Systems

Chris-Craft 3–19

Do not start the engines without some type of cooling water circulat-

ing through the engine(s). Damage to the engine(s) will result.

To start the engines:

1. Ensure the fuel shut-off valve on the fuel tank is in the open position.

2. If necessary turn on the master battery circuit breaker and/or engage any other circuit breaker(s) that may be

required for engine start.

3. Ensure you have an adequate supply of cooling water circulating through the engine.

4. Ensure no one is around the propeller(s), and that they are free of obstacles.

5. Drop the sterndrive(s) into the water (if launching the boat).

6. Insert the clip(s) into the emergency shut-off switch(es) and attach the lanyard(s) to your person.

7. Place the throttles in NEUTRAL.

8. Activate the engine compartment blower and allow approximately four (4) minutes for the compartment to venti-

late.

9. Start the engine(s).

10. Gauge readings – Normal

Ensure someone is at the controls at all times. DO NOT leave the helm unattended with

the engine(s) running.

To stop the engine(s):

1. Turn the ignition switch(es) to OFF.

2. Turn off any circuit breakers necessary to prevent a restart.

3. If required, turn off the fuel shut-off valve on the fuel tank.

Do not approach the propeller(s) until the engine(s) have come to a complete stop and

there is no chance that the engine will restart.

Engine Throttles

There is one throttle for each engine (Figure 3-17). The throttle(s) controls the engine(s) speed which dic-

tates the speed of the boat through the water. The throttle combines direction and power in one unit. Mov-

ing the throttle forward increases the engine speed until full forward power is reached. Moving the throttle

aft puts the boat in reverse. Continued aft movement of the throttle increases engine speed until full power

is reached. The middle detent is the NEUTRAL position. The engines will not start unless the throttles are

in the NEUTRAL position.

Work with your dealer for instructions on the best way of handling throttle control.
