"That is a horse s--t idea. Now, if you took the engine or sterndrive and you stood it on end, and put it on top of the gear box, you'd have an outboard motor. Then you got the right touch!" Carl Kiekhaefer on the Stern drive 1951.

MerCruiser Company History
Aside from sailing and paddle boating, until the 1920's there were only 2 powered options to propel a boat through the water; the Outboard Motor and the Inboard Motor. Both of these power boat options however had their disadvantages. All Outboards including Mercury Outboards lacked in both horsepower and especially torque. In 1957 Kiekhaefer produced the most powerful Outboard motor in the world at just 60 Horsepower. However the Inboard motors having been converted from an automotive engine were both big & heavy. The other problem with Inboard Motors was that the engine required being angled such that a more optimal Propeller Shaft angle was achievable. This therefore meant the propeller angle was not just pushing the boat forward but also pushing upwards on the boat and not in the optimal direction the boat was traveling. In 1930 Johnson Motor Company released what was probably the first Sterndrive. However this product was plagued by lack of customer interest as well as lack of Boat Builder interest. Therefore the product basically dissolved in the wake of problems being pointed at the boat builder from the Sterndrive manufacturer and vice versa. At this point and up through March 23, 1961 when the Mercruiser product brand was initially launched, there lies a tremendous amount of controversy regarding the birth of the Mercruiser Sterndrive product line. Two engineers by the names of Jim Wynne and Charlie Strange are credited with the design concept of the Mercruiser Sterndrive as its known today. The biggest design enhancement to the earlier predecessors was the introduction of two 90 degree gears sets by use of universal joints. The controversy surrounding the history behind Mercury Engines and the Mercruiser product line comes from the fact that while Jim Wynne was credited with the "invention" of the Sterndrive after having left employment by Kiekhaefer in 1958, the truth was that the original design concept was that of Charlie Strang while still employed by and a very close friend of Kiekhefer yet working on the design and initial agreement with Volvo Penta. The irony in all of this is that Volvo Penta introduced the Sterndrive before Mercruiser however the design was developed by Mercruiser in a round about way.
Today, 50+ years later after the introduction of the Mercruiser Sterndrive, PPT allows you to use your Mercruiser Serial Number to find the correct Mercruiser Engine Parts for your Inboard or Sterndrive application. Having spent more than 25 years as mechanical engineers for Mercruiser while designing a variety of different Marine Exhaust & Marine Cooling Systems, this allowed us to develop a broad background in the Marine Industry.
