Looks like iboats.com online store has what you want:

Here's another choice with a bigger diameter and greater pitch:

FYI, the OEM two-blade prop (p/n 0385319) is listed as 8X7-1/4. Good luck!

Ok, thanks for helping me with this.
I'm running a 12' aluminum Sears Boat with my son 200lbs, Black lab 50lbs, me 200 lbs or me, wife, dog - 400lbs.

What's best set up for this combo - 6HP
8" prop / 7 pitch or
8 1/4 " prop / 8 1/2 pitch

What is going to get me best performance? Presently using a 8" 2 blade prop , stock, don't know the pitch. thanks again, Matt

Motor came with a 8 X 7 . With your load a 81/2 will be too much.
the 3 blade will probably do better with a load.

I pulled the prop off my 1973 Evinrude 6HP and learned it is OEM p/n 385940. This is a three blade, plastic prop with 8-1/8D X 8P. It is not listed in my parts catalog.
