Continental IO-346

The Continental IO-346 engine is a fuel-injected four-cylinder aircraft engine that was developed especially for the Beechcraft Musketeer Custom III by Continental Motors. It was produced for that aircraft between 1965 and 1969.

Design and development
There is no carbureted version of the engine, which would have been designated O-346 and therefore the base model is the IO-346.

The IO-346 was designed to run on 91-98 avgas. The engine has a dry weight of 269¾ lb or 297 lb including the generator and starter. The ignition system consists of dual magnetos, one Scintilla S4RN-201 and one S4RN-205 or, alternatively, two Slick Electro 449 magnetos.
