Full list of Mercury Mercruiser engines covered in this manual is below:

Mercury MerCruiser offers a range of gasoline engines with both angled tilt speakers (Sterndrives) and reverse gearboxes (Inboards) with high performance from 135 to 425 hp.


All carburetor engines for convenience are equipped with an exclusive launch system TKS. You do not need any suction, no swap, no pre-fill fuel. Just turn the key in the ignition and the engine is running. All engines with a multipoint fuel injection system (MPI) are equipped with an ECM 555 electronic control unit developed by Motorola. Engines with multipoint fuel injection are equipped with SmartCraft measurement and control system, which provides control of engine operating conditions and onboard equipment of the vessel.

MerCruiser together with Cummins produces diesel engines under the Cummins MerCruiser Diesel (CMD) brand. Diesel engines can also be used with turntables (Sterndrives), as well as in the tails (Inboards).


The company produces the widest range of tilt-and-turn speakers in the industry, with models designed for all kinds of boats, from sports to pleasure and racing. Whether it is the Alpha and Bravo robust speakers with smooth, noiseless gear shifting, the long-life Bravo X speakers are all designed and manufactured in the process of tireless and responsible work to ensure high performance and long-term engine life.


Using advanced technologies that exceed all expectations for reliability and performance, Mercury MerCruiser stationary engines have every chance in the future to maintain leadership in the field of propulsion systems for water equipment.

    Hi: I'm looking for a downloadable manual for the 1988 OMC Drive System Model 432APRGDP. There's an old manual in the boat, badly mold-damaged. All I can read off it is:
    OMC Stern Drives SP/SX/SX Cobra, Cobra King, Cobra & DP/DP Duo Prop 1986-93

    Thanks in advance!
