This may sound dumb but how do I tell if I have a 15" or 20" transom version of an Evinrude 70hp (AE70TLCDC)?<br />I have measured the mid section from join to join and it is 18".
Ahoy, Greg.<br /><br />Welcome to the board.<br /><br />I believe that the "L" in the model number identifies your engine as a long (20") shaft engine.<br /><br />The measurement you should take is from the mount surface that meets the top of the transom to the anti-ventilation plate.<br /><br />Good luck.
Take a look at the picture in the post link below.<br />You need to measure from the top inside of the transom bracket, to the cavitation plate.<br /><br />This should be aboout the same as the height of the transom. That way, the cavitation plate will be even with the bottom of the boat.<br /><br /> http://www.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=17;t=022180
