    The only way that it can take 50:1 is if its fully jeweled.. IE has roller bearings for every bearing.. easiest way to know for sure is to look at a parts digram for it..

    the 1963 i know for a fact was pre full jeweling for OMC.. in a nut shell the brass bushings they used for bearings tend to not like 50:1 fuel oil mix for very long.
