I have a 1985? Mariner 50hp 4 cylinder S/N 6591223 that has low compression but has been running okay until recently. I think the current problem may be the stator,trigger or switch. The motor stated to bog at wide open throttle about a month ago but would run fine at about 75% so I rebuild carbs, fuel pumps, primer bulb and lines and it didn't do anything to fix the problem. The other night it ran for about five minutes and it quit firing on the top two cylinders, took it out the next night and it ran fine for a few minutes and did the same thing. Does this sound like a stator? I did an Ohms test and resistance between the red and red/white was 157, book says it should be 56-76.Back to the compression, it only has around 70 psi in each cylinder which I know is low but I'm trying to just get by this year and I already have parts to rebuild it this winter. Any help would be appreciated.
