Hey Bud,
Easy now, easy. Slow down. Most of the members here are saltwater folks and you are at the western base of the Smokey Mountains, at least a few hundred miles from the east coast.
I did a search on Google for a 175HP outboard for you and came up with this website you might want to check out.

It is apparently devoted to Bass Boats and may be very productive for you. I didn't register, so I can't give you a lot of info, but check it out and you might check out other similar sites.
We all love our SeaCrafts, but keep in mind they are primarily a saltwater boats because of their superior ability to handle the water conditions found on open water.
Try some of the more freshwater focused sites like the one I suggested and you might have some good luck finding that "needle in a haystack" you're looking for.
If you own a Seacraft, cherish it! It will still run in freshwater too.
Good Luck.
