ENGINE:

 

Engine Room Systems:

THROTTLE & SHIFTER CONTROLS: Morse cable shifters worked properly.

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.

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

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

SEAWATER STRAINER: 1 1/2 Groco bronze alloy with sight glass. Appeared serviceable. well maintained

COOLANT LEVEL: Normal levels observed. Pressurized expansion tanks on engine 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.

BELTS AND PULLEYS: Tensioner arm, idler pully and serpentine belt seem to be worn out. should replace in the near future.

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, 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 

ENGINE ALIGNMENT: Appeared Smooth & without vibration.

RUDDER: outside hull style, appeared serviceable. no vibration.

TURBOCHARGER: no boost tests performed on turbo, sounded like it spooled up around 1200 RPM and operated satisfactory

SEATRIAL REPORT:

1. The engine started without excessive cranking.

2. The engine exhaust appeared normal.

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 throttle operated normally. no adjustment needed

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

8. The backdown test was satisfactory.

9. rudder linkage operated smooth while underway.

WOT TEST: (wide open throttle) operated for 3minutes, no smoke no overheating of any
kind observed with heat gun and gauges, no strange noises from engine or transmission,
Engine transitioned extremely smooth from idle to WOT.

 

Recommendations and observations:

  1. Tensioner arm, idler pully and serpentine belt seem to be worn out. should replace in the near future.
  2. the engine was Refurbished by Cummins around 2018. and with such a low number of hours it seems to be in great shape, there was 0% of oil or other liquids in the bilge after the Sea trial. and the engine didn’t smoke at all except for a little bit at start up until it warmed up, (normal operation, especially for Cummins) even when we went from idle to WOT, no smoke which is rare. overall, a big 2 thumbs up.
