Common failures & inspection points
Inspect seawater intake for blockage, check raw water impeller wear, test thermostat operation, flush cooling passages; verify coolant level and antifreeze concentration every 250 hours
Drain fuel water separator regularly (recommended every 250-500 hours), inspect fuel filters for discoloration or debris, prime fuel system if air detected, replace fuel filters at recommended intervals
Visually inspect for oil weeping from cylinder head gaskets, oil pan, crankshaft seals; check engine oil level weekly; replace affected gaskets at service intervals (typically 500-1000 hours)
Inspect drive oil regularly for water contamination (milky appearance indicates water intrusion), change drive oil at recommended intervals, check seals and rubber boots for cracks or damage before each season
Inspect air cleaner for clogging and replace if restricted; check turbo boost pressure at full throttle (should be within specification); at 1000 hours, clean aftercooler core for carbon and salt buildup
