The prop shaft bushing for the AMEL 55 is not out of stainless steel. Except for the first AMEL 55 boats, the prop shaft bushings are different (the diameter is not the same) and the material is bronze or chromed.
In short, the new type of prop shaft bushing for the AMEL 55 will not fit the shaft of your Super Maramu.
Feel free to take contact with me for any further details.
