I threw a rod and had to take apart the powerhead. Now, delicate as I tried to be, I shattered just about all of my piston rings getting this thing back together. Anyone know the part number for this, or perhaps the bore size for a 1958 Johnson 5.5 hp? Also, what is the trick to getting the piston back in its home without spending my life savings (and free time) tracking down tiny pieces of metal?
