Pardon me for the simple question, but I replaced the coils on my 1985 Mercury 20hp 2 cycle and I forgot which spark plug wire connects to the top spark plug and which to the bottom spark plug. I was actually smart enough to take a photo of the coil wiring but not smart enough to take a photo of...
I have a 1985 Mercury 20hp motor. I rebuilt the carb this spring and it works great...for a while. I turned the mixture screw all the way to the right & 1 3/8 turns back. Set like that the engine starts first pull, isles in neutral and idles for trolling. However, after running it for over 15...

Secondly, I have installed the alternator kit and...
1980 Silverline with a 470 Mercruiser that pulls to port. Should I adjust the trim tab anode to correct this? and how much in which direction.
I know it's a simple question, but I'm new.
