TMPEM07.4524

Inspect the engine compartment for fuel vapor, fuel or oil leakage, cooling-water leakage, exhaust leakage, poor ventilation, loose wiring, overheated terminals, and evidence of previous flooding or seawater exposure. Check raw-water and closed-circuit cooling components as fitted, including strainers, pumps, hoses, clamps, heat exchangers, thermostatic components, and accessible manifolds or passages for restriction, corrosion, scaling, leakage, and deteriorated rubber parts. Inspect ignition and fuel-system components, filters, hoses, electrical grounds, batteries, charging equipment, engine mounts, coupling or drive connections, and the exhaust system for deterioration or unauthorized modifications. Where a sterndrive or shaft arrangement is fitted, examine bellows, seals, bearings, alignment points, propeller condition, gear lubricant condition, and mounting hardware as applicable to the actual installation. During a running test, observe cold and warm starting, idle quality, charging voltage indication, cooling behavior, exhaust discharge, alarms, abnormal vibration or noise, shifting, and response under available load. Use the exact manufacturer documentation for service intervals, diagnostic specifications, fluid requirements, tightening values, alignment limits, and wear criteria.
