Estimated prop pitch required?

Hi, I also need to select the correct prop for my motor. Mercury Black Max, 175HP, V6. Smallish speed boat, 16foot or so. 1979 model motor. I know how to select the prop, I have read all the threads, but does anyone know a good pitch to start off with for the above boat, just more or less? Thanks.

That's a lot of power on 16' or 17' speedboat. I have a 17' Shakespeare and the max recommended HP is 115HP.Saying that,I know of people who have 150HP on similar size boats.But they are race boats.There may be a plate on the boat stating the max recommended HP
If you are going to put this much weight,I would estimate 350lbs,and power on 16' or 17', then I suggest start with 14"x23P,and before you head out,make sure your life insurance is up to date
All joking aside,if you give her throttle,with that amount of weight and HP on the transom,there's a good chance she will porpoise.If the transom isn't ripped off

Thanks for that. The manufacturer's plate states 150HP as the maximum, but at this altitude a 175HP will perform as a 150 does. Thanks again.
