Evinrude 150HP V6 FI Oil Inj ETEC 2012 Calif EmisPower head

Evinrude 150 HP ETEC FI Oil Inj 2012 California Emissions complete Power head. V6 2 stroke. Ran when leg was parted out. Price is firm. All connections to the engine enter on the right side. The electrical connections are all made under the shroud seen here in the center. The E-TEC fuel injectors are mounted on the top of each cylinder. The injector housing is an alloy casting. Fuel Rails Fuel is distributed to the injectors by flexible rubber lines. There are both supply and return rails. The fuel pressure in the lines is not especially high, so rubber hose can be used. The same injectors are used in all E-TEC engines. Engine Management Module The operation of the engine is controlled by the Engine Management Module (EMM). The firmware in this computer system can self-power and be ready to operate after one revolution of the crankshaft. That is a "fast boot" processor! There are four LED diagnostic indicators that indicate status in either start or run mode. Even without an electronic diagnostic tool connected, you can get important engine information from the four indicators. Water flow is controlled by the thermostat at the top of the cylinder head. Fuel from the injector rails is returned to the fuel vapor separator/cooler. Note the easy access to the spark plugs; there is nothing in the way to complicate removal. On the smaller models, the spark coil is directly mounted to the E-TEC injector on the stand-off pillars molded into the injector. Here, those pillars are not used, and the spark coils are mounted close-by. High tension leads with nylon mesh covers connect the spark plugs to their individual coils. The starter motor is on the left side. The fuel pump feeds a filter, which in turn feeds the cooler/vapor-separator. Fuel is distributed to the injectors, and unused fuel returned to the cooler. Cooling water is circulated through the cooler/vapor-separator to keep the fuel temperature low, as the fuel tends to accumulate heat from cycling through the injectors.
