How much does a Rotax 912 engine cost

So, you're wondering what a Rotax 912 will set you back. Honestly, there's no single answer—it depends on whether you go new, factory-rebuilt, or used. As of 2025, the most common version, the 912 ULS, runs somewhere between $22,000 and $27,000 USD for just the bare engine core. But wait—once you start adding everything you actually need to fly, that number climbs fast.

What is the price range for a new Rotax 912 engine?

If you want a brand new Rotax 912 ULS (that's the 100 hp one) from an authorized dealer, expect to pay around $22,000 to $27,000 USD for the base model. That gets you the engine itself, exhaust, carbs, and basic ignition bits. But here's the kicker—a "flyable" package with all the extras like the propeller speed reduction unit (PSRU), radiator, hoses, wiring harness, and ECU? That'll run you $30,000 to $35,000 USD or more. Yeah, it adds up.

The fuel-injected version, the 912 iS, is pricier. You're looking at $28,000 to $33,000 USD for the base unit, and complete packages can easily hit $38,000 USD or beyond. Not cheap, but you get what you pay for.

How much does a factory-rebuilt Rotax 912 cost?

BRP-Rotax also sells factory-remanufactured engines—basically rebuilt to like-new condition. They tear them down completely, inspect everything, replace worn parts, and slap on a full factory warranty. A factory-rebuilt 912 ULS typically costs between $16,000 and $20,000 USD. It's a solid middle ground if you want reliability without the new-engine price tag. Just remember—this might not include accessories like a new exhaust or radiator, so check what you already have.

What is the cost of a used Rotax 912 engine?

Used Rotax engines are all over the second-hand market, and prices depend heavily on hours, condition, and how well they were maintained. Here's the rough breakdown:

• Low-time engines (under 500 hours): $12,000 to $18,000 USD
• Mid-time engines (500-1,000 hours): $8,000 to $12,000 USD
• High-time engines (over 1,000 hours or near TBO): $5,000 to $8,000 USD

Watch out, though. A super cheap engine might be close to its overhaul time—TBO is usually 2,000 hours or 12 years, whichever comes first. Always ask for logbooks and do a compression test before handing over cash.

What is the total cost of a complete Rotax 912 installation?

The engine is just the start. A full, ready-to-fly setup for an experimental or LSA aircraft needs a bunch of extra stuff. Here's what you're probably looking at for a 912 ULS installation:

Note: Prices vary by dealer, location, and configuration. Fuel-injected models (912 iS) add approximately $5,000-$8,000 to the total. Always get a written quote from an authorized Rotax service center.

How can I save money on a Rotax 912 engine?

On a tight budget? Try these tricks:

• Buy a factory-rebuilt engine: Saves 30-40% versus new, and you still get a warranty.
• Purchase a used engine with documented history: Look for ones from reputable builders or salvage yards. Compression test is non-negotiable.
• Consider a core engine without accessories: Got a working exhaust, radiator, or PSRU from an old engine? You can skip buying new ones.
• Join owner forums: Rotax groups often have classifieds with fair prices and honest sellers.
