Starting the Engine

TS220-UN-15APR13

Use Proper Ventilation

1. CAUTION: Before starting engine in a confined engine room, install proper outlet exhaust ventilation equipment. Always use safety approved fuel storage and piping.

   NOTE: If temperature is below 0°C (32°F), it may be necessary to use cold weather starting aids (See COLD WEATHER OPERATION, later in this section).

   Perform all prestarting checks outlined in Lubrication & Maintenance/Daily Section later in this manual.

2. Open the fuel supply shut-off valve.

3. If equipped, open fuel return shutoff valve. Verify that all fuel return lines are open and free of restrictions.

4. Set marine gear control lever in the “NEUTRAL” position on propulsion units.

5. Move the throttle control lever approximately 1/3 of the way off the idle position.

6. For Electronically Controlled Engines

   Turn the key switch to the ON position. The "Wait To Start Preheating" message will be displayed when ambient temperatures require preheating (for engines with preheating options). The timer will display minutes and seconds, counting down to zero. Once the timer has reach 0:00 and the "Wait to Start" message is no longer displayed, you may start the engine.

   For Mechanically Controlled Engines

   Turn the key switch to the ON position.

7. IMPORTANT: Do not operate the starter for more than 30 seconds at a time. To do so may overheat the starter. If the engine does not start the first time, wait at least 2 minutes before trying again. If engine does not start after four attempts, see Troubleshooting Section.

   If the start switch button is released before the engine starts, wait until the starter and the engine stop turning before trying again. This will prevent possible damage to the starter and/or flywheel.

   NOTE: Key switch (A) on main (standard) instrument panel must be in “ON” position to start engine using fly bridge (optional) instrument panel.

8. After the engine starts, observe the oil pressure gauge (C) until it reads at least the slow idle pressure specified for your engine in the Specifications Section.

9. For Mechanically Controlled Engines Only: Observe the “Low Voltage” warning light (D) immediately after engine starts, if light flashes on and off, stop engine and check V-belt tension and alternator output voltage.

10. Warm up the engine at or below 1200 rpm with no load for 1-2 minutes. See following guidelines.

11. Check all gauges for normal engine operation. If operation is not normal, stop the engine and determine the cause.

12. Check sea water outlet for water flow. Check exhaust pipe for water flow on engines with wet exhaust systems.

    If sea water does not flow within one minute after engine starts, stop engine and check sea cock, sea water strainer, and sea water pump for restrictions.
