Changing spark plugs on MCM 4.3L

[i'monaboat]

Does anyone have a diagram that shows where the spark plugs are located at on a MCM 4.3L? The cap is on the top of the engine and i can see the wires going down and it looks like they are underneath the engine. Is this correct? How in the world do you get to them??

They will be under the manifolds in the heads. Get to them any way you can... socket, extensions, flashlight, stand on your head. Its all part of working on boats

Your going to have to follow the wires down to em. They don't come off until the wire does first, so that's where I'd start. Pull one wire off, and do one plug at a time unless you know the firing order on the dizzy
