GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
Most models of the 1993 90 and 115 used the gearcase with the two part driveshaft PN 435474. You will need to compare the part numbers between your motor's model number and the donor motor and be sure that they have the same driveshaft. You can easily switch the shift rods. http://epc.brp.com/default.aspx?brands=ej&lang=e
