I think it was 2002. I've had two of them and they have been great motors. Strong foundation for more power too.

I f I am not mistaken, 2001 was the crossover year they offered both the 502 MAa and the 496.

I have a 502, but when looking for a boat, I was told to stay away from 2001 496's. New engine had a lot of glitches and took a year to iron out.

The 502 burns a little oil but is a very reliable engine. Especially 415hp on stock parts, you can't go wrong.

I haven't done any, but there is a huge aftermarket upgrade path for the 502, so if that is your thing, this is definitely the motor for you.

JMHO

Great engine but HORRIBLE stock exhaust that will revert and leak water badly. Be sure to check out the valve stems/exhaust ports on salt water 502MPI's.

502's had very stout internals with the exception of mediocre valve train and crappy low tension metric rings that allow them to often have oil control problems,Smitty

Agree w/ Mike on that one. Some of the late 90's ones had problems with the intake manifold as well.

Ditto! That's what killed my 454 Mag MPI.

I have heard of water intrusion on a few 454/502 mags. How do you know if it's happening?
