Continental introduces drop-in engine replacement for Cessna 172s

By General Aviation News Staff · July 24, 2019 ·

Continental introduced a new STC to install a Prime IO-370-DA3A engine into Cessna R and S series C172s at EAA AirVenture Oshkosh 2019.

The fuel-injected 4-cylinder powerplant is an economical option to replace the original engine at TBO for 180 horsepower Cessna 172 R and S models, according to company officials.

The Prime IO-370-DA3A delivers 180 horsepower, includes roller tappets, and comes with a recommended TBO of 2,200 hours that extends to 2,400 hours for high utilization aircraft, officials added.

The STC includes the engine, a Bendix impulse coupled ignition system to provide improved starting and reduced magneto maintenance, a starter, fuel system, and associated STC paperwork to complete the installation on Cessna 172s currently using a Lycoming IO-360-L2A engine. The STC is priced at $27,226.

The complete kit is available to order, with deliveries starting in September 2019.

    This is likely a Mattituck engine from the engine shop of Mattituck Long Island NY. They sold Lycoming parts compatible engines for many years. Contiential owned them and moved them to Alabama. Had a Mattituck O-540 in a 182RG. Worked just as well as a Lycoming.

    What they need is to make this, or another STC for the engine available to the older 172’s. Lot’s of older models with the O-300 that could use this engine. Unfortunately the price of the STC and cost of a new engine greatly exceed the retail value of these same planes.

    Why a TCM O-360 or IO-360 engine isn’t available by STC for a 172 is beyond me. They are great engines, and would boost power by up to 30 hp for newer Hawks….up to 60 for older ones.

    Really..? A TCM engine with the cam above the crankshaft and the starter out front ? Have the Chinese copied the Lycoming IO-360 and bored it a bit ? [ Aviation Industry Corporation of China ].

    They may ‘steal’ some business from Lycoming with this engine…

    I do like the new cylinders with the modified intake port, that make more HP.

      I didn’t really look at the photo till I read your post. It looks exactly like a copied lycoming, right down to the cast oil sump with the intake routed through it. About the only thing that doesn’t scream “Lycoming” is the cylinder heads.
