All you need to do is google it. There will be tons of write ups along with videos that show a step by step process.

You said its a "inboard" but the 4.3 is normally not used with inboard applications. They are normally used with Gen 2 outdrives. With an outdrive you would have an I/O (inboard with outdrive). So if you have an outdrive then the impeller is inside the lower section of the drive

If you do have a external sea pump, then its located on the Starboard side down low



To replace impeller in the drive, the info is here

Easiest way to get actual real life answers here is to post serial numbers and drive type. Otherwise it is likely you'll be talking oranges and everyone else is tossing bananas and pineapples your way.
