Introduced for the 1986 model year was the Cobra. OMC built an all-new, modern sterndrive factory in Lexington, Tennessee and started producing a traditional style sterndrive. Drawing heavily on the Mercruiser and Volvo sterndrive designs, the new Cobra had a transom mounted drive utilizing U-joints and trim rams. The engine was mounted solidly to the stringers in front and to a transom mounted plate in the rear. To entice the boat manufacturers who had installed only Mercruiser drives in the past, the OMC Cobra was designed to fit in the same size cut-out hole (in the transom) as the Mercruiser. This way a boat could be manufactured, the transom hole cut, and either the Mercruiser or the Cobra sterndrive package could be installed per market demand. Rigging the boat with a Cobra sterndrive was as easy as rigging with a Mercruiser sterndrive. Even the steering cables could be interchanged! here
The OMC stern drive was produced by the Outboard Marine Corporation from 1962 until the end of 1992. Because the 1962 and 1963 models used only an 80 horsepower V4 outboard powerhead, for all practical purposes it could be said that the first modern OMC sterndrive was not made until 1964 when it became available with the 110 horsepower 153 cubic inch inline 4 cylinder Chevy II automotive engine.
Another unusual aspect of the OMC stringer is the method used to trim the drive while operating the boat. Utilizing U-joints, the Mercruiser and Volvo drives can be tilted/trimmed separately from the engine. This tilt/trim adjustment is made with hydraulic trim rams. The OMC ball gear system doesn’t allow the drive to be tilted/trimmed separately from the engine. The complete engine and drive assembly must be rocked back and forth within the boat to trim the drive and propeller. The front of the engine is lifted or lowered to change the propellers angle of attack.
By the early 1980’s the writing was on the wall, the technology that OMC chose for the sterndrive was running down an evolutionary dead end. All modern sterndrives would have U-joints, transom mounted engines and drives, mechanical shifting and trim rams more
Both the 400 and 800 series gearcases evolved from the Johnson/Evinrude outboard line (a division of OMC). The 4-cylinder/400 gearcase is similar to the V4 outboard gearcase and the V6/V8/800 series gearcase is similar to the V6 outboard gearcase. Other than the addition of a water pump, different drive shaft and shift mechanisms the stringer and Cobra gearcases will interchange with some of the outboard gearcases! here
The only pieces to survive the OMC redesign from the stringer to the Cobra were the 400 and 800 lower gearcases. Other than minor differences in the shift mechanism, the stringer lower gearcases and the Cobra lower gearcases are virtually identical with many interchangeable parts, including the housing itself!
