The Cessna 185 is already a great performance machine but when you need a little more we're here to help. Wipline floats and AirGlide skis are some of our best know modifications but we also have performance modifications.

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.

Call us today to learn more about this exciting product that is sure to enhance your investment and your total flying experience.

IO550The IO-550D Engine Upgrade can give your 185 that extra get up and go that you've been wishing for.
