The 3412E marine engine is a 65 degree V-12 arrangement. This engine has a bore of 137.2 mm (5.40 inch). The engine has a stroke of 152.4 mm (6.00 inch). The bore and the stroke provide a total displacement of 27.0 L (1648 in3).
The hydraulic electronic unit injector fuel system (HEUI) eliminates many of the mechanical components that are used in a pump-and-line system. The electronic control and hydraulic actuation also provide increased control of the timing and increased control of the fuel injection pressure. The timing advance is achieved by precise control of the unit injector timing. Engine speed is controlled by adjusting the injection duration. A special speed-timing wheel provides information to the Electronic Control Module (ECM) for detection of cylinder position and engine speed.
The engine has built-in diagnostics in order to ensure that all of the components are operating properly. In the event of a system component failure, the operator will be alerted to the condition via the diagnostic lamp that is located on the control panel. An electronic service tool can be used to read the numerical code of the faulty component or condition. Intermittent faults are also logged and stored in memory.
Starting The Engine
The engine's ECM will automatically provide the correct amount of fuel in order to start the engine. Do not hold the throttle down while the engine is cranking. If the engine fails to start in twenty seconds, release the starting switch. Allow the starting motor to cool for two minutes before using the starting motor again.
