What is the difference between the Blue and Black motors? The Blue motors are Mercury Racing, did they use better parts? Did they make more horsepower than advertised? My new boat is coming with Blue HP500 carb engines.

420/465/500/525SC/500 Bulldog/600SC/800SC/900SC/1000SC

That's all I can think of & they were all black pre-1992/3 I think.

The HP465 was a bad-a$$ motor. It did have a very snotty cam, although it was not a roller-cammed motor it did have Crane Gold roller-rockers and 2.25/1.88 valves with a 800 Holley carb.
We had one in a 226ES Baja back in the day. Nice motor. Got lots of attention at the docks with the cam it had.

There was a 800EFI also that, along with the 1000SC was sold as a "race only engine". The 800EFI had a Hillborn style injection setup on it and Pontiac style heads (I think)

Merc went from black to blue in the early 90's on the Merc Racing stuff (HP & SC series). They are all built in FonduLac, WI.
All the same stuff in a black HP500 vs a blue HP500.

When did they come out with the 1000SC motor and when did they stop making it. Also what makes it a race motor what does it have.

Yep, you're right. I built two 32s with the 450s. Found the pictures in my pile. They ran as good as the 500s.
