1980 Evinrude 7.5hp lower unit interchange

[kprey73]

hello, I have a 1980 evinrude 7.5hp with lower unit in a box in pieces (bought it that way $75) there are gears that are chipped/stripped, wondering what years and hp ranges will fit on this motor

Mo# E8RCSS

Serial# E0001410

the motor is in nice shape looks like new underhood great compression,spark
would be a shame to part it out

thanks much in advance
