SuperHawk
For 1968 - 1986 Cessna 172 Models I, K, L, M, N, and P
Your 172 is a great plane but, lately you’ve been thinking it’d be nice to have a little more power. With more “oomph” you’d need less distance to take off, you’d be able to carry more weight, cruise faster, and fly higher. You’d be happier. You’d be safer. You won't have to sell your 172 and buy a 182. You'll save money!
RAM160
For Piper Cherokee Models PA-28-140 & PA-28-151 Or Cessna 172 Models I, J, K, L, & M
Add the RAM 160 STC to your Penn Yan Aero overhaul and enjoy the benefits of 160 horsepower. This is the least expensive horsepower increase available.
DeltaHawk
For Cessna 172 Model N
Increase the safety and value of your Cessna 172N by installing a Lycoming factory rebuilt O-320-D2J or O-320-D2G engine in place of your O-320-H2AD. You’ll benefit from a zero-time logbook, an increase in gross weight capacity of 100 pounds, and the added safety of two separate magnetos.
