FUEL FILTRATION SYSTEM: Racor Twin Turbine Series Fuel Filter/Water Seperator 10 Micron Port & Starboard side filter assembly: Appeared serviceable, No water present. Electric priming pump & vacuum gauges installed. FUEL POLISHING SYSTEM also installed no water present appeared serviceable

THROTTLE & SHIFTER CONTROLS: Morse cable shifters worked properly at flybridge and Main cabin locations.

SEAWATER PUMP: Seals not leaking/no water present. adequate pressure.

TUBE-TYPE HEAT EXCHANGER: checked inlet and outlet flow temperature, within parameters

ENGINE OIL COOLER: checked inlet and outlet temperatures, all within parameters

SEAWATER PUMP OUTLET PRESSURE: adequate pressure

COOLANT LEVEL SENSOR: working properly no leaks observed.

ENGINE MOUNTS AND BED:  Main engine beds are heavy longitudinal stringers inboard and outboard. Engine Mounts Satisfactory

LUBRICATION: Oil Level indication is normal both port and starboard.

LUBE OIL PRESSURE: (WOT) engine 100% load 51 psi. port engine 50 psi starboard engine

COOLING SYSTEM TYPE: Freshwater reservoir type cooling with Seawater cooled wet exhaust, Operated satisfactory.

SEAWATER STRAINERS: 3 inch Groco bronze alloy with sight glass. Appeared serviceable. well maintained

COOLANT LEVEL: Normal levels observed. Pressurized expansion tanks on both engines to 25psi no noticeable drop in pressure. used heat sensing gun on all cooling system surfaces. operated normal.

HOSES AND CLAMPS: Double clamped where sighted. Hose Clamps on both engines saltwater system should be replaced at next service

BELTS AND PULLEYS: Belts & Pulleys condition appeared serviceable

SEACOCKS AND STRAINERS: Seawater seacocks were ball valve type. Operated smooth & satisfactory. 

EXHAUST SYSTEM: Seawater cooled with risers and flexible coupling sections double clamped where sighted. 

ENGINE ALARMS: Test of port and starboard low oil pressure alarm, and coolant overheat warning audible at helm station. Operated satisfactory.

ENGINE SHUT DOWN: electronic style shut off solenoid switches operated satisfactory 

DRIPLESS SHAFT SEALS: seem to have adequate pressure no leaks observed.

ENGINE ALIGNMENT: Appeared Smooth & without vibration.

RUDDERS: Packing gland style, not leaking excessively appeared serviceable. no vibration.

TURBOCHARGERS: no tests performed on turbos, sounded like they spooled up around 1200 RPM and operated satisfactory

ZF MARINE TRANSMISSIONS: Both performed adequately while shifting no excessive noise or vibration while under way. 

——————————————————————————————-

SEATRIAL REPORT:

1. The engines started without excessive cranking.

2. The engine exhaust appeared normal. very minimal smoke for engines of this age.

3. The cooling water exhaust appeared adequate and normal.

4. The engine instruments operate within normal operating limits at idle, cruising speed and at wide open throttle.

5. The steering system operated normally. very responsive.

6. The throttles operated normally. no adjustment needed

7. The transmissions, both went in & out of gear smooth with no excessive noise

8. The backdown test was satisfactory.

9. both rudder linkage operated smooth while underway, no leaks detected

WOT TEST: (wide open throttle) Starboard engine smoking a little. but it seems to go
away as soon as the engine is warmed up.

 

ENGINE OIL ANALYSIS:

CLEONE-STARBOARD-ENGINE

CLEONE-PORT-ENGINE

 

CUMMINS QMS11 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:  GOOD: the engine room and engines appear to be well maintained. 

 

 

Engine Room Clean and Tidy, very well maintained.

 

Fuel Polishing System

 

Both Transmissions operated extremely smooth, no leaking at either dripless shaft seals

• They verify compliance with insurance standards.
• They furnish certified reports for buyer confidence.
• They benchmark engine condition to support higher resale offers.

 

Marine surveys are crucial for both boat owners and insurers, facilitating accurate risk assessment, ensuring compliance with safety standards, providing accurate asset valuation, and preventing fraud. These surveys are often a prerequisite for obtaining insurance coverage and help determine appropriate premiums and coverage limits.

This information directly supports the article’s claims regarding the importance of specialized surveys for investment protection, insurance compliance, and enhanced resale appeal.

 

Efficient oil purification and filtration are critical for maintaining optimal performance, preventing damage, and extending the lifespan of marine diesel engines. Contaminants in lubricants can lead to increased wear and reduced efficiency, highlighting the importance of methods like sedimentation, filtration, and centrifugation for effective oil purification.

This research supports the article’s emphasis on fluid analysis for revealing internal component wear rates and informing targeted maintenance, contributing to engine longevity.

1. Execute wide-open-throttle runs to assess power delivery.
2. Monitor temperature and pressure gauges under load.
3. Observe throttle response and exhaust coloration.

• Fuel-filter clogging from microbial growth
• Coolant-system corrosion and leaks
• Bearing wear in high-speed rotating parts
• Exhaust soot buildup affecting performance
