Johnson J140TLCRN

Hello all,<br />This is my first post and hoping you can help sorry if this question has been asked I searched but could not find. <br />My 140hp johnno has an overheating problem, from cold it will get up and plane but after<br />several mins at 1/2 to max revs the engine dies back to 1500rpm's and goes into limp home mode.<br /><br />The tell tail stream is quite strong but the 2 cylinders on the starboard side of the motor overheats. On land with the muffs on after several mins operation at idle you can not touch the r/h/s cylinders the cylinders on the left are warm as per normal operation. Could this be a<br />thermostat problem??<br /><br />And could any one advise what year my motor is,<br /><br />Regards<br /><br />Pete

Welcome Pete! Good to have another Aussie aboard. You got lottsa friends here too!<br /><br />Motor year is an 84'.<br /><br />Yep, probably is a t-stat problem if the other side is OK. Your t-stats are located down under the exhaust cover in an oblong box. <br /><br />There was just another post with the same problem here just a while ago. I'll find it and post the link for ya'.<br /><br />Look just down the list for "evinrude cooling system diagram" from Cortes165.<br /><br />He's got the same problem you do.<br /><br />If you have anymore questions, don't hesitate to post.
