What stainless Steel Prop?

Can anyone please suggest what size Stainless Steel Prop I shall need for my 200 Mercury Optimax in order to increase both acceleration and top speed when carrying an average load of say 4-6 people in my 6.4? Perhaps 21"?

In order to answer this question it would help to know:
  1. What size and make of prop you are running.
  2. What speed you are getting
  3. What revs you are getting
  4. What the engine will rev too
It is unlikely you will increase both speed and acceleration anyway so you may have to make a choice - remember everything is a compromise!
