I don’t have the QD 16 parts diagram but the OMC/BRP part numbers are 584477 for the coils, 580321 for the condensers and 439071 for the carb kit. If you buy them from ‘the other guys’, they would be 18-5181, 18-5199 and 18-7043. I’m pretty sure the 172522 (18-5006) tune up kit is the one for your motor.
