General Information

This Detroit 471 engine is a two-cycle, 4 cylinder engine with a displacement 284 cubic inches and 5 main bearings.

Normal oil capacity is between 15 to 20 quarts. The oil filter should be changed every 100 hours. The oil should be changed every 100 hours as well, for new engines, though this can be gradually increased. For vehicle use, this translates to every 1000 to 3000 miles, with highway use needing less frequent changes than consistent stop and go conditions.

This engine can be referred to by different names, such as GM 471 or 4-71 Detroit Diesel.

Horsepower and Torque

The information below is based on brake horsepower, and a 471T generator set.

Standby: 180 BHP at 1500 RPM, 210 BHP at 1800 RPM.

Prime: 164 BHP at 1500 RPM, 191 BHP at 1800 RPM.

The information below is for marine pleasurecraft, with N80 injectors. The horsepower is measured as shaft-horsepower. Performance is with paragon 2:1 gear and 12 volt, 25 amp generator.

SHP (Power propeller load): 25 at 1200 RPM, 35 at 1400 RPM, 75 at 1800 RPM, 105 AT 2000 RPM, and a maximum of 160 at 2300.
