Trojan Boat Forum

I have a 1976 318 and am wanting to replace the spark plugs. The Champion plugs in the manual are no longer made. I went to the Champion site and they give me a replacement choice. However when I search google for suggested plugs, there are differences out there. Can anyone make a suggestion as to what plugs to purchase. The boat has electronic ignition not points etc. It does have a coil with an external resistor

Thanks in advance.

John, contact Beacon Marine, here or go directly to the Trojan store on line. I think I saw spark plugs, etc for your Chrysler 318.
