I've got a 1980 merc 200(20hp, 2 cylinders) with bad ignition on cylinder #1. While running it in a barrel in gear I tried to adjust the timing but when I throttle up cyl #1 misses terribly - I changed the plugs - no effect. I was thinking it may be the coil but then thought that a bad coil won't fire at all - correct me if I'm wrong on that. Could it be the stator or switch under the flywheel? It has the thunderbolt elect. ignition. <br /><br />I was looking at the plugs and the #1 plug looks brand new with no fouling on it at all. I saw another post with a similar problem and the consensus was that there was water getting in the cylinder and steam cleaning the plug and at the same time causing the misfire.<br /><br />So what do you think would be the culprit? A leaky gasket or an electronic/coil problem?<br /><br />Any help would be appreciated- I'm leaving Thursday to go fishing and I need this motor to work!<br /><br />Thanks<br /><br />OK, <br /><br />Just found out that the motor is actually a 1972 model and most likely has points for the ignition, not electronic ignition.<br /><br />Again any help is appreciated.
