oliver Corporation from Battle Creek (remember CC was based in Algonac and Holland, MI) begain building versions of the CC design.
So Mercury became Chris-Craft, but Chris-Craft could not make Mercurys, so Chris-Crafts became Olivers. But it's not over yet: George Martin, creator of Martin Outboard Motors, left Scott Atwater to start Martin Motors, a division of National Pressure Cooker Company. Their claim to fame was the poppet valve induction system used on these outboards. (Other two-cycle outboards had long utilized reed valves to meter fuel mix into the crankcase.)
However, Martin lost the poppet-valve technology claim, and the 35-hp Oliver Olympus sported poppet-valve technology. However, the industry leaders of OMC, Mercury, and even Scott McCulloch forged ahead with larger outboards, and Oliver could not keep up.
Oliver struck a deal with Perkins Ltd., (the diesel engine folks), and the motors became Perkins, then later Sunbeam, and finally Rootes before ceasing production - the poppet valve technology has never returned, but could be very efficient for a 2 cycle engine.
And one last one:
Muncie - or, more correctly Muncie Gear Works, or MGW - also made outboards from the 30s. In fact, Muncie took Johnson on and won in the 40s over the caviation plate in the Supreme Court -
http://caselaw.lp.findlaw.com/cgi-bin/g ... &invol=759Muncie later made I/Os rumor has it that the Muncie I/O became the Volvo - but I've never had that confirmed. However, MGW quit making I/O about the same time Volvo started making them...
There are many others - Champions, Neptunes, Lausons, and Rileys Riley was so cool - they made a 75HP, 4 cycle, 5 cylinder radial outboard in the 50s that was simply huge for it's time! Did ya get all that - 4 cycle? 5 cylinder radial? 75HP when everyone else was working at 35? Wow!
So it ain't no big news that OMC is running Zuki engines under their hood - it's a marine outboard tradition!
See ya on the water!!
