It's one to one no matter which direction correct? Just have to not forget about which way to shift. The prop I started with is a left hand.

Right hand rotation will be clockwise when looking at the prop from the rear when in forward. Left hand, or standard rotation will be counterclockwise viewing from the rear

Only certain velvet drive transmissions can be run at full speed in either direction. I don't think you have one that does that.

Your helm is on the starboard side and would benefit from right hand, counter rotating drive. But if your engine and transmission are standard rotation, you must use left hand props.

no,
that transmission is to turn the same direction as the engine rotation. you do not run that transmission in reverse to run an opposite turning prop.
If you have a L/H turning engine, then you set up that transmission for L/H, and you use a L/H prop.

I understand. The prop I got on EBay was the only 10x11 that I saw. I am about to run out of summer to work this planning problem out. Oh well I'll keep looking. Thanks for the help.

I was not having any luck solving my RPM issue as I couldn't find a prop with less pitch. I did solve the problem with a motor swap. I replaced my 120 Mercruiser with an OMC 5L. No rpm and prop problem now. I did develop porpoising at higher speeds. I cured this with Bennett trim tabs. Let me just say the Bennett Trim tab company went above and beyond to correct the the incompetence of the goofball company that I purchased my original tabs through. They had sent a hodgepodge of unassociated parts and argued about it but Bennett said that I should just send it all to them and they would make it right and they did. Great company!
I do have a question for you. I tightened up my stuffing box nut prior to my last boat ride but at the end of the trip I had more water in the sump than usual. I am using the old rope/grease stuffing. I would like something better what would you recommend?

I got the old-school stuffing box and I run dripless.
There is some newer type rope stuffing that is a teflon product, along with teflon grease, put 2 or 3 rings of the rope in and stagger the joints.
Be very careful cutting the rings with a new razor blade, and get the joints perfect
