Indmar 5W-30 Synthetic Blend Motor Oil is formulated from premium synthetic blend base stocks and CleanGuardTM additive technology to deliver trusted engine protection and peak performance.
Compared to cars, towsport specific inboard marine engines produce more low end torque per displacement at lower rpms and have different cooling systems than that of an automobile.
This motor oil is recommended for high performance engines including turbocharged and supercharged engines where a thicker oil film is desired.
General Motors placed the 5.7 liter L31 Vortec in several of its trucks, including the Chevrolet C/K, the Cadillac Escalade and the GMC Yukon. The L31 was the last engine to come out of the first-generation of Chevy small blocks.
The Vortec generated 255 horsepower at 4,600 rpm and 330 foot-pounds of torque at 2,800 rpm, or the force required to move a vehicle forward. It had a displacement -- the amount of air and fuel exited from an engine during a full cycle --of 5,735 cubic centimeters, and compression ratio -- the maximum engine volume compared to the minimum -- of 9.4 to 1.
The dual overhead cam L31 had a front longitudinal design, two valves per cylinder and required a four bolt intake manifold. Its cylinder heads and block were cast iron, it received fuel through a multi-point fuel injection system and its components were compatible with all smaller engines in the Chevy first- generation small block family.

We note this so new and used boat buyers can look to this data when comparing engines in boats. We have seen customers confused when comparing actual data provided by Ilmor and CARB to data provided by a marketing department. Here is a chart showing CARB's test data by engine family. more
Our advice is to use CARB's testing data when comparing engines from different manufacturers because this is the only data compiled using EPA testing standards so the playing field is level. [links]
Engine torque is also very important in marine engine performance. Indmar, the current engine provider to Supra, Moomba, Malibu, & Tige recently switched from GM to Ford based engines. When the switch was made Indmar started marketing engine torque rather than HP. The thing to be aware of is many boat manufacturers, dealers and sales reps represent torque output on Indmar Ford based engines as if it was HP. This is misleading and all of the engines have higher torque figures than HP. more
The link below is for the California Air Resource Bureau (CARB) web site. It takes you to reports which list the specific output of the engines CARB has authorized for sale in the state of California. Output is reported in Kilowatts (kw). To convert kw into horsepower simply multiply the kw rating by 1.34 to see the equivalent horsepower rating. [links]
