Safety is basically common sense. A general guide of safety precautions may be listed, but each installation has its own peculiarities which cannot always be predicted and covered by rules. Past experience and common sense are needed for the necessary safety measures. Lack of attention to safety can result in serious accidents. Be alert. Watch for hazards. Use preventive measures. Correct deficiencies promptly.Safety is EVERYONE'S Business!!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 engine crankcase oil level. The oil level must be between the ADD and the FULL marks on the dipstick.3. The marine transmission oil level should have been checked before stopping the engine (see OPERATING PROCEDURES, Stopping). If the transmission oil was drained since stopping, be sure the proper refill quantity of oil has been added. 4. Open the sea water valve.5. After the engine starts, check the marine transmission oil level at low idle with the marine transmission engaged. Maintain oil level between the ADD and FULL marks on the dipstick. See the LUBRICATION AND MAINTENANCE PROCEDURES.6. At frequent intervals the gauges should be observed. Determine the normal reading for each gauge. Investigate the cause whenever there is a significant change in the reading.Periodic monitoring and recording of the gauge readings will provide a performance history of the engine and marine transmission. As certain conditions develop, a change in a reading will indicate a problem is developing. The necessary repairs can be scheduled before the failure and unexpected downtime occurs.Operating Engine And Marine Transmission

Marine Transmission Oil Temperature
The marine transmission oil temperature depends upon the temperature and the quantity of sea water pumped through the marine transmission oil cooler. The normal marine transmission oil temperature range is 150°F to 175°F (66°C to 79°C).If the oil temperature is above the normal operating range: 1. Determine if the high temperature could be caused by severe operation: long periods of trolling, or numerous changes in direction of travel.2. Check the temperature of the sea water: Determine if the water passing
