Never seen a 2 blade myself. What I have read on it is back in the "old" days people used them more for "race" applications since they were easier to work on/mod. A 3 blade is for overall performance. A 4 blade typically has more/better low end torque and better low speed maneuvering characteristics with a slight loss to overall top end speed. Why ski boats typically have a 4 or more blade props. Pure speed isn't as important on a ski boat. Getting out of the hole fast/quickly is and being able to maneuver quickly is. A 4 blade will also hold you better in a turn and be better on rough water.
My thought was... Older heavy boat/older motor. A 4 prop to help with getting it on plane would be the best overall performance option. One could go with a 3 and get the max speed but will be penalized elsewhere.
If you troll another question you might want to ask your prop guy is how a 3 verse 4 will affect your trolling speed.
I am taking a stab at this for info only. I have no direct personal dealings with stuff like this. Just what I have read over the last several years and how I comprehended that info.
