3. Use starting aids and crank the engine.As soon as the engine starts and runs, the lever will return to the RUN position. Jacket Water Heater (Attachment)
In very low temperatures, the lubricating oil must be warmed to allow starting. A jacket water heater maintains jacket water temperature at approximately 90°F (32°C). The warm jacket water will keep the oil in the upper part of the engine block warm enough to flow while starting.Dipstick Oil Heater
Contact your Caterpillar dealer before installing a dipstick crankcase oil heater.Engine Horsepower Ratings
There are two general horsepower ratings for marine engines and two for electric set engines. They are intermittent pleasure craft or continuous; and standby or prime, respectively. These ratings are the recommended engine horsepower settings which are based upon the load requirements and the type of engine operation.Continuous and Prime Ratings
Horsepower settings for these two ratings allow operating a constant load for long periods of time without shortening engine life.Intermittent Pleasure Craft Rating
Horsepower settings for this rating requires the engine to be operated for periods no longer than 5 minutes at full speed position followed by an equal time, or longer, of operation at reduced speed.
If an engine is set for an intermittent rating and is operated for longer periods of time at constant full engine speed, the engine life will be shortened.
Standby Rating
Horsepower settings for this rating allows the electric set to supply rated power for a period of time, after which the engine is stopped.Contact your Caterpillar dealer if there is doubt as to which rating your engine has.
Horsepower settings should only be done by authorized personnel.
Pre-Start Checks And Procedures
1. Make a "walk-around" check of the engine and components. Correct minor adjustments before they develop into major repair jobs.2. Check the crankcase oil level. The oil level must be between the ADD and FULL marks on the dipstick. See the LUBRICATION AND MAINTENANCE PROCEDURES.
CHECKING OIL ON 6 CYLINDER ENGINE
CHECKING OIL ON V-ENGINED379 and D398 Engines are equipped with a combination sump pump and prelube hand pump. After a prolonged shut down, or after a filter and oil change, operate the hand pump to fill the lube system oil passages before starting. See the LUBRICATION AND MAINTENANCE PROCEDURES for further details. 3. Check the marine gear oil level. Oil level must be at, or just slightly above the FULL mark with the engine stopped. Add oil as required. 4. Check the day fuel tank level. Keep the fuel tank full. 5. Check the engine jacket coolant level. The coolant level must be at the base of the fill pipe with the engine cold. 6. Open the sea water valve.7. Reset shutoff devices. See the topic ATTACHMENT, Emergency Shutoff Devices and Alarms.8. Open the fuel supply valve.
The fuel return line must be open to prevent engine damage.
9. If air has entered the fuel system, prime the fuel system. See the LUBRICATION AND MAINTENANCE PROCEDURES.
