story i got was mercury employee(s) started ppt after mercury closed stillwater

That's where I looked. I know it's a Magnum but aren't they all "Magnums" in that era, even the 330 hp versions ?

all magnums ? i don't think so,
tons of searching when i was looking for an engine leads me to believe
7.4 bravo is 330
454 mag is 365 and forged rotating assy

87 was the year they called 330's magnums. They were hooked to alphas cuz TRS was done and bravo wasn't out yet. They had the power to blow an alpha's brains out, so maybe by that definition they were magnums...

My 1993 454 mag in my Baja was 365hp. It had a Weber Carb, but I know Q Jets were used on them also depending serial#

TRS weren't done till '93.

it was available to buy. It was no longer installed in new boats. I have seen some confusion where some 330's come up as mags on some websites. Take a magnet to the intake manifold. If it sticks it is a 330.

serial number comes back to 1991 454 Bravo. Magnum W/PS. It was manufactured 10/90. It was originally sold in a 1991 and put in a 28 Apache Brave. Don't see any other info on engine.

wow!
