Product catalog summary

Specifications
The document outlines the specifications of the Caterpillar 3196 Marine Propulsion Engine, a 6-cylinder, 4-stroke-cycle diesel engine. It is turbocharged and aftercooled, with a displacement of 12 liters (732 cubic inches), a bore of 130 mm (5.1 inches), and a stroke of 150 mm (5.9 inches). The engine is IMO compliant and features an electronic governor. The net dry weight is approximately 1142 kg (2515 lb). The cooling system capacity is 45 liters (12.0 U.S. gallons), and the lube oil system refill capacity is 28 liters (7.5 U.S. gallons), with an oil change interval of 250 hours.

Standard Equipment
The engine includes a corrosion-resistant sea water aftercooler, a self-priming sea water pump, a water-cooled manifold and turbocharger, and an electronic service meter. It also features a gear-driven oil pump, a center sump oil pan, and a front support mounting system.

Accessory Equipment
Optional accessories include air starting motors, alternators, digital tachometers, engine monitoring systems, and various kits for customization and enhanced functionality.

Performance
The engine delivers 425 bkW (570 bhp) at 2300 rpm. Performance data is calculated under specific conditions and may vary based on application and operating conditions. The engine is designed for planing hull vessels and other marine applications, with a typical operational range of 1000 to 3000 hours per year.

Performance Curves
The document includes detailed performance curves for both metric and English units, illustrating engine power, torque, and fuel consumption across different engine speeds. The engine's power output is rated in accordance with NMMA procedures, with adjustments for propeller shaft power.

Rating Definitions and Conditions
The engine is rated for planing hull vessels such as pleasure craft and harbor patrol boats, with typical usage of 250 to 1000 hours per year. The rated speed is 2300 rpm, with a maximum cruise speed of 2100 rpm and a maximum continuous cruise speed of 1900 rpm. Ratings are based on standard conditions of 100 kPa, 25°C, and 30% relative humidity.

Dimensions
The engine's overall dimensions are provided, including length, height, and width measurements, with specific details on mounting hole diameters and positions. The overall length is 1874.6 mm (73.8 inches), height is 1004.5 mm (39.6 inches), and width is 968.6 mm (38.3 inches).

Applications
The engine is suitable for various marine applications, including offshore patrol boats, customs and police vessels, and fishing boats. It is designed to handle cyclical engine loads and speeds, making it ideal for vessels with varying operational demands.

Additional Information
Materials and specifications are subject to change without notice, and additional ratings may be available for specific customer requirements. Consult a Caterpillar representative for more information.
