Changing the spark plug wires in your 1999 Mercedes-Benz is quite simple. The spark plug wires simply lift off. The new spark plug wires can be pushed onto the spark plug. It is best to change one wire at a time.
one at a time
The spark plugs are on the front and back of a V6 (back ones are tough to get to) L4 right in front. Turn the engine off and take off the spark wires unscrew the plugs
If you open the hood and can see only 3 spark plug wires: you have 6 cylinder engine. Otherwise you have 4 cylinder engine (you can see only 4 spark plug wires).
The 1999 model, 90 hp Mercury outboard requires an NGK BUHW-2 spark plug, standard plug wires are acceptable.
CHange the spark plugs from the bottom of the engine. Hope we've pointed you in the right direction.
you can either jack it up and crawl underneath or remove the motor mount and lift the engine forward to reach the coil pack and spark plugs from the top
You need to replace your spark plug wires!! You can check this by spraying water on your spark plug wires when it is dark. Then start your engine and you should see the wires arc and your engine will be running rough just as it does when it rains or after a rain. Good Luck
The spark plug locations are all on the same side of the engine. They are in the side of the head, where the plug wires are connected.

pull the old spark plug out then put the new one>>>>>>.sukcer
use a 10mm socket to remove all the bolts on the plastic cover on top of the engine. be careful, there are probably some on the left side(when you're facing the engine) as well as the top. after that, pretty simple
