Not nessessarily a reason to avoid, just be more cautious. New VC's and painting intake doesn't quite fall under tearing into a motor, just blinging it out.

It must be similiar to these Merc 575 hp efi's. The sticker on the manifold says so.

The 2002 575s were supercharged. I wonder what those engines are?? Look like 502Mags and someone swapped the stickers..Slick..Maybe they are the original 540ci 575s from 89...with a rebuild in 2002.

I agree, I think Mercruiser did try to spice up the look at one very short time, Somewhere around that time frame also, Because I am pretty sure I have seen that before myself.

I have seen them in blue before, it could have been that way from the factory. I could not tell you what year or why they did it.

That boat is on winni, I almost 90% it is 415hp

That does look familiar...I knew a guy with a late 90's Baja H2X with a 502 MAG MPI 415 HP (Just like my black one) and I could swear it was painted blue...not sure if it was factory or not.
