Easily add more horsepower with Whipple's upgrade kits.

Whipple MerCruiser

If you’re looking for up to 85 additional horsepower from a stock MerCruiser 8.2-liter engine, Whipple Industries can find those ponies with a reliable upgrade. Whether it’s the base MerCruiser 8.2 or the HO version, Whipple offers mechanical and digital optimization. Each package is offered with calibrations for stock exhaust manifolds, catalytic converters and aftermarket headers.

Features include increased rev limiters for better propping options; increased fuel and spark curve for more power gains through the power range; and easy installation. The upgrade works with digital or conventional shift and throttle systems, and custom calibrations are available. Go with the Stage 1 upgrade for $795 and you’ll pick up 55 hp and 15 foot-pounds of torque as well as an increased rpm limit up to 5,400, plus a boost in torque. Pay $895 for the Stage 2 upgrade and you’ll pick up 85 hp and 50 foot-pounds of torque. You’ll get the most out of the motor if you run 91 octane.
