Can someone please help, Motor was running fine and then started having trouble when I was last on the water it would run fine but miss here and there.
but now it has lost power and will not stay idleing in the water, I have cleaned carbs, replaced fuel pump, tried new gas on portable tank, replaced plug wires, new power pack, new coils, new spark plugs, checked compression and is a little low but is within spec on all 4, 78-77-78-80 is my results tested like manual said these were my numbers last season and boat ran fine did good all through this summer. While running on muffs in yard idles fine but when I pull the plug wires from 2 top cylinders does not make a difference, when I pull the 2 bottoms it will shut motor down. I have good blue spark to all four cylinders but when I pulled the 2 top cylinder spark plugs they are wet and not been firing. Can someone please help I am stumped... ready to throw away and get me another motor.
