Corrections to the Programmable System Parameters
The , "Ether Control" information that is on Page 31 is not correct. The correct information follows.
Ether Control
Note: This is an optional feature.
The ECM automatically injects ether into the air inlet manifold when the following conditions are met:
- The engine rpm is greater than 75 rpm.
- The temperature of the jacket water is below 31 °C (88 °F).
The duration of ether injection varies linearly with the temperature of the jacket water. The duration of ether injection varies within the following range:
- 10 seconds at the maximum temperature of 30 °C (86 °F)
- 130 seconds at the minimum temperature of -40 °C (-40 °F)
The longest duration of ether injection is 130 seconds even if the temperature of the jacket water is less than -40 °C (-40 °F). See Illustration 1.

A switch is installed on the control panel or the instrument panel. The switch enables the operator to inject ether manually under the following conditions:
- The switch for ether injection is in the manual position.
- The engine rpm is greater than 75 rpm.
- The temperature of the jacket water is less than 31 °C (88 °F).
Correction to the Maintenance Interval Schedule
The second Top End Overhaul that is identified on Page 92 is not correct. NO second Top End Overhaul should be scheduled. The Major Overhaul should occur between 18,000 and 22,000 Service Hours.
