In 1928, Ole Evinrude helped start OMC (Outboard Marine Corporation). The company manufactured outboard boat motors under the OMC-Evinrude name until being purchased by Bombardier Recreational Products. Although Bombardier has dropped the OMC name, the company continues to produce a line of outboard motors under the Evinrude nameplate. These motors each have a Three-Star rating in the California Air Resources Board emissions standards rating system, are compliant with U.S. EPA and European Union emissions standards, and offer a three-year non-declining warranty.

Inline

The Evinrude inline series of motors include 25- and 30-horsepower models designed with an inline two-cylinder engine. These motors offer a full throttle range from 5,500 to 6,100 rpm. Bore and stroke measurements are 2.99 by 2.5 inches with alternator output of 56 amps. Total engine displacement is 35.2 cubic inches. These 25- and 30-horsepower units offer the choice of a 15-inch or 20-inch shaft length with a gear ratio of 2.15-to-1. Starting options include rope, or a rope and electric combination. The trim may be adjusted by power, or manually, depending on the specific model. Steering is achieved using the tiller or can be done remotely.

The V-4 line of outboards offer engine models that get 115 and 130 horsepower at 5,750 rpm, each with remote steering and powered trim adjustment. These motors have electronic start and shaft length of either 20 or 25 inches. Models with 20-inch shafts have a 2.0-1 gear ratio, while 25-inch units have a ratio of 2.25-to-1. Both engines in this line are the Evinrude V-4 60-degree E-Tec DI design with a displacement of 105.4 cubic inches. The bore and stroke of both motors is 3.60 by 2.58 inches. Full throttle rpm range is 5,500 to 6,000. These outboards have 133 amps of total electrical output.

Evinrude's V-6 outboard motors range from 150 to 300 horsepower. The models that produce 150horsepower at 5,850 rpm are designed with the V-6 60-degree E-Tec DI design, offering 158.2-cubic-inch displacement. The bore and stroke on these models is 3.60 by 2.588 inches with a full throttle range between 4,850 and 5,850 rpm. Electrical output is 133 amps. The 150-horsepower models have a 15- or 20-inch shaft with an optional 1.85-1 or 1.86-1 gear ratio. Each 225- to 300-horsepower motor offers a 20-, 25- or 30-inch shaft with a 1.85-1 gear ratio. Both are the V-6 90-degree E-Tec DI type engines. The units with 225 horsepower at 5,150 rpm have 200-cubic-inch displacement with bore and stroke of 3.85 by 2.85 inches. Full throttle range is 4,500 to 5,800 rpm. The engine with 300 horsepower at 5,500 rpm has 210 cubic inches of displacement with a bore and stroke measurement of 3.8 by 3 inches. This motor's full throttle range is 5,000 to 6,000 rpm. The 225- and 300-horsepower engines have 133 amps of electric output. In addition, each V-6 model has electric start and remote steering with power trim and tilt adjustment.
