I have a Mid 80's 115 mercury and it will run fine for a few minutes then it will start slowing down till it goes around five miles per hour and bogs. If I put it in neutral it will rev up fine. The one thing i cannot figure out is that it does fine out of water in gear. I replaced all the fuel lines and the fuel filter. This still didn't help so i replaced the bulb and this didn't help as well. I also checked the gas tank for bad gas and resedue. any suggestions?
we cleaned the carbs and didn't rely see anything that would cause a problem. Could it have a coil bad or a spark plug bad. It will only go up to about 2000 rpms, then it just stays steady at that. It won't plain out or anything.
I have a 115 mid 80's. At times it will run on 3 cylinders. I have replaced the stator coils and the switch boxes. It appears that there are multiple versions of these parts. Is there a cross reference of stator version number vs switch box version?
And how about that electronic timing box with three leads. Should it be removed?
