Hi All<br /><br />Just thought i would give you some feedback on my Johnson 115hp and the mech removing the thermostats and skimming the head.<br /><br />Eventually found out that the thermostats have been put back in, i think only after i questioned the mechanic. I don't think i will ever find out how much was taken of the heads. <br /><br />The poor running has now (I say no because it's been at the boat shop for two months) been diagnosed as bad coils. Other efforts have been Fuel pump, clean carbs, timing etc<br /><br />The symptoms are one bank of cylinders not getting warm when running, but there is a spark,(trust me when i removed the lead with the engine running). Surely if i can feel the shock there should be a spark? He said that the coils are breaking down under load.<br /><br />I am now questioning everything this guy does to my boat, so your feedback is appreciated.<br /><br />Regards Stephen
