روش اجرایی بازرسی موتور کشتی

Engine beds

.Check for cracks, water/oil mixture, and puddles of water or moisture

Engine motor mounts

Examine the mounts for cracks, misalignment, and distortions

Engine coupling shaft

Are these properly aligned? Check that they are bolted properly and the fasteners are in good condition

Hoses

.These should be soft and free of wear and cracks
.

Wiring

Electrical connections at the engine and batteries should be insulated. Look out for electrical tapes and naked wires

Engine Belts

.Depress each engine belt gently with your thumb. If the depression is over 1/4″, there is a problem

Gaskets and Seals

Inspect the block, manifold, and oil pan for leaks and heat spots as they indicate overheating
.Examine seals on the injectors, fuel lines, and lift pumps
?Check for leaks around the fuel tanks and fuel filters. What does the place smell like? Diesel, damp or oil

Check the Dipsticks

Read the dipsticks of the oil sump and transmission gearbox
.
Check the color and reading in the second sounding. If the lubricant smells burned or appears milky or bubbly, the engine block might be cracked

Check the Impeller Housing

Examine the impeller vanes for wear and distortion
.

Inspect for Zinc anodes

Inspect the zinc anodes on the propeller shaft or hull, as well as in the engine heat exchange if they are used
A fully compromised shaft zinc can’t perform its function to prevent corrosion of the drivetrain, so that is a serious problem

Test the Engine Live

Run the engine at full throttle to identify hidden flaws
.Power the engine to the maximum and check for the fluctuations of the RPM, oil pressure, and water temperature
Also, examine the stuffing box for leaks, check shaft alignment and hose-to-fitting seals for leaks
