what plugs??

[brunolund]

i've got a 96 merc 4.3, which i have changed to one from a 90 jimmy.
what plugs should i use for this set up? not sure if the automotive ones would be the same as marine. i'm using the ignition from the 96, but the motor is a 90.

Sorry to jump thread, but I figured Bondo might be able to help me as well.

I have a 1977 mercruiser 4cyl 120 serial number 4511xxx. It is always referenced by hp, so I don't know if this is a 2.5 or what.

I changed plugs this weekend and Napa had Champion plugs that fit. Are these ok or should I get Delcos?

Thanks Bondo (or anyone else that wants to chime in)!:redface:
