Re: what plugs??
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:
