that  green 5.5 proved to be a chalenge for me  when the  GC shock absorber  got stretched.  I think it was damaged  it when I dropped it on the  cement floor  or… it was stretched before my purchase ???

I eventually resorted to  tack welding the silly thing  at the recommended  6 in.11/16   otherwise  it would bind. and plagued my  reseal job.  now using a brass drive pin on the prop.

 

 

You did good on that shock absorber!  That spring cannot stretch.  If one end or the other slips the unit would not get longer.  A spring is an inclined plane.  When it breaks the coils ride up on each other causing the assembly to get longer.  I learned the hard way on the first one I worked on.  Pulled it down three times before I figured it out.  When it gets longer there is a good chance that the lower water pump housing will crack.  You will have a bugger of a time sealing that gear case.  I took a hammer to the shock absorber on my bench.  I wanted to see what was inside.  It is a simple device, one end of the spring is pressed into the top and the other end is pressed into the bottom.   I weld every one I work on now.   OMC did not expect these motors to last this long!

Couple things you may or not know about that 1954 10hp Johnson.  That is the first year for the clam shell hood.  The only Johnson to have silver wings on the hood.  Last year (until modern times) for the automatic reverse lock.  Last year for the four bolt lower unit.  One of the best runners I own!  The leg has been painted the hood is original.
