IO-550D Engine Upgrade

More power? Greater performance? One of the most effective ways of enhancing the capability and performance of your C-185 is to add an IO-550 engine and Hartzell or McCauley “Power Prop”. Wipaire pioneered this modification, realizing its potential to really create a hot-rod of a seaplane. The Wipline IO-550 upgrade is rated at 300 Horsepower, like the standard 520, but is rated at a higher torque, giving you 8-10% better performance, an additional 150 to 175 points of thrust for seaplanes, and quieter ride. Unlike the 520, the IO-550 enables a maximum continuous cruising rate at 300 HP instead of just 285HP.
