210 Horsepower STC for Cessna R172K 'Hawk XP

Over 400 Cessna R172K owners have installed our 210 horsepower conversion on the 'Hawk XP airplane.  The conversion is relatively simple to accomplish.  The original 195 horsepower at 2,600 RPM is reconfigured to 210 horsepower at 2,800 RPM.  The modification requires overhaul of the propeller governor, overhaul and remarking of the tachometer and manifold pressure/fuel flow gauge, and resetting of the low pitch stop on the propeller.

The additional horsepower all goes to acceleration on takeoff and increased rate of climb making the Cessna R172K an extremely high-performance airplane.  You may find more information on our web page under the Isham Cessna 210 horsepower modification or on our catalog page.
