Re: lower unit

Tradin<br /><br />I think your Canadian made motor is a late 78 maybe even early '79.<br />Firstly, as you said, "They didn't make and 80hp that year..<br /> http://www.dougrussell.com/partscatalog/images/MERMAR/74962/43.gif <br />Have a look at Ser Group #15 7116222 lines up with 5193258 .. Your no is higher.<br />Look here <br /> http://www.marineparts.com/partspages/techhelp/images/TECH158.gif
