Some where between a 15" to 19" pitch seems to be the norm for the 150 horse on these boats.
Sorry I'm not more specific, I haven't ventured far from my 14x19 stainless prop. It has covered most aspects of what I want the boat to do. A 17" pitch would be a safe starting point not knowing your boating habits. Heavy loaded boats may need a lower number, light loaded may need a higher number. Subtle changes in motor height on the transom will correct a lot of performance problems as will a different type of prop in the same diameter and pitch. Hopefully one of these other guys can get you a lot closer than me. Oh, Welcome to the site, pictures are expected!

You don't say cuddy or CC or Dually??
I had a cuddy and carryed a lot of weight so getting out the hole quick and power was for me, I used a 15 x 15 1/4 was perfect. But as said 17 is were to start with the others, depends what you are looking to get from your boat?
