Re: 93 evenrude 15 HP exceleration
There are only 3 bolts that hold the rewind starter unit on. But there is a neutral safety interlock wire that needs to be disconnected. The top of this wire has a short Ell tucked into the starter housing. If you move the wire as far as possible to the rear of it's slot, it will come out of the housing (possibly by also applying some pressure).
After you remove the breather, the carb is pretty accessable.
