What is the price of a full engine rebuild?
If you’re dealing with minor engine damage or simple wear and tear, rebuilding your engine is usually going to be the better option than replacing it entirely. On average, an engine replacement costs between $4,000 and $6,000, whereas an engine rebuild usually ranges between $2,500 and $4,000. A replacement impeller kit for a small engine (6hp) costs $30-40. I could imagine $70 isn’t unreasonable for materials on a bigger engine (especially since yards typically charge a fixed markup above their procurement cost). That leaves $635 for labor, which at 3 hrs is $210/hr.
How long will an engine last after a rebuild?
The Average Lifespan of a Rebuilt Engine Typically, a well-rebuilt engine can last 100,000 to 150,000 miles or more, offering a lifespan comparable to a new engine. Modern diagnostics and machining tools have greatly improved the precision and reliability of rebuilt engines. Jet engines, despite being integral to an aircraft’s operations, do not last for its entire lifespan. Over time, engines experience wear and tear, requiring replacement or overhaul. For narrowbody engines, replacement or overhaul is typically necessary after approximately 12,000 flight cycles.
Is it cheaper to rebuild or replace an engine?
Cost-Effective: Rebuilding an engine is often cheaper than replacing it with a new or remanufactured one, especially if the damage is minimal. Labor costs are lower since you’re not installing an entirely new engine. A remanufactured engine could be $3–8k, which also gives you more reassurance and probably a warranty, but that is assuming you can get one. A new engine is obviously the best and most costly option, at probably $8–12k.
