Stop the engine and allow the oil to drain back into the sump for a minimum of ten minutes.
Check the crankcase oil level. Maintain the oil level between the "ADD" mark and the "FULL" mark on the oil level gauge.
If necessary, repair any leaks.
If necessary, perform minor adjustments or tighten loose bolts.
Note the service hour meter reading. Perform the maintenance that is in the Operation and Maintenance Manual.
Fill the fuel tank in order to help prevent accumulation of moisture in the fuel. Do not overfill the fuel tank.
Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.
Only use antifreeze/coolant mixtures recommended in the Refill Capacities and Recommendations topic that is in this Operation and Maintenance Manual. Failure to do so can cause engine damage.
Allow the engine to cool. Check the coolant level. Maintain the cooling system at 13 mm (0.5 inch) from the bottom of the pipe for filling. The cooling system can also be maintained between the "COLD FULL" mark and the "LOW ADD" mark on the coolant recovery bottle (if equipped).
If freezing temperatures are expected, check the coolant for proper antifreeze protection. The cooling system must be protected against freezing to the lowest expected outside temperature. Add the proper coolant/water mixture, if necessary.
If freezing temperatures are expected, drain the keel cooling system (if equipped).
Perform all required periodic maintenance on all driven equipment. This maintenance is outlined in the instructions from the OEM.
