1968 – THE BEGINNING OF OMC’s LEGENDARY LOOPERS
Billed as America’s first looped charged, multi-cylinder outboards - and the most potent motors in the mid-horsepower range - OMC’s revolutionary loopers produced more power per-cubic-inch with less fuel consumption. Over a 33-year period, the 2 & 3-cylinder loopers became two of OMC’s longest running and most profitable models.
A Wide Range of Models – From Pleasure Boats, to Racing, to Military, to Commercial - The 55hp 3-cylinder was launched in 1968. In 1971, a 2-cylinder, 50hp looper joined the 3-cylinder looper which had increased to 60hp in 1970. Continuing power increases for the 3-cylinder model followed with 65hp in 1972, then 70 hp in 1974. Also in 1974, both brands targeted performance boating with specially styled and named loopers – the 70hp Evinrude Hustler and Johnson Stinger. (The Stinger is best remembered for its striking orange paint job.) Evinrude extended their performance offerings with a 2-cylinder 50hp Sizzler. Looped horsepower jumped again in 1976 when Evinrude introduced the 75-S and 55-S Sport models and Johnson debuted the 75hp Stinger and a 55hp 2-cylinder. While the 3-cylinder motors peaked at 75hp, the 2-cylinder line-up would expand to 50, 55 & 60 horsepower models by 1980. (See the ads for additional tech info.)
THE “RED HOT” STINGER– Launched as a “1972 Limited Edition” model - just in case screaming orange was too daring - the 65hp Stinger was an instant hit. The 1972 / 1973 model, shared identical mechanicals with the standard 49.7 cu. in. Johnson 65 looper producing its BIA certified horsepower at 5000 rpm.
Playing off that initial success, an upgraded 70hp Stinger followed in 1974 with a massive ‘70’ on its flanks. Its additional 5 horses were credited to refined tuning and improved carburetion. Doubling down on performance, horsepower increased again in 1975, now to 75. Again, festooned with a bold horsepower ID on its sides announcing its presence. Those extra 5 horses came from new exhaust ports, a redesigned combustion chamber and a new, low restriction air-intake silencer with a BIA certified 75hp rating at 5500 rpm. A high-compression cylinder head was optional.
RACING LOOPERS – The Evinrude CC & Johnson SR were 49.7-cubic inch, triple cylinder race engines based on the 75-hp Johnson Stinger & Evinrude Hustler block. These racing loopers are likely best remembered as pure factory-available, race-ready outboards. Both the 2 & 3-cylinder loopers competed in various stock production classes and race-tuned classes over the years, winning consistently. In addition, stock production motors with 15-inch lower units and high-speed Nitro gear cases also took top honors.
MILITARY LOOPER - The 2002 US Navy Seal Enforcer 2-cylinder, 55hp submersible outboard. Designed specifically for beach landings and to be submersible with a de-watering system that could drain water from the engine, should it be intentionally or accidentally submerged. The outboard lower unit was an enclosed pump-jet system preferred by Special Forces to avoid inadvertent injury to divers in the water.
COMMERCIAL LOOPERS – Starting with the 2-cylinder, 50hp, rope start, tiller model in 1979, these motors became highly regarded as tough and reliable working outboards around the globe, usually in remote rural locations. Over the years, 55hp, 60hp & 65hp models were added. Commercial loopers were detuned versions of the standard motors to utilize low octane, poor quality, fuel often found in 3rd world countries. They had extensive anti-corrosion coating in critical areas and more stainless steel fasteners than the regular production engines. The water pumps used a chrome-plated aluminum pump housing for longer life in muddy or sandy waters.
Notably, Johnson commercial outboards were dominant in several countries including South and Central America. In many places there, an outboard was referred to as a “Johnson” – no matter the actual brand. In fact, someone who ran an outboard was known as a “Johnson operator.”

Johnson Stinger - THE MEAN MACHINE
The first ‘hot orange’ Stinger 65 was introduced in 1972 on NBC’s splashy national TV special “Discover Wet” hosted by Johnny Carson’s sidekick Ed McMahon at Cypress Gardens. By the early 1970’s, Johnson styling had become a bit conservative - and certainly not flashy!, So the introduction of a screaming orange outboard was quite jarring...if not daring from a marketing standpoint. Launched as a “1972 Limited Edition” model - just in case screaming orange was “too daring” - the 65hp Stinger was an instant hit. The 1972 / 1973 model, shared identical mechanicals with the standard 49.7 cu. in. Johnson 65 looper producing its BIA certified horsepower at 5000 rpm.
Playing off that initial success, an upgraded 70hp Stinger followed in 1974 with a massive ‘70’ horsepower ID on its flanks. Its additional 5 horses were credited to refined tuning and improved carburetion. Doubling down on performance, horsepower increased again in 1975, now to 75. Again, festooned with a bold horsepower ID on its sides announcing its presence. Those extra 5 horses came from new exhaust ports, a redesigned combustion chamber and a new, low restriction air-intake silencer with a BIA certified 75hp rating at 5500 rpm. A high-compression cylinder head was optional.

Evinrude Powered FIERO BOATCAR
Powered by an Evinrude 50hp looper outboard, this “boatcar” is likely better as a boat than it was as a car. Those who remember this little mid-engine Pontiac will recall that the 1984 introduction year cars had a propensity to catch fire. By mid-1987, the 1984 Fieros were catching fire at a rate of about 20 per month. Its Iron Duke engine dated back to 1977 and wouldn't fit as it was, so a redesigned sump and oil pan were used but the dipstick wasn't changed so the oil level would appear to be normal when it was in fact a quart low. Now add to this, defective connecting rods that only exacerbated low engine oil levels, and fires would result. In addition, a wiring harness mounted just above the exhaust manifold was also given to melting and starting electrical fires, and improperly-tightened head bolts would also sometimes crack the block and start a fire.(The Iron Duke engine has been removed from the boatcar.)

My brother Lennart Ström raced/tested the first new F3 engine in Martinique late 1987/early 1988. There was some issues OMC corrected and this is/was an extremely good engine used in UIM F3 racing for many years.

Lennart Strom ruled the UIM F3/OE class in the middle/late eighties.
https://svera.se/blogg/lennart-strom...late-eighties/
Yes, Lennart was ready for the UIM F1-2 liter class late 1990.
Our team purchased a new 2 liter Burgess boat (#21 below) and a new 2 liter UIM F1 engine from Mercury Racing.
This is from late 1990 in Chalon, France.
Lennart blow the brand new Merc V6 engine in testing..Mercury refused the help him out.. We were forced the purchase a new powerhead and Lennart blow a piston in the race.
This was a terrible time for the 2 liter V6 Merc UIM F1 engine.
1991 Lennart purchased 11 sets of pistons from Mercury and 3 blocks..He could never finish a race because engine trouble.
If I remember correct Mercury figured out the piston issues 1992-93 but Lennart was so disappointed and his full time racing was on hold.

The top teams in Mercury 2L Champ racing were lucky to get one race out of a single set of pistons. They were rebuilding every engine they had between races. Mercury also had lower unit gear hardness problems. They either held up or turned to butter. OMC USA F1 tour had a clever trick with fuel. All teams HAD to use their fuel (which was provided at cost). They octane rating was just a little bit off from spec but the V8s would run all day on the stuff. The Mercury 2L guys who entered the V8 events` were frying their Mercs trying to keep up. One Merc entrant accused me of forgetting to add 2 stroke oil to his fuel mix!
