HELP! Have Pair Racing Props Don't know what drive they fit
 

Hello,

I'm a new here. I have a racing Prop question and was told This is the place to come for the answer so...here I am.
I have a PAIR ( RH / LH) of ROLLA 4-Blade Stainless Racing props. 16 3/4 X 22 and 16 3/4 X 21...Really nice clean props.

They Have 26 Splines and Thats all I know about them. MY biggest question: What Drives will these fit?

I thought SpeedMaster but I saw that Speedmaster drives use 19 Spline Props.

Thanks for the help!

Anyone missing a set of Rolla's? :eek:

By the way...these props aren't "Hot". I aquired them as a Go-with in a (non -racing) boat deal. I restore boats mostly commercial work boats and will be the first to admit that I don't know much about O.S. Race boats.

Totally Legit Props though. (Wanted to make that clear and not leave the wrong impression).

Thanks,

The only odd thing about these are pitch. 21" pitch and 22". I think these are actually a 25 tooth spline not a 26 tooth as there is little call for such a small pitch unless someone is running a diesel or a 1:1 ratio.

If you got them with a boat, what drives were on the boat?
