Is the motor a 2 stroke or 4 stroke?What year?Welcome we need more info.If you read the stickies at the top of the page and the helps at the prop store page it will help yopu understand prop selection a little better. We need yor present max rpm and speed to do it right. A tinytach is $40 and easy to install.A gps is excellent for speed.The motor needs to opewrate within its rated rpm range.
A stainless is uneccessary and complicates selection when going from aluminum.

It might work for stumps but rocks you better check with the others that boat in the area.I'm guessing a ss is 2 to 3 times the cost of al and probably twice the cost to repair.Usually refered to as soft contact.sand and mud not rocks and stumps.Maybe I missed something. If your hub doesn't work right ss transmits more stress to the gearcase.
