C8.3 Commercial Marine and Ind [...] Normal Starting Procedure Section 1 - Operating Instructions Page 1-5 To reduce the possibility of damage to the starting motor, do not engage the starting motor for more than 30 seconds. Wait 2 minutes between each attempt to start (electrical starting motors only). NOTE: Engines equipped with air starting motors require a minimum of 480 kPa [70 psi]. CAUTION Disengage the driven unit, or if equipped, put the transmission in neutral. With the accelerator pedal or lever in the idle position, turn the key switch to the ON position, and wait for the WAIT-TO-START lamp to go out; then, turn the key to the START position.
Full throttle is applied after engaging the starter, after 5 seconds release to idle throttle. If the engine does not start after three attempts, check the fuel supply system. Absence of blue or white exhaust smoke during cranking indicates no fuel is being delivered.
