23 with 200 Prop Choice ?

[abl1111]

Question -

My brother bought an imposter SeaCraft 23 - a Palm Beach. He's running a 200 yam 4 stroke with a standard prop that came with the rig ( not sure of model ) and at 5600 RPM's is hitting 32 mph.

Is this the right prop ? Or is there a better option ? Know 200HP is light in power, but thought it would do better than that.

Thx
