Standard: No leaks in lube oil, fuel oil, water and exhaust systems. Engine oil pressure should be 20 psi at idle,
45-70 psi at full speed. Water temperature should not exceed 195F at full speed. Reduction gear oil pressure
should be 250 psi when gear is warmed up. Engine responds smoothly to controls from all stations without
surging or hesitation. Engine and drive train do not vibrate excessively. Shaft brake engages within 7 seconds
when engine is shifted into stop and releases immediately when engine is shifted to ahead or astern operation.
