Propeller for SC 21
 

Hi again
How do I identify the propeller I have on
As I feel it is not giving the best performance
I would consider another so the next question is
What is the best for my boat to give all round good performance?
And from whom should I purchase

Look on the hub of the current prop - there should be numbers stamped either on the outside between blades (if SS), or on one of the ribs inside the hub (if aluminum).

I've always heard Mercury makes great props. Although I recently installed a Turning Point stainless that I'm pretty happy with (found a good deal).

Let us know your RPM's, engine, etc. and we'll try helping with the choice of a new one.

I think rpm is about 5000
number on hub is 48 832830A45 19p

and engin is 5 ltr
