Pitch might be different but "prop selection" remains generally the same:

If propping for normal use you prop it to make the median MFG suggested WOT
RPM.

If propping for "hole shot priority" you prop it for median RPM plus 500.

If propping for fuel ecomomy you prop it for the lowest end of the MFG
suggested RPM range.

Anatomy of a hole shot:


Holeshot has a lot more to do with prop selection than 2 vs 4 stroke. I'm
sure
that prop selection would be different between a 2 and 4.
It is really more art than science anyway.
