I have a 1999 Yamaha 40/28 Jet Drive outboard motor. I was reading some old threads and came across this one about upgrading the power head from 40 HP to 50 HP by replacing the corroborators and exhaust.

Does anyone have more information on how to do this. Part numbers and how hard is it to do?
Thanks.
