2003 50hp best pitch to have

I have a 2003 50 hp on a 15'.6 Stratos Bass Boat, The prop that is on there is a 13,,I thank white alum. There is not a Marine close to take it to. The problem I am having is with the boat planning out,,,with 2 people in the boat seating down ( 400 plus pounds ) I have to have the other person stand-up in the front of the boat until the front starts to come down,,,and the I can get 32 miles ahour top steed.... I hope that by changing the prop this will be taken care of..

Putting a smaller pitch prop on it should improve hole shot. The rpm range for that motor is 4500-5500 rpm range. Be carefull not to exceed 5500 rpm's at wide open.
