Stingray Boat- 3 to 4 blade Prop switch???

[Tu_Madre]

I am wanting to switch from my 3 blade AL prop to a 4 blade AL prop for better holeshot while doing watersports. Maybe to a Solas Amita 4 AL Prop in a 14X21 Pitch. Can someone run the numbers below for me and tell me if it should be a good fit. Will usaually have about the same people as below on the boat. We will be skiing, tubing, and wakeboarding. Two of the skiier/wakeboardes are 250/260lbs guys... so will need some gitty-up to get them up on the skis/boards in deep water starts.

Boat: 2008 Stingray 195LX (20 hrs on boat and motor)
Length 19'6", Beam 91", Weight 2580lbs.
Z-Plane Hull Design
850lbs of People/ Gear,
35gal. Fuel Tank (3/4 Full)
Smart Tabs
Transom Angle: 15?
Deadrise Angle: 19?
Motor/Drive: 2008 Volvo Pinta 4.3GL/SX V6 Carbed 190HP
Full Throttle Operating Range: 4200-4600RPM
Max Engine Speed, RPM: 4600
Gear Ratio: 1.79
Prop: 14"x23" Aluminum 3 blade Part# 48-832834A45

Stingray,

Maybe to a Solas Amita 4 AL Prop in a 14X21 Pitch.

That will be a perfect fit, and you will be extremely happy with the new thrust and hole shot available from this prop when pulling heavy skiers. Your RPM should rise to right at 4,550 RPM and you should lose less than 2 MPH.
