What type of engine powers the Piper PA-28-235?

The Piper PA-28-235 is powered by the Lycoming O-540 engine. This engine is a six-cylinder, naturally aspirated engine that produces a higher horsepower output than the O-320, making it suitable for the PA-28-235, which is designed for improved performance compared to the lower-powered variants.

The O-540 engine contributes significantly to the PA-28-235’s ability to carry loads and maintain better climb performance, especially at higher altitudes or in hot weather conditions. Its reliability and proven performance in light aircraft make it a fitting choice for this model.

While the other options present other engine types often found in the Piper aircraft family or other aircraft types, they do not match the specific engine installed in the PA-28-235. The O-320, for instance, is used in lower-powered models, and the Continental engines mentioned are not correct for this particular Piper model.
