Mercury High 5 Prop with Mercruiser 4.3 MPI

[anw]

Hi there. Is anyone running a Mercury High Five prop with a Mercruiser 4.3 MPI on an 18-20 foot boat? I'm looking to try one to give the best holeshot for skiing and trying to determine if I need a 17 or 19. I'm currently running a Revolution 4 17pitch and need to be careful not to over rev the engine. Thanks very much.
