Hello again.
Once again I need some help. My 35h evinrude 35953A is running like dung. In neutral it runs fine but in forward gear once you get moving good “fish finder” says about 7mph the motor performs a thump which physically shakes the whole boat, when this happens the water stops flowing from the nipple and stops coming out of the exhaust. Within the span of a second everything is back to normal except it keeps thumping. I guess coughing is more like it. Any suggestions? “I’ve replaced coil packs, spark plugs and wires hoping it was a spark issue. We’ve played with the timing and no results. Tried leaning out the flow and increasing it. Also today it would increase rpms without anybody being at the controls.
