So you're looking at the Rotax 916 iS. Yeah, it's the big dog of light aircraft engines. Liquid-cooled, turbocharged, all that fancy stuff. As of early 2025, if you're buying new and straight from the factory, you're looking at somewhere between $55,000 and $65,000 USD. That gets you the engine core itself—the long block—plus the ECU and the turbo system. But here's the thing nobody warns you about: that's just the start. By the time you add in the mandatory bits like the exhaust, the propeller, and shipping, you're looking at a whole different number. Don't get blindsided. Honestly? It's the tech inside it. This isn't your grandpa's carbureted Lycoming. The 916 iS runs full electronic fuel injection, dual-channel FADEC that basically manages everything for you, and a liquid-cooled turbocharger that lets you fly high without the engine gasping for air. All that stuff costs money to develop and build. But the payoff is real—better fuel efficiency, more power per pound, and it just feels modern. For builders working on experimental or Light Sport Aircraft, it's kind of the gold standard right now. For that $55k-$65k, you get the engine block, cylinder heads, the FADEC ECU (which is like the brain of the whole operation), sensors, wiring harness, turbocharger, and fuel injection system. That's the core. What you don't get? The exhaust system, intercooler, airbox, radiator, hoses, and the propeller speed reduction unit—the gearbox. Those are often sold separately or as part of a "power pack" kit, and they add up fast. Don't assume the base price covers everything you need to actually fly. To get this thing actually running and ready for takeoff, you've got to budget for a bunch of extras. Here's a rough breakdown of what you're probably looking at: In North America, your best bets are authorized distributors like Leading Edge Air Foils (LEAF), California Power Systems (CPS), and Lockwood Aviation. You can also order straight from Rotax in Austria, but shipping gets pricier. Prices do vary a bit between distributors based on what they've got in stock and the support packages they throw in. Shop around a little. Used ones? Good luck. The 916 iS is still pretty new—certified around 2021-2022—so finding a used engine is like finding a unicorn. If you do stumble upon one, expect to pay $45,000 - $55,000. But be careful. These engines need specific maintenance records and often have digital logbooks. If there's no full service history, walk away. The FADEC and turbo system are complex enough that a gamble isn't worth it. The Rotax 916 iS cranks out a maximum takeoff power of 160 horsepower (119 kW) at 5800 RPM. Continuous power is 150 hp. It's the most powerful engine in the Rotax 9-series line, hands down. Some aircraft parts suppliers offer financing through third-party lenders, but it's not super common. Most folks pay cash or use a credit card with a high limit. Interest rates tend to be higher than for a complete aircraft loan, so keep that in mind. The dry weight of the Rotax 916 iS—without oil, coolant, or propeller—is about 162 lbs (73.5 kg). That includes the gearbox and turbocharger, so it's pretty impressive for the power it makes. Yeah, it's EASA and FAA certified for use in certified aircraft under Part 23. But it's also crazy popular in Experimental/Amateur-Built (E-AB) and Light Sport Aircraft (LSA) categories. Versatile little beast.How much does a Rotax 916 is cost
