Hi everyone,<br />(63' 40hp Evinrude)<br /><br />This is a follow up post for another thread. I had troubles today on the water. Basically the boat wouldn't get up on plane. Someone thought that I might be running on one cylinder. <br /><br />I checked fuel to both cylinders and everything looks normal. <br /><br />Please remind me again how to check spark without shocking the heck out of myself. I searched the forums but I can't find the right way to check.<br /><br />The lower cylinder has an older plug with a crappy helicoil. The plug is pitch black and came out today after a run very wet with black gas/oil. <br /><br />I think that I will replace the head with a used one from the local salvage yard. But is there anything that I can do in the meantime to fix this?<br /><br />Thanks guys <br /><br />Sal
