I am going to buy a new motor and have decided on a johnson 4 stroke.<br />I have noticed that the 40 and 50 have the same cubic, weight etc. (everything is the same) and that the hp for the 50 is just on a higher rpm. <br />Are these two the same engine?<br />Can I in a simple way get 50 hp from a 40 motor?<br /><br />Just trying to save some money..<br /><br />Sincerely<br />Arild Sunde<br />Norway
