Re: 1979 200 johnson does it have slow
deerslayer,<br /><br />To the best of my knowledge, that motor only has an alarm.<br /><br />On some Johnson/Evinrudes the temp sensor is only on one cylinder bank.<br /><br />Not sure which you have.<br /><br />To check, see if there are sensors on both heads.<br /><br />They will have a tan wire going to them.<br /><br />I'm sure someone else in this forum will give you a better answer, I just figured I'd give it a shot.<br /><br />Good luck.
