This manual covered Include V-8 GM; V-8 ; In-line GM/60/80/90; MerCruiser 60/80/90; I; II Early; II Transom; III; 215H; 215E; II-TR Drive Unit.


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 there,

    I have a problem on my Mercury 2003 40 HP elpto ot638252. I had a new floor put in my pontoon and I think there is a problem with the throttle linkage. Since they had to remove all the wiring and linkage to put in the new floor. I think maybe the problem is with the linkage not moving centering into neutral. My motor will not start and I think it has to do with a clip that may have fallen off the throttle linkage on the control handle or the motor itself. . I have the clip but I don't know whether it goes on the linkage in the motor or if it is supposed to go on the speed control handle control. If you could lead me in the right direction that would be much appreciated. I can send a pic of the clip and the instructions attached to it.
