I have a 1991 292 SR1 with a pair of 502s from the factory.They are the Mark IV Mags.There were only 4 of these boats with this set up from the factory.

I know that the HP 500's built in 1995 had finned blue valve covers and then in 1996 and up they were flat with the mirror decal on them. In 1998 they added the "official engine of APBA" or something like that logo on the mirror section of the decal. I thought 1995 was first year for the "HP500" , but maybe it was 1994. Prior to that I thought they were 465's (and had finned valve covers that were black).

Look at these 2 links to get an idea of the years. The first link is for The high performance engines, And the second link is for the stock engines. http://www.mercruiserparts.com/selec...asp?type_id=8H
