Caterpillar 3508C Engine Overview
The Caterpillar 3508C is an eight-cylinder V-type four-stroke diesel engine within Caterpillar's 3500 engine platform.
Marine propulsion configurations use a 170 mm cylinder bore and 190 mm piston stroke, giving a displacement of approximately 34.5 litres.
Applicable commercial marine propulsion configurations cover approximately 775–1,100 bhp (578–820 bkW) with rated speeds within approximately 1,200–1,600 rpm.
The marine propulsion configuration uses turbocharging and aftercooling and is designed for demanding commercial marine applications.
Individual Caterpillar 3508C engines can differ according to:
- Engine serial-number prefix
- Engine arrangement
- Power rating
- Duty cycle
- Application
- Fuel-system configuration
- Turbocharger arrangement
- Cooling-system arrangement
- Electronic control specification
- Emissions configuration
- Accessory equipment
- Production revision
For this reason, a request stating only:
“Caterpillar 3508C parts”
may not provide enough information to identify the correct component.
Always provide the complete engine serial number and arrangement number whenever possible.
