Yes, that's what I'd seen too. Earlier 737 models had smaller engines but modern high-bypass turbofans on the 737 Max require larger air inlet diameter. So, they put the engines in front of the wing in order to be able to elevate them a bit, which induces instability that Boeing countered with the MCAS system that occasionally went haywire and crashed the plane.
