Shifting
(1) FORWARD (2) NEUTRAL (3) REVERSEThis transmission has one forward and one reverse speed. See above.For best performance and maximum service life, shifting of the transmission must be done in a specific manner.Listed below are the transmission manufacturer's recommendations: Starting the Load
Proper operation and maintenance are key factors in obtaining the maximum life and economy of Caterpillar marine engines. Following the directions in this guide will help reduce operating costs.After the engine starts and normal oil pressure is reached, operate the engine at low load until the temperature gauge reaches operating temperature, before operating at full load.Engage the marine gear by moving the control lever in the desired direction. Allow one second before increasing engine speed.
Do not shift across neutral position without a few seconds delay.
When reversing the direction of propeller rotation, reduce engine speed to low idle. Place the gear control lever in neutral position. Hesitate two seconds, then move the control lever to the new position. Allow one second for the clutch to become fully engaged before increasing engine speed. The marine gear rotation should not be changed at full engine speed.Cruising Speed
To establish proper cruise speed for any existing condition of a vessel, perform the following:1. Run the vessel under way at maximum speed for about four minutes.2. Take the tachometer reading. This is the maximum engine speed for the present conditions of the vessel.3. Reduce the engine speed until the tachometer reading is 300 to 400 rpm less than the maximum tachometer reading observed in step 2. The engine is now operating at recommended cruising speed.Operating at the recommended engine cruising speed will give maximum engine service life and most economical operation.Pleasure Craft
This rating is to be used in recreational vessels only. Full power operation is limited to five minutes duration followed by extended periods of operation at continuous power levels and below. If the annual hours of operation are 200 hours or less, the load factor is 20% and less.Light Duty Commercial
This rating is for light duty commercial service where the load and speed are cyclical. Full power operation is limited to one hour duration followed by extended periods of operation at continuous power levels and below. If the annual hours of operation are 1500-2000 hours, the load factor is 30% and less.Medium Duty Commercial
This rating is for use in commercial service where the engine load and speed are essentailly constant with some cycling. Up to four hours of full power operation in any one work interval is possible. If the annual hours of operation are 4000 hours or more, the load factor is 90% and higher.This rating is also to be used within certain national agency and Marine Classification Society Requirements where an overload rating is necessary in terms of establishing a normal continuous rating. When the rating is required to be stated it will be called "Maximum Continuous" and is to be regarded as synonomous with "Medium Duty Commercial."Continuous
This rating is for heavy duty commercial service where the engine is operated
