What is a Marine Engine Survey?
805 Marine Mechanic uses TEXA Dealer Level Marine Diagnostic Tool for ECM (Electronic control module) computerized Diagnostic engine survey software covers most inboard marine engines including. Caterpillar, Cummins, MAN, Volvo Penta, MTU, Scania, Perkins, Universal, FPT, John Deere, Ford Marine, Detroit Diesel and more.
A term used to describe an engine condition assessment (evaluation) in the marine industry. As with other types of marine survey, ‘engine surveys’ are usually performed during boat or ship sales and may be required periodically for insurance purposes.
External visual inspection of the engine coupled with extensive computerized dealer level diagnostic testing on engines with ECM (Electronic control module) hook up. supplied on most engine models 2000 and newer.
Upon request, a compression tests, borescope test, can be provided at an additional charge. Following our diagnostics, we provide you with a detailed written report of our findings.
explaining any issues we’ve discovered, and the steps needed to optimize your engine’s performance. oil analysis included in diagnostic service.
What testing is included in a Marine Engine Survey / Sea Trial.
ECM Hook up: connection of computerized diagnostic port. were applicable.
Cooling System Pressure Test: Pressure testing the cooling system of a boat is essential to identify leaks and ensure proper functioning.
Cold Engine Starting:
WOT (wide open throttle): usually between 5 – 10 minutes. nearly every marine diesel engine manufacturer warrants their engines ability to operate at full throttle for 10 minutes. M rating M1 – M5
Instrument and warning light alarm functionality:
Engine vibration: observed throughout its operating range.
Exhaust manifold temperature:
Engine Oil temperature: before and after the lube oil cooler.
Transmission Oil Temperature: before and after the transmission oil cooler.
Fuel oil temperature: before and after the fuel oil cooler.
Coolant temperature: before & after the heat exchanger.
Pressure to seawater inlet restriction or vacuum:
Engine oil pressure:
Transmission oil pressure:
Fuel oil & turbo boost pressure: ECM equipped.
Exhaust gas temperature: ECM equipped.
Shaft log temperature:
Hoses & Clamps: checked for abrasion, cracking, kinking, deformation, and fitting.
Belts and (external) chains: checked for wear, cracking, tension, and flexibility.
Electrical wires: cables, and connections examined for corrosion and mechanical wear.
Noise or vibration while shifting in & out of gear:
Inspection of engine mounts:
Oil Analysis: We draw samples of engine and crankcase oil for laboratory analysis. The results of this analysis can alert you to a variety of issues ranging from worn out bearing to leaking head gaskets.
Coolant Analysis: Transmission oil analysis:
if requested at additional cost of $75.00 per test.
Formal surveys end with a written report, which describes the engine’s general condition, along with any specific problems that the surveyor identified, and what service should be performed on the engine in the near term. Some surveys may estimate the engine’s value and/or how much the service/repairs are likely to cost.

FINDINGS:
Caterpillar C12.9 marine engines, port & starboard. ran very smooth & sounded strong, low hours, did not observe any black smoke or smoke of any kind that would lead me to believe that they had much wear. Port Generator Onan 21.5…. TRACE LEVELS OF WATER DETECTED (0.1%) MAY BE CONDENSATION. ALL OTHER ANALYSIS READINGS APPEAR NORMAL. I SUGGEST CHANGING THE OIL & FILTER. RUN IT FOR 10 HOURS AND THEN RESAMPLE THE OIL.
MARINE ENGINE SURVEY SUMMARY:
As a result of my investigation, MARINE ENGINE SURVEY, and by virtue of my experience, my opinion is OVERALL ENGINE RATING: VERY GOOD: the engine room and engines appear to be extremely well maintained. the entire space was free of oil and grease & spotless,
