Friend of mine has a 1995 454 Mag efi that is junked. Needs a reman long block. Any ideas where to go about getting the correct engine? Everything I've looked at is carb application.

The Gen V(1995-1996) carbed 454mag and 454 EFI are the same longblock and use the same cam.

griff,im pretty sure 96 is gen 6.

Page 40 in the Merc reman guide. Link below for all. Its Merc complete reman guide.

Mike - Merc is group listing their - 454 / 7.4 - 1992 thru 1996 flat tappet engines as GEN V.

Let me know if you want me to order anything for you here. Merc stands behind their remans very well.

i thought gm went to gen 6 in 96.

Mercruiser had both - 1996 model year 454 Gen V and at some point in 1996 had Gen VI for model year 1996 continuing model year 1997 and beyond to 2001 for the black engine production side .

Let me see what I can find & post to show what I am saying here.

here click on link below and then scroll down to the engines - 7.4 listings showing GEN & years and then to reconfirm scroll down to the 454 listings showing GEN & years

Tri-Star engines is who Mercury Recomended for 454 mag efi long block. Since they discontinued the 454 Mag motor.

What sort of prices does Merc get for these?

A couple years newer, but my boat had 2 NEW Long block 454 mag efi 98 gen VI when I bought it. THe owner was buddy with a small boat shop and his dealer cost were around $5k each! I ended up buying boat in 2013 and they were put in 2012 and had 12 hours.
